 1 | # Social Network Graph Demo
 2 | 
 3 | 
 4 | When you think about a web application, a graph database doesn’t usually spring to mind. Instead, most people just take the familiar route of using an SQL database to store information. While this is perfectly acceptable for most use cases there are sometimes those that would see tremendous benefits by using a graph database.
 5 | In this tutorial, I will show you how to make a basic web application using Flask that stores all of its information in a graph database. To be more precise we are using Memgraph DB, an in-memory database that can easily handle a lot of information and perform read/write instructions quite quickly.<br /><br />
 6 | Our use case is a Social Network Graph (in the code referred to as **SNG** for convenience) representing users and the connections between them. Usually, such a graph would contain millions of nodes and edges and the algorithms that are performed on them don’t do well with data being stored in relational databases.<br /><br />

10 | <p/>
11 | 
12 | ## Start the app
13 | 
14 | Here are the instructions on how to build and start the app:
15 | 
16 | ```
17 | docker-compose build
18 | docker-compose up
19 | ```
20 | 
21 | Once the app is up, head over to the `localhost:5000` to see the demo.
22 | 
23 | To learn how we built the demo, read  our [blog post](https://memgraph.com/blog/how-to-visualize-a-social-network-in-python-with-a-graph-database).

  7 | 
  8 | ## Introduction
  9 | 
 10 | 
 11 | When you think about a web application, a graph database doesn’t usually spring to mind. Instead, most people just take the familiar route of using an SQL database to store information. While this is perfectly acceptable for most use cases there are sometimes those that would see tremendous benefits by using a graph database.
 12 | In this tutorial, I will show you how to make a basic web application using Flask that stores all of its information in a graph database. To be more precise we are using **Memgraph DB**, an in-memory database that can easily handle a lot of information and perform read/write instructions quite quickly.<br /><br />
 13 | Our use case is a **Social Network Graph** (in the code referred to as **SNG** for convenience) representing users and the connections between them. Usually, such a graph would contain millions of relationships and the algorithms that are performed on them don’t do well with data being stored in relational databases.<br /><br />
 14 | In this tutorial, I will show you step by step how to build a simple Python web application from the bottom up so you get a basic understanding of the technologies that are used. You can also find all of the code [here](https://github.com/g-despot/sng-demo) if you don't want to work on it as you go through the tutorial. If at any point in this tutorial you have a question or something is not working for you, feel free to post on [StackOverflow](https://stackoverflow.com/questions/tagged/memgraphdb) with the tag `memgraphdb`.

 19 | <p/>
 20 | <br />
 21 | 
 22 | ## Prerequisites
 23 | 
 24 | 
 25 | Because we are building a complete web application there is a number of tools that you will need to install before we begin:
 26 | * **[Poetry](https://python-poetry.org/docs/)**: a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.
 27 | * **[Flask](https://flask.palletsprojects.com/en/1.1.x/quickstart/)**: a very powerful web framework that provides you with tools, libraries and technologies used in web development. A Flask application can be as small as a single web page or as complex as a management interface.
 28 | * **[Docker and Compose](https://docs.docker.com/get-docker/)**: an open platform for developing, shipping, and running applications. It enables us to separate our application from our infrastructure (host machine). If you are installing Docker on Windows, Compose will be already included. For Linux and macOS visit [this site](https://docs.docker.com/compose/install/).
 29 | * **[Memgraph DB](https://docs.memgraph.com/memgraph/quick-start)**: a native fully distributed in-memory graph database built to handle real-time use-cases at enterprise scale. Follow the **Docker Installation** instructions on the Quick Start page. While it's completely optional, I encourage you to also install **[Memgraph Lab](https://memgraph.com/product/lab)** so you can execute **openCypher** queries on the database directly and see visualized results.
 30 | 
 31 | <br />
 32 | 
 33 | ## Creating the Project Structure and Handling Dependencies
 34 | 
 35 | 
 36 | Sometimes standard packaging systems and dependency management in Python can be confusing for beginners so we decided to use Poetry.<br />
 37 | To start building our project structure choose a working directory and run:
 38 | 
 39 | ```
 40 | poetry new sng-demo
 41 | ```
 42 | 
 43 | Now you should have a directory with the following content:
 44 | 
 45 | ```
 46 | sng-demo
 47 | ├── pyproject.toml
 48 | ├── README.rst
 49 | ├── sng_demo
 50 | │  └── __init__.py
 51 | └── tests
 52 |    ├── __init__.py
 53 |    └── test_poetry_demo.py
 54 | ```
 55 | 
 56 | In this tutorial, we won’t use the testing functionalities so go on ahead and delete the directory `tests` as well as the file `README.rst`.
 57 | 
 58 | Now we need to add the dependencies for our project. Given that we are going to run the app inside a Docker container we don't need the dependencies installed locally, only inside the container. Copy the files [`project.toml`](https://github.com/g-despot/sng-demo/blob/master/pyproject.toml) and [`poetry.lock`](https://github.com/g-despot/sng-demo/blob/master/poetry.lock) and place them in the root directory of the project. The only other thing we need to do about dependency management is to tell Docker how to run Poetry on startup so it can install/update all the necessary dependencies inside the container.<br /><br />
 59 | 
 60 | 
 61 | ## Dockerizing an Application
 62 | 
 63 | 
 64 | In the root directory of the project create two files, `Dockerfile` and `docker-compose.yml`. At the beginning of the `Dockerfile`, we specify the Python version and instruct the container to install **CMake**, **poetry**, **mgclient** and **pymgclient**. Poetry is necessary to manage our dependencies inside the container while CMake and mgclient are required for pymgclient, the Python driver for **Memgraph DB**.<br />
 65 | You don’t have to focus too much on this part just copy the code to your `Dockerfile`:
 66 | ```dockerfile
 67 | FROM python:3.7-slim-bullseye
 68 | 
 69 | # Install pymgclient
 70 | RUN apt-get update && \
 71 |     apt-get install -y git cmake make gcc g++ libssl-dev && \
 72 |     git clone --recursive https://github.com/memgraph/pymgclient /pymgclient && \
 73 |     cd pymgclient && \
 74 |     git checkout v1.1.0 && \
 75 |     python3 setup.py install && \
 76 |     python3 -c "import mgclient"
 77 | 
 78 | # Install poetry
 79 | RUN python3 -m pip install -U pip \
 80 |  && python3 -c "import urllib.request; print(urllib.request.urlopen('https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py').read().decode('utf-8'))" | python3
 81 | 
 82 | ENV PATH="${PATH}:/root/.poetry/bin"
 83 | ```
 84 | Next, we define the working directory with:
 85 | ```dockerfile
 86 | WORKDIR /app
 87 | COPY poetry.lock pyproject.toml /app/
 88 | ```
 89 | The second command will enable us to cache the project requirements and only reinstall them when `pyproject.toml` or `poetry.lock` are changed.
 90 | ```dockerfile
 91 | RUN poetry config virtualenvs.create false && \
 92 |   poetry install --no-interaction --no-ansi
 93 | ```
 94 | We don’t need to create a virtual environment because our application is already isolated by being in a Docker container. To disable it `virtualenvs.create` needs to be set to false.<br />
 95 | The second line in the command ensures that Poetry asks us no interactive questions while installing/updating dependencies and it makes the output more log friendly.
 96 | ```dockerfile
 97 | COPY . /app
 98 | EXPOSE 5000
 99 | ENTRYPOINT [ "poetry", "run" ]
100 | ```
101 | This is where we essentially create all the directories and files inside of our container. The `EXPOSE` command informs Docker that the container listens on the specified network port at runtime.<br />
102 | 
103 | Next, we need to create a `docker-compose.yml` file. **Compose** is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration. For our project, we need two services. One is the web application (`sng_demo`) and the other a database instance (`memgraph`).<br />
104 | 
105 | If you followed the instructions on [how to setup Memgraph DB with Docker](https://docs.memgraph.com/memgraph/quick-start) correctly you only need to add the following code to your `docker-compose.yml` file to run the container:
106 | ```yaml
107 | version: '3'
108 | services:
109 |   memgraph:
110 |     image: memgraph/memgraph
111 |     ports:
112 |       - "7687:7687"
113 |   sng_demo:
114 |     build: .
115 |     volumes:
116 |       - .:/app
117 |     ports:
118 |       - "5000:5000"
119 |     environment:
120 |       MG_HOST: memgraph
121 |       MG_PORT: 7687
122 |     depends_on:
123 |       - memgraph
124 | ```
125 | When it comes to the `ports` key, there is an important distinction between the **HOST_PORT** and the **CONTAINER_PORT**. The first number in the key is the **HOST_PORT** and it can be used to connect from your host machine to the service (for example with **Memgraph Lab**). The second number specifies the **CONTAINER_PORT** which is used for service-to-service communication. More precisely, our service `sng_db` can use this port to access the service `memgraph` and connect to the database.
126 | 
127 | The `environment` key contains `MG_HOST` and `MG_PORT` which represent environment variables in the service’s container. They store the `memgraph` service address and port which are needed to establish a database connection.
128 | The `depends_on` key is used to start services in dependency order because we need the database to start before the web application.
129 | 
130 | The `build` key allows us to tell Compose where to find the build instructions as well as the files and/or folders used during the build process. By using the `volumes` key, we bypass the need to constantly restart our image to load new changes to it from the host machine.
131 | 
132 | Finally, we have a dockerized project that utilizes Poetry! This approach is great for development because it enables us to run our project on completely different operating systems and environments without having to worry about compatibility issues.
133 | <br /><br />
134 | 
135 | 
136 | ## Web Development with Flask
137 | 
138 | 
139 | Flask is very simple to use so why not create a **Hello World!** page to try out our Docker+Poetry setup.<br />
140 | In the project root directory create a file called `app.py` with the following code:
141 | ```python
142 | from flask import Flask
143 | 
144 | app = Flask(__name__)
145 | 
146 | 
147 | @app.route('/')
148 | @app.route('/index')
149 | def index():
150 |    return "Hello World"
151 | 
152 | ```
153 | First, we imported the Flask class and then created an instance of it. The `route()` decorator tells Flask what URL should trigger our function.
154 | Now, we need to tell Docker how to run our app. This can be done by creating a simple script in the project root directory. Let’s call it `start.sh`:
155 | ```bash
156 | #!/bin/bash
157 | export FLASK_APP=app.py
158 | export FLASK_ENV=development
159 | flask run --host 0.0.0.0
160 | ```
161 | Setting `FLASK_ENV` to `development` will enable the debug mode. This makes Flask use an interactive debugger and reloader.<br />
162 | Setting `FLASK_APP` to `app.py` specifies how to start the application.<br />
163 | We need to tell Docker when and how to run this script so put the following code in your `Dockerfile` after the line `EXPOSE 5000` :
164 | ```dockerfile
165 | ADD start.sh /
166 | RUN chmod +x /start.sh
167 | ```
168 | The command `chmod +x` makes the script executable by setting the right permission.<br />
169 | To execute the script, add the following command after the line `ENTRYPOINT [ "poetry", "run" ]`:
170 | ```dockerfile
171 | CMD ["/start.sh"]
172 | ```
173 | That’s it! Our first web page is ready so let’s start our app to make sure we don’t have any errors.<br />
174 | In the project root directory execute:
175 | ```shell
176 | docker-compose build
177 | ```
178 | The first build will take some time because Docker has to download and install a lot of dependencies.<br />
179 | After it finishes run:
180 | ```shell
181 | docker-compose up
182 | ```
183 | The URL of our web application is http://localhost:5000/. When you open it there should be a message **Hello World!** which means that the app is up and running.<br /><br />
184 | Now it’s time to create a more complex web page that will contain our Social Network Graph. In the project root directory create a folder called `templates` and in it a file with the name `base.html`. This will be our base HTML template for other pages. Copy the code:
185 | ```html
186 | <!doctype html>
187 | <html lang="en">
188 | 
189 | <head>
190 |     <meta charset="utf-8">
191 |     <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
192 | 
193 |     <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
194 |     <link rel="stylesheet" href="/static/css/style.css">
195 | 
196 |     <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
197 |     <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
198 |     <script src="https://d3js.org/d3.v4.min.js" charset="utf-8"></script>
199 | 
200 |     <title>Social Network Graph Demo</title>
201 | </head>
202 | 
203 | <body>
204 |     {% block content %} {% endblock %}
205 | </body>
206 | 
207 | </html>
208 | ```
209 | We also need to create an HTML file for our actual landing site that utilizes this base file and an accompanying JavaScript file. Create the HTML file in the same location with the name `index.html` and copy the following code into it:
210 | ```html
211 | {% extends 'base.html' %} {% block content %}
212 | <div class="container">
213 |   Hello World!
214 | </div>
215 | <script src="/static/js/index.js" charset="utf-8"></script>
216 | {% endblock %}
217 | ```
218 | In the project root directory create a folder called `static` with one subfolder called `js` and another called `css`. The `js` folder will contain all of the needed local JavaScript files while the `css` folder will contain all the CSS stylesheets. In the `js` folder create a file called `index.js` and in the `css` folder one called `style.css`. Just leave them empty for now.<br /><br />
219 | If you want to find out more about web development with Flask I suggest you try out [this tutorial](https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world).<br />
220 | Your current project structure should like this:
221 | ```
222 | sng-demo
223 | ├── sng_demo
224 | │  └── __init__.py
225 | ├── templates
226 | │  └── index.html
227 | ├── static
228 | │  ├── css
229 | │  │  └── style.css
230 | │  └── js
231 | │     ├── base.html
232 | │     └── index.js

238 | └── start.sh
239 | ```
240 | <br />
241 | 
242 | 
243 | ## The Data Model and Database Connection
244 | 
245 | 
246 | In the app directory `sng-demo` create a folder called `database`. This folder will contain all of the modules that we need to communicate with the database. You can find them [here](https://github.com/g-despot/sng-demo/tree/master/sng_demo/database) and just copy their contents. They are closely related to the database driver and if you wish to examine them a bit more I suggest you look up the driver documentation [here](https://github.com/memgraph/pymgclient).
247 | In the app directory `sng-demo` create the module `db_operations.py`. This is where all the custom database related commands will be located.<br />
248 | The `sng_demo` directory should look like this:
249 | 
250 | ```
251 | sng_demo
252 | ├── __init__.py
253 | ├── db_operations.py
254 | └── database
255 |    ├── __init__.py
256 |    ├── memgraph.py
257 |    ├── connection.py
258 |    └── models.py
259 | ```
260 | We will use a very simple data model that can be easily upgraded later on.<br />
261 | There is only one node with the label `User` and each `User` has two properties, a numerical `id` and a string `name`. Nodes are connected with edges of the type `FRIENDS`:
262 | 
263 | <p align="center">
264 | <img src="https://github.com/g-despot/images/blob/master/user.png?raw=true" alt="Data Model" width="250"/>
265 | <p/>
266 | 
267 | There are several methods to populate our database ([more on that here](https://docs.memgraph.com/memgraph/how-to-guides-overview/import-data)) but we will be doing it manually by executing **openCypher** queries so you can get a better understanding of how to communicate with the database. You will find all the necessary queries to populate the database in the files [`data_big.txt`](https://github.com/g-despot/sng-demo/blob/master/resources/data_big.txt) and [`data_small.txt`](https://github.com/g-despot/sng-demo/blob/master/resources/data_small.txt). The former just has a larger dataset than the latter.<br />
268 | In the project root directory create a folder called `resources` and place the files in it. Now you can add an import method to your web application.<br />
269 | In the module `db_operations.py` add the following import and method:
270 | 
271 | ```python
272 | import json
273 | 
274 | def clear(db):
275 |   command = "MATCH (node) DETACH DELETE node"
276 |   db.execute_query(command)
277 | 
278 | def populate_database(db, path):
279 |   file = open(path)
280 |   lines = file.readlines()
281 |   file.close()
282 |   for line in lines:
283 |       if len(line.strip()) != 0 and line[0] != '/':
284 |           db.execute_query(line)
285 | ```
286 | The method `clear()` deletes any data that might have been left in the database before populating it.<br />
287 | The method `populate_database()` reads all of the **openCypher** queries in the specified file and executes them.<br />
288 | In the module `app.py` change the imports and method `index()` to:
289 | 
290 | ```python
291 | from flask import Flask, render_template, request, jsonify, make_response
292 | from sng_demo.database import Memgraph
293 | from sng_demo import db_operations
294 | 
295 | app = Flask(__name__)
296 | 
297 | 
298 | @app.route('/')
299 | @app.route('/index')
300 | def index():
301 |     db = Memgraph()
302 |     db_operations.clear(db)
303 |     db_operations.populate_database(db, "resources/data_small.txt")
304 |     return render_template('index.html')
305 | ```
306 | Now every time we refresh our index page the database is cleared and repopulated with new data. While this is not suitable for the production stage, it is highly useful during development because it will enable us to make changes in the data without having to restart the whole application or working directly on the database.<br />
307 | If you want to examine the graph before proceeding, I suggest you open **Memgraph Lab** and run the query `MATCH (n1)-[e:FRIENDS]-(n2) RETURN n1,n2,e;`.<br />
308 | The result should be:
309 | 
310 | <br />
311 | <p align="center">
312 |    <img src="https://github.com/g-despot/images/blob/master/sng_lab.png?raw=true" alt="Data Model" width="900"/>
313 | <p/>
314 | <br />
315 | 
316 | We also need a method in our app to fetch all the relevant data from the database when a client requests it.<br />
317 | Let’s call it `get_graph()` and place it in the `db_operations.py` module:
318 | 
319 | ```python
320 | def get_graph(db):
321 |    command = "MATCH (n1)-[e:FRIENDS]-(n2) RETURN n1,n2,e;"
322 |    relationships = db.execute_and_fetch(command)
323 | 
324 |    link_objects = []
325 |    node_objects = []
326 |    added_nodes = []
327 |    for relationship in relationships:
328 |        e = relationship['e']
329 |        data = {"source": e.nodes[0], "target": e.nodes[1]}
330 |        link_objects.append(data)
331 | 
332 |        n1 = relationship['n1']
333 |        if not (n1.id in added_nodes):
334 |            data = {"id": n1.id, "name": n1.properties['name']}
335 |            node_objects.append(data)
336 |            added_nodes.append(n1.id)
337 | 
338 |        n2 = relationship['n2']
339 |        if not (n2.id in added_nodes):
340 |            data = {"id": n2.id, "name": n2.properties['name']}
341 |            node_objects.append(data)
342 |            added_nodes.append(n2.id)
343 |    data = {"links": link_objects, "nodes": node_objects}
344 | 
345 |    return json.dumps(data)
346 | ```
347 | 
348 | First, we need to execute the **openCypher** query `MATCH (n1)-[e:FRIENDS]-(n2) RETURN n1,n2,e;` and return its results from the database. These results will contain all the edges in the graph as well as all the nodes that are connected to those edges. Nodes that don't have connections will not be returned and that's ok for now.<br /><br />
349 | The results (the object `relationships`) are in the form of a generator which we can iterate over and access its contents by using the node/edge names specified in our initial query (`n1`,`n2` and `e`).<br />
350 | We also need to check if a node has already been appended to the `node_objects` list because multiple edges can contain (point to or from) the same node. All of the objects are stored in key-value pairs suitable for later JSON conversion.<br />
351 | The final result is a JSON object containing:
352 | * `links`: all the relationships that are in the graph as pairs of `source` and `target` id properties,
353 | * `nodes`: all the nodes from the graph that form relationships with other nodes.
354 | 
355 | In your `app.py` module add the following method:
356 | 
357 | ```python
358 | @app.route("/get-graph", methods=["POST"])
359 | def get_graph():
360 |    db = Memgraph()
361 |    response = make_response(
362 |        jsonify(db_operations.get_graph(db)), 200)
363 |    return response
364 | ```
365 | 
366 | This method is responsible for responding to POST requests from the client. It returns the graph data that we fetched from the server in the previous method.<br /><br />
367 | Now let's do something with this data! Copy the contents for your `index.js` file [from here](https://github.com/g-despot/sng-demo/blob/master/static/js/index.js)
368 | and the `style.css` file [from here](https://github.com/g-despot/sng-demo/blob/master/static/css/style.css).<br />
369 | We also need to add the actual SVG graphic to our page so change the `index.html` file to:
370 | ```html
371 | {% extends 'base.html' %} {% block content %}
372 | <div class="container">
373 |     <svg class="border rounded mt-3" width="960" height="600" style="background-color:white"></svg>
374 | </div>
375 | <script src="/static/js/index.js" charset="utf-8"></script>
376 | {% endblock %}
377 | ```
378 | I won't go into much detail about how to use **D3.js** so if you want to find out more I encourage you to visit [their website](https://d3js.org/).<br /><br />
379 | In short, we fetch all the nodes and edges from the database and add them to an SVG element. The visual representation of the graph is made by simulating how physical forces act on particles (charge and gravity). You can drag and drop the nodes, hover over them to see the value of their name property, zoom in and out of the graph and move the SVG graphic.<br /><br />

385 | <br />
386 | 
387 | 
388 | ## Additional Functionalities
389 | 
390 | 
391 | Go ahead and copy the file [`query.js`](https://github.com/g-despot/sng-demo/blob/master/static/js/query.js) to the directory `static/js` and [`query.html`](https://github.com/g-despot/sng-demo/blob/master/templates/query.html) to the directory `templates`. You can find the updated `base.html` file [here](https://github.com/g-despot/sng-demo/blob/master/templates/base.html). Copy the necessary methods from the [db_operations.py](https://github.com/g-despot/sng-demo/blob/master/sng_demo/db_operations.py) module and [app.py](https://github.com/g-despot/sng-demo/blob/master/app.py) module.<br />
392 | After you made the changes, just open http://localhost:5000/query/ and see the results.<br />
393 | This page will make your life easier if you want to debug the data being fetched from the server. It returns all the nodes or edges and shows them in a JSON highlighted format.<br /><br />

431 | ## Conclusion
432 | 
433 | 
434 | Even though graph databases have been around for a long time, they are still not considered a mainstream tool in software development. **Relational database-management systems** model data as a set of predetermined structures. Complex joins and self-joins are necessary when the dataset becomes too inter-related. Modern datasets require technically complex queries which are often very inefficient in real-time scenarios.<br /><br />
435 | **Graph databases** offer powerful data modelling and analysis capabilities for many real-world problems such as social networks, business relationships, dependencies, shipping, logistics... and they have been adopted by many of the worlds leading tech companies. With this tutorial, I hope to shed some light on how easy it is to integrate a graph database in your development process and I encourage you to try it out yourself.<br /><br />
436 | As I said at the beginning, feel free to ask us any questions about this tutorial or Memgraph in general on [StackOverflow](https://stackoverflow.com/questions/tagged/memgraphdb) with the tag `memgraphdb` or on our official [forum](https://discourse.memgraph.com/). **Good luck with your coding!**<br /><br />
