This project was started after a bit of searching for an existing project without much success. 6 | 7 | **Project Benefits** 8 | + SQL scripts for creating schemas and sample data for testing or proof-of-concept applications 9 | + A way to teach developers how to write DDL/SQL 10 | + A database schema design starting point 11 | 12 | **Database examples should contain the following:** 13 | + README file to discribe the purpose of the example, how to use the SQL scripts, and anything else required. 14 | + ER diagram or other database model PNG image 15 | + ER diagram source file (optional) 16 | + Schema creation SQL (DDL) scripts 17 | + Sample data insertion scripts (optional) 18 | + Schema removal scripts 19 | + Database system specific scripts (create database, schema, users/permissions, constraints, etc) 20 | 21 | 22 | 23 | Getting Started 24 | --------------- 25 | 26 | To use the existing examples, clone the entire project or use GitHub to navigate down into the appropriate 27 | folder and copy specific scripts as needed. Each folder should have a description regarding the example's 28 | purpose and design. 29 | 30 | Scripts are organized by database system (MySQL, Derby, DB2, etc) and purpose (create, data, drop). Example 31 | authors are encouraged to create a database-independent version (ANSI/ISO SQL) if possible (generic_create.sql), but many 32 | times this is not practical. 33 | 34 | Contributing 35 | ------------ 36 | 37 | We welcome contributions! All contributions must be original work and willing to be released under the 38 | Apache License 2.0 (liberal open source). 39 | 40 | ### Common SQL Syntax (When Possible) 41 | 42 | Most modern database systems understand some level of ANSI or ISO SQL standard syntax. However most 43 | databases stray from the standard in some unforgivable way. Still, it may be possible to build a schema 44 | in a common syntax that is understood by many systems. 45 | 46 | Common or generic database scripts should be named with the "generic" prefix in the filename. Example: 47 | *generic_schema_create.sql*. 48 | 49 | ### Database Specific Syntax 50 | 51 | There are many cases when database specific syntax is required or strongly desired. The preferred approach 52 | is to use database-specific scripts to alter an existing schema already created with generic scripts. As 53 | a last resort, a completely database specific approach may be used. Either way, document the approach taken 54 | with each schema example. 55 | 56 | Name database-specific files with a reasonable prefix. Example: *mysql_schema_create_alter.sql*. 57 | 58 | ### Database Models 59 | 60 | Creating database models (Entity-Relationship (ER) Diagrams) are useful when provided. Please use a freely available 61 | tool for creating a saving ER diagram files. Also, always export the ER diagram as a PNG image file so others can 62 | view the diagram without using a specific tool. 63 | 64 | -------------------------------------------------------------------------------- /shopping_cart/diagram.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/awesomejt/database-schema-examples/b943416bf6e79582ef69a6e9aadf9d0944126550/shopping_cart/diagram.png -------------------------------------------------------------------------------- /shopping_cart/diagram.uml: -------------------------------------------------------------------------------- 1 | 2 | 3 | DATABASE 4 | f0c20ecd-c44d-4144-b09b-e8d6189fded4.schema:STORE.PUBLIC 5 | 6 | f0c20ecd-c44d-4144-b09b-e8d6189fded4.table:STORE.PUBLIC.CATEGORY 7 | f0c20ecd-c44d-4144-b09b-e8d6189fded4.table:STORE.PUBLIC.CART 8 | f0c20ecd-c44d-4144-b09b-e8d6189fded4.table:STORE.PUBLIC.PRODUCT 9 | f0c20ecd-c44d-4144-b09b-e8d6189fded4.table:STORE.PUBLIC.CUSTOMER 10 | f0c20ecd-c44d-4144-b09b-e8d6189fded4.table:STORE.PUBLIC.CART_ITEM 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | Key columns 39 | Columns 40 | 41 | 42 | 43 | -------------------------------------------------------------------------------- /shopping_cart/generic_create.sql: -------------------------------------------------------------------------------- 1 | CREATE TABLE CART 2 | ( 3 | ID INTEGER PRIMARY KEY NOT NULL, 4 | CUSTOMER_ID INTEGER NOT NULL, 5 | NAME VARCHAR(50) NOT NULL 6 | ); 7 | CREATE TABLE CART_ITEM 8 | ( 9 | CART_ID INTEGER NOT NULL, 10 | PRODUCT_ID INTEGER NOT NULL, 11 | ITEM_QTY INTEGER NOT NULL, 12 | LAST_UPDATED TIMESTAMP DEFAULT CURRENT_TIMESTAMP() NOT NULL, 13 | PRIMARY KEY ( CART_ID, PRODUCT_ID ) 14 | ); 15 | CREATE TABLE CATEGORY 16 | ( 17 | ID INTEGER PRIMARY KEY NOT NULL, 18 | NAME VARCHAR(50) NOT NULL, 19 | DESCRIPTION CLOB 20 | ); 21 | CREATE TABLE CUSTOMER 22 | ( 23 | ID INTEGER PRIMARY KEY NOT NULL, 24 | NAME VARCHAR(100) NOT NULL, 25 | PASSWORD VARCHAR(20) NOT NULL, 26 | LAST_UPDATED TIMESTAMP DEFAULT CURRENT_TIMESTAMP() NOT NULL, 27 | REGISTRATION_DATE DATE DEFAULT CURRENT_DATE() NOT NULL 28 | ); 29 | CREATE TABLE PRODUCT 30 | ( 31 | ID INTEGER PRIMARY KEY NOT NULL, 32 | NAME VARCHAR(50) NOT NULL, 33 | DESCRIPTION CLOB NOT NULL, 34 | PRICE DECIMAL(5,2) NOT NULL, 35 | STOCK_QTY INTEGER NOT NULL, 36 | LAST_UPDATED TIMESTAMP DEFAULT CURRENT_TIMESTAMP() NOT NULL, 37 | CATEGORY_ID INTEGER NOT NULL 38 | ); 39 | ALTER TABLE CART ADD FOREIGN KEY ( CUSTOMER_ID ) REFERENCES CUSTOMER ( ID ); 40 | CREATE INDEX FK_CUSTOMERCART_INDEX_1 ON CART ( CUSTOMER_ID ); 41 | ALTER TABLE CART_ITEM ADD FOREIGN KEY ( CART_ID ) REFERENCES CART ( ID ); 42 | ALTER TABLE CART_ITEM ADD FOREIGN KEY ( PRODUCT_ID ) REFERENCES PRODUCT ( ID ); 43 | CREATE INDEX FK_CARTITEMPRODUCT_INDEX_B ON CART_ITEM ( PRODUCT_ID ); 44 | CREATE UNIQUE INDEX UNIQUE_NAME_INDEX_F ON CATEGORY ( NAME ); 45 | ALTER TABLE PRODUCT ADD FOREIGN KEY ( CATEGORY_ID ) REFERENCES CATEGORY ( ID ); 46 | CREATE INDEX FK_PRODUCTCATEGORY_INDEX_1 ON PRODUCT ( CATEGORY_ID ); 47 | --------------------------------------------------------------------------------
