The document 6 | addresses the storage and buffer manager. Buffer and frame sizes, buffer and frame 7 | storage structures, page formats, page storage structures, file formats, buffering 8 | techniques, hashing techniques, file storage structures, and interface functions for the 9 | disk space and buffer modules will be discussed . The particular technique is chosen 10 | from the material covered in class that are relevant to buffer and storage manager. 11 | 12 | see buffer.pdf for more detail... 13 | 14 | ## What's this 15 | - 研一上修了金老师的adb课程，期末做了个实现buffer的作业； 16 | - 采用C++ 14 STL编程，LRU cache的数据结构主要使用了哈希+双向链表，空间换时间； 17 | - 看着作业需求文档buffer.pdf自己慢慢编的码，个人觉得这个作业还比较有意思所以放上来交流学习； 18 | - 有问题可以提issue交流hhh 19 |
