The lab assignments of the course Database Systems. It used to be the homework of BerkelyCS186 , MIT6.830.
SimpleDB is a basic database management system writen in Java. The author have provided a set of mostly unimplemented classes and interfaces. You will need to write the code for these classes. Your code will be graded by running a set of system tests written using JUnit, called System tests. There are also a number of unit tests, which are not used for grading but that you may find useful in verifying that your code works.
There are 6 labs in total and I have completed lab1 ~ lab4. In lab1, I focus on implementing the core modules required to access stored data on disk; in future labs, I add support for various query processing operators, as well as transactions, locking, and concurrent queries.
For lab1~lab4, documents and my reports(in Chinese) are avilable in this repository.
