- Designed a single-user database management system that supports a subset of SQL.
- Implemented heap and sorted file organization to manage database records.
- Added some basic relational algebra operations like select, project, join, sum, group by, and duplicate removal.
- Devised query optimization module to decide and execute the optimized query plan using histograms.
- Added lexer and parser to support sql statement given by user.
- Project was developed in 7 different milestones.
- Project documentation can be found here.
- GTests can be found here.
- To test the database, we are using tpch-dbgen as sample data.
- Clone the tpch-dbgen repo to test.
- Compile it:
make - To generate 10MB data, run
./dbgen -s 0.01. To generated 1GB data./dbgen -s 1. - This will generate 8 *.tbl files containing the data in CSV format with | separator
