SimpleDB
I implementated SimpleDB by C++.
Available Query Types
- Basic data retrieval
select c1, c2 from t1, t2 where c3 = c4
- Nested data retrieval
select c1, c2 from ( select c3 from t1 ), t2 where c3 = c4
- Data aggregation
select count, c1 from t1 group by c1 order by count
- Data insertion
insert into t1 ( c1, c2 ) values ( v1, v2 )
- Create B-tree index
create index indexname on student ( c1 )
Setup
You need a compiler which can compile codes written by C++17.

$ git clone https://github.com/google/googletest.git && mkdir googletest/build && cd googletest/build && sudo cmake .. && sudo make install
