This repo contains a primitive DB supporting create, insert and select queries.
An example of the storage structure is given in the data/ folder.
The .metadata file contains the required metadata for the table (names and types of each of the attributes) and the .db file contains the tuples.
The query used to build the example is: create table sample (id int, name string, registered bool).
To insert tuples into the DB: insert into sample (1, harry, true), (2, samuel, true), (3, william, false).
To select, either specify the attributes or use * (select * from sample).
