Database-D

This project is an implementation of simple database from scratch in one file. It uses B-tree to store tables and Deques to store the data in each table. Database-D has been created as an educational project (database for processing the data about students of some school or university) and not intended for production, at least in current state.

Requirements

• C++ compiler (e.g. gcc or clang)
• Python 3 (for tests)

Install

git clone https://github.com/DavidOSX/Database-D
cd Database-D
chmod +x install.sh
./install.sh

Usage

After you install this database to run it just type:

./database-d

Nowadays you can use these commands:

• 'add' - add student's name and group number
• 'search' - search for a student by the name and the group number
• 'search_by_num' - search for a students by the group number
• 'del' - removal of information about the certain student
• 'del_by_num' - removal of information about the certain group
• 'q' - quit
• 'test' - test the database with the data about 10000 students (you can change size of test dataset if run following command python3 test.py)

Note: group-students tables can be easily correct for arbitrary use
