Common Data Structures And Algorithms Implemented In C++. FOR LEARNING PURPOSES ONLY

GrayDB is a minimal, high-performance embedded database engine written entirely in C. Inspired by the architectural simplicity of SQLite and the modular power of PostgreSQL internals, it uses its own memory-efficient B+ Tree index, open-addressing Hash Table, and a small, expressive domain-specific language (DSL) for querying.

on-disk bptree (b+ tree) data structure implementation

Here we have implemented B-Plus Tree for data block indexing as a data system project

This repository contains several projects that simulates, for example, file system or database manager systems etc.
