btree-index

Key-Value/Document store database library with btree and ARTree indexing methods, SSN-MVCC concurrency

A custom relational SQL database engine built from scratch in C++17 — TCP server, REST API, replication, full-text search, window functions, triggers

concurrent KV-store with a B+-tree index

A simplified relational database management system with support for integer-only tables and matrices. Supports linear hash and B+ tree indices, two-phase merge sort, buffer management and aggregate queries.

This Java package implements a system which searches for some given words into a large number of text files, and returns all the locations where they are found.

Zero-dependency embedded storage engine in C & Java with B+ Tree, WAL, Parquet/Arrow plugins, and multi-language bindings.

A raw SQLite file reader written in x86-64 assembly — parses the file format directly (B-tree pages, varints, record headers) to run a SELECT * FROM table, no SQLite library involved.

A disk-based B+ tree implementation that supports concurrency and transactions

Repository for the "SCC0215 - File Organization" course's project offered for Computer Science undergraduates at ICMC - USP, by professor Cristina Ciferri.

B+tree stored on disk

Project for CS course structures of databases

🗄️ A production-grade relational database (RDBMS) built entirely from scratch in Go. Features a SQL parser, query optimizer, B-tree indexes, transactions, REST API, and modern web dashboard.

Duplicate Removal from Database Relation using B-Trees and Hashing

A project to master database indexing strategies in PostgreSQL by creating and optimizing B-Tree, functional, multi-column, unique, and partial indexes to improve SQL query performance.
