Low-level database engine in C
A high-performance CRUD system that bypasses high-level abstractions to manipulate raw data streams directly. This project demonstrates deep understanding of file I/O, memory management, and binary serialization using the C Standard Library.
Key Pattern: Synchronous file I/O with manual buffer flushing to ensure data persistence even in the event of software interrupt.
This project demonstrates a low-level implementation of a database engine using the C Standard Library. It showcases how modern databases work under the hood by directly manipulating binary data streams.
Core Architecture
- →Binary file storage with struct serialization
- →Direct byte-offset navigation using fseek()
- →Atomic operations with temporary file swapping
- →In-place updates using rb+ file mode
