ShalltearDB

🩸 No SQL database made for C++

Simple database management system implemented in C++. It includes classes for managing tables (Table), a database (Database), and an interpreter (Interpreter) that provides a command interface for interacting with the database.

• The entire database is stored in Hex and Binary
• No pre-encoding required
• No restriction

Commands

Insert(std::string, std::string);
Display();
Save();
Load();
Delete(std::string);
Create(std::string, std::string);
Update(std::string, std::string);

FindById(std::string);
FindAll(std::string);
FindFirst(std::string);
FindAllStartWith(std::string);

SelectByID(std::string);
SelectByName(std::string);
