Database Management involves organizing, storing, and retrieving data efficiently. PostgreSQL, MySQL, Oracle Database, Microsoft SQL Server, MongoDB, and SQLite are popular database management systems.
PostgreSQL, MySQL, Oracle, and SQL Server are relational databases, meaning they organize data into tables with predefined schemas. They use Structured Query Language (SQL) for querying and managing data.
MongoDB is a NoSQL database, storing data in flexible, JSON-like documents. It offers scalability and flexibility for handling unstructured or semi-structured data.
SQLite is a lightweight, file-based database suitable for smaller projects or embedded systems. It doesn't require a separate server process, making it easy to set up and use.
Each system has its strengths and weaknesses, catering to different needs in terms of scalability, performance, and data structure. Choosing the right one depends on the specific requirements of the project.
