A database is a structured, digital collection of data. Databases are digital repositories organized for efficient storage, retrieval and management of certain types of data. Data gets stored in tables, each with rows and columns – this structured format helps ensure data integrity and security. Databases aren't just valuable tools for storing data, they make advanced data analysis possible, and they support complex apps that need fast access to data.

Question 5

What are the main types of database?

Accepted Answer

By and large, there are three main types of database: relational, NoSQL and NewSQL. A relational database organizes data into tables and uses a language called SQL to manage the one-to-one relationships. NoSQL is designed for unstructured or semi-structured data and is quite a lot more flexible and scalable. NewSQL is a blend of the traditional SQL and NoSQL systems, meant for high-performance transactions that need scalability and distributed processing.
