There are many different types of databases, but four of the most common include:
Hierarchical: Like a family tree, every single object will have one or more objects beneath it. However, no child object can have more than one parent, resulting in complex navigation that’s balanced by high performance, quick query time, and easy access.
Relational: This type of database stores your information in tables that can be joined by specific fields, like user data and purchases information. You’ll usually need to use SQL for multiple operations like updating, creating, and deleting data.
Non-relational: With a non-relational, or NoSQL, database, you can simplify SQL structures through visual functionality that ensures non-tech-savvy users can operate within the system.
Object oriented: You’re using this type of system if you’re managing objects on a database server disk and if the association between objects can persist. This is the most popular programming paradigm because querying complex systems can still be fast and powerful.
