Database technology refers to the systems and tools used to store, manage, and retrieve data efficiently. It allows users to organize large amounts of information in a structured way, making it easy to access and manipulate. Common types of databases include relational databases, which use tables to represent data, and NoSQL databases, which handle unstructured data. These technologies are essential for various applications, from small businesses to large enterprises. They support tasks such as data analysis, reporting, and transaction processing. Popular database management systems include MySQL, PostgreSQL, and MongoDB, each offering unique features to meet different needs.
