In databases, a data category is typically referred to as a "data type." Data types define the kind of data that can be stored in a particular column or variable, such as integers, strings, dates, and so on. Different database management systems offer various data types to accommodate different types of data.
The two major types of databases are relational databases and non-relational databases. Relational databases store data in tables with predefined relationships, while non-relational databases use flexible data models like key-value pairs, documents, graphs, or columns.
Databases contain structured data organized in tables, rows, and columns. They store information such as text, numbers, dates, and other types of data. Databases can also include relationships between different pieces of data, enabling efficient storage and retrieval of information.
Distributed database is one logical database which is spread out over multiple sites, connected by network. It behaves as it were a single database. Decentralized databases are a group of independent databases spead out over different locations. They are not connected and do not share updates between each other.
Keyfields crosslink related records in different tables of Relational Databases. But in other kinds of databases (e.g. navigational databases, object oriented databases, flat file databases) other different mechanisms are used or the linking of records is not supported.

There are several types of databases that can be used for research purposes, including relational databases, NoSQL databases, and data warehouses. Each type has its own strengths and weaknesses, so researchers should choose the one that best fits their needs.
