Expert Solution

Step 1: Define database.

A database is a methodically structured and orderly assembly of data or information, often digitally stored within a computer system. Its primary purpose is to effectively house, oversee, retrieve, and manipulate data to cater to diverse informational requirements and bolster specific applications or operations. Databases are constructed using tables, records, fields, and connections, facilitating a systematic arrangement and retrieval of data. This renders them a fundamental component of data administration across a multitude of domains, encompassing realms such as commerce, research, and software development.
