A data base is a collection of information that is organized and stored in a computer system. It can contain various types of data, such as text, numbers, images or videos, which are arranged in an efficient manner to facilitate easy retrieval and manipulation. Data bases can be used for many purposes, including storing customer records, tracking inventory levels, managing financial transactions, or analyzing scientific research data. The information stored in a data base is typically accessed through a software application that allows users to query the database using specific criteria, retrieve the desired information, and perform various operations on it such as sorting, filtering, or updating.
