Data retrieval is the process of obtaining data from a database management system (DBMS) . The data is represented in a structured way, and there is no ambiguity in data. To retrieve the desired data, the user presents a set of criteria by a query, and then the DBMS selects the demanded data from the database. A query language, like Structured Query Language (SQL), is used to prepare the queries. Reports and queries are the two primary forms of the retrieved data from a database. Queries generally select a relatively small portion of the database, while reports show larger amounts of data. Reports are designed using a report generator built into the database management system. Data retrieval is crucial for data analysis, decision-making, and reporting. It enables users to efficiently access and utilize data. Data retrieval also ensures the confidentiality, integrity, and availability of the data while protecting it from unauthorized access or tampering.
