A database is a collection of logically related records or files consolidated into a common pool that provides data for multiple uses. The data is organized according to a database model, with the relational model being the most common. A Database Management System (DBMS) consists of software that organizes database storage structures and allows organizations to control database development through specialists like Database Administrators. DBMSs are categorized by the database model they support, like relational, and determine the available query languages, with SQL commonly used for relational databases.
Database Management System - DBMS
- 1. Compiled: MarkJohnLado 2017 Database Management Systems 2 University of the Visayas Database Systems A database is an integrated collection of logically related records or files consolidated into a common pool that provides data for one or more multiple uses. One way of classifying databases involves the type of content, for example: bibliographic, full-text, numeric, and image. Other classification methods start from examining database models or database architectures. The data in a database is organized according to a database model. The relational model is the most common. A Database Management System (DBMS) consists of software that organizes the storage of data. A DBMS controls the creation, maintenance, and use of the database storage structures of organizations and of their end users. It allows organizations to place control of organization-wide database development in the hands of Database Administrators (DBAs) and other specialists. In large systems, a DBMS allows users and other software to store and retrieve data in a structured way. Database management systems are usually categorized according to the database model that they support, such as the network, relational or object model. The model tends to determine the query languages that are available to access the database. One commonly used query language for the relational database is SQL, although SQL syntax and function can vary from one DBMS to another. A great deal of the internal engineering of a DBMS is independent of the data model, and is concerned with managing factors such as performance, concurrency, integrity, and recovery from hardware failures. In these areas there are large differences between products.
