The software used to manage calls and queries (query) the database is called database management system (database management system).The term database (database) originated from computer science. The term was eventually extended to many fields. Actually, the record is similar to the data base already existed before the industrial revolution. These notes form ledgers, receipts, and collection of data related to the business.A collection of notes and pieces of knowledge is the basic concept of the database. A structured database has an explanation of the types of facts stored in it. Such an explanation is called the scheme, which describes an object that is represented in the database and the relationships between those objects.There are many ways in which to organize a scheme or model the database structure. The relational model is a model commonly used today. This model represents all the information in the form of related tables and each table consists of rows and columns.In the relational model, relations antarkabel represented using the same value antarkabel. Models such as hierarchical and network models, using a more explicit way to represent the relationship antarkabel.The term database refers to the collection of data that are interconnected and the software refers to a database management system. If the context is clear, the programmers and database administrators use the term to the second meaning.

In the non-transactional operation, MySQL is superior in terms of performance compared with the database software competitors.
