Passage 1Adatabase management system (DBMS)is simply the software that permits an organization to centralize data,manage them efficiently,and provide access to the stored data by application programs.The DBMSacts as an interface between application programs and the physical data files.When the application program calls for data item such as gross pay,the DBMSfinds this item in the database and presents it to the application program.Using traditional data files the programmer would have to define the data and then tell the computer where they were.ADBMSeliminates most of the data definition statements found in traditional programs.Adatabase management system has three components:Adata definition language Adata manipulation language Adata dictionary The data definition language is the formal language used by programmers to specify the content and structure of the database.The data definition language defines each data element as it appears in the database before that data element is translated into the forms required by application programs.Most DBMShave a specialized language called a data manipulation language that is used in conjunction with some conventional third-or fourth-generation programming languages to manipulate the data in the database.This language contains commands that permit end users and programming specialists to extract data from the database to satisfy information requests and develop applications.The most prominent data manipulation language today is Structured Query Language,or SQL.Complex programming tasks cannot be performed efficiently with typical data manipulation languages.However,most mainframe DBMSare compatible with COBOL,FORTRAN,and other third-generation programming languages,permitting greater processing efficiency and flexibility.The third element of a DBMSis a data dictionary.This is an automated or manual file that stores definitions of data elements and data characteristics such as usage,physical representation,ownership (who in the organization is responsible for maintaining the data),authorization,and security.Many data dictionaries can produce lists and reports of data utilization,groupings,program locations,and so on.Which of the following statements is NOTtrue about database
