Abstract
The invention relates to a database management system. The database management system is characterized in that the system is of large-scale software controlling and managing a database and being used for establishing, using and maintaining the database; the system manages and controls the database uniformly so as to guaranteed the security and integrity of the database. The system adopts complex data models to represent data structures, the data redundancy is small, and the system is easy to expand; meanwhile, high data and program independence are provided, the independence of the database includes physical independence and logical independence, and convenient user interfaces are provided for users. The system has four data control functions, namely concurrency control, recovery, integrity and security. Data utilized by application programs of the database are stipulated by the database system uniformly, are organized and established according to the data models and are managed and controlled by the system integrally, and the flexibility of the system is improved.
Description
Technical field
The present invention relates to a kind of management system, particularly relate to a kind of data base management system (DBMS)
Background technology
Various data want taxonomic organization, store and management, need determine on storage level, to organize these data with which kind of file structure and access mode, how to realize the contact between data.User is supplied to realize the adding of data, deletions, renewal, the operation such as inquiry, the normal operation of guarantee Database Systems.
Summary of the invention
Object of the present invention is exactly to improve storage space utilization factor, provides a kind of data base management system (DBMS).
Object of the present invention is achieved through the following technical solutions:
A kind of data base management system (DBMS), relate to management, wherein: this system is the large software of a kind of manipulation and management database, for foundation, operation and maintenance database, it carries out unified management and control to database, to ensure security and the integrality of database.
Above-mentioned a kind of data base management system (DBMS), wherein: this system provides a kind of data definition language (DDL).
Further, above-mentioned a kind of data base management system (DBMS), wherein: the various data manipulation of database and the maintenance management of database are all foundation with database schema.
Further, above-mentioned a kind of data base management system (DBMS), wherein: the application program that contain accessing database statement, is compiled into the target program that can run.
Further, above-mentioned a kind of data base management system (DBMS), wherein: the physical organization of data on peripheral storage facilities and access method are provided.
Again further, above-mentioned a kind of data base management system (DBMS), wherein: system provides software support for data base administrator, comprises the maintenance tools such as Data Security Control, integrity ensuring, DB Backup, database reorganization and performance monitoring.
This system adopts complicated data model to represent data structure, and data redundancy is little, easily expands, and achieves data sharing.Have higher data and program independence, the independence of database has physical independence and logical independence, the user interface provided users with the convenient simultaneously.This system and provide the Data Control function of 4 aspects is con current control, recovery, integrality and security respectively.The data that in database, each application program uses, by Database Systems Uniform provisions, according to certain data model tissue and foundation, are managed and centralized control by systematic unity, add the dirigibility of system.
Embodiment
A kind of data base management system (DBMS), relate to management, its special feature is: this system provides a kind of data definition language (DDL).Be translated into internal representation with the database schema that it is write, the logical organization of database, integrity constraint and physical storage structure are kept in inner data dictionary.The various data manipulation of database and the maintenance management of database are all foundation with database schema.The application program that contain accessing database statement, be compiled into the target program that can run.
Wield interactive query language is provided, and Query Result is presented on screen, the physical organization of data on peripheral storage facilities and access method are provided.There is provided affairs operational management and running log, the Safety monitoring that affairs are run and data integrity inspection, the functions such as the con current control of affairs and System recover.For data base administrator provides software support, comprise the maintenance tools such as Data Security Control, integrity ensuring, DB Backup, database reorganization and performance monitoring.
This system adopts complicated data model to represent data structure, and data redundancy is little, easily expands, and achieves data sharing.Have higher data and program independence, the independence of database has physical independence and logical independence, the user interface provided users with the convenient simultaneously.This system and provide the Data Control function of 4 aspects is con current control, recovery, integrality and security respectively.The data that in database, each application program uses, by Database Systems Uniform provisions, according to certain data model tissue and foundation, are managed and centralized control by systematic unity, add the dirigibility of system.
