Explanation of terms What is a database system

Database, a warehouse that holds data, a database system, a database, a database management system, hardware, and an operator.

A database management system is a system used to manage data and databases.

Database system development tool, with database management system as the core, uses high-level language to develop a set of database application system software for fool users.

The database system includes the database management system, the software developed by the database and the database development tool (database application system).

Is the database system development tool a database management system or a database management tool?

Management tools, because many users do not know how to use databases and database management systems, only use simple application software, so it is necessary to have technical personnel to use database development tools to program software for these simple users.

What is the difference between a database management system and a database system development tool?

The former is at the heart of the latter's development software, and the latter has to write programs in high-level languages in addition to using it as a benchmark.

Is the database management system already installed when installing the operating system?

If you don't install it, you generally have to install it extra, such as VFP, PB, SQLSEVER, etc.

A database system (DBS) is a complex system that is a computer system that employs database technology. DBS is not just a set of software that manages databases (i.e., DBMS), nor is it just a database (DB). DBS is a practical and operational system that stores, maintains and provides data support to application systems according to the database method, it is a collection of storage media, processing objects and management systems, which is composed of four parts: database, hardware, software and database administrator.

1. Data is a physical symbol of load or recorded information arranged and combined according to certain rules.

It can be numbers, text, images, or computers**.

2. A database is a warehouse that organizes, stores, and manages data according to a data structure.

3. Database management system is a large-scale software for manipulating and managing databases, which is used to establish, use and maintain databases, referred to as DBMS.

It manages and controls the database in a unified manner to ensure the security and integrity of the database.

4. The database system is the use of the database can be realized in the program, but also in the independent data operation interface, for example, in the SQL Server database system, we can use the T-SQL language to operate the database, and we can also use the SQL Server enterprise manager to realize the operation and management of the database.

The database system is a kind of ideal data processing system developed to meet the needs of data processing, and it is also a software system that provides data for the actual operational storage, maintenance and application system, and is a collection of storage media, processing objects and management systems.

The system is generally composed of four parts: the database, which is managed by the database management system, and the insertion, modification and retrieval of data are carried out through the database management system; hardware, the various physical devices that make up a computer system; software, including operating systems, database management systems and applications; The data steward, who is responsible for creating, monitoring, and maintaining the entire database so that the data can be used effectively.

1. Database:

A database is a warehouse that organizes, stores, and manages data according to its data structure.

There are many types of databases, from the simplest to store all kinds of data, to large database systems that can store massive amounts of data.

2. Database management system:

Database management system (database

management

system) is a large-scale software that manipulates and manages databases, and is used to establish, use, and maintain databases, abbreviated as DBMS.

The database management system manages and controls the database in a unified manner to ensure the security and integrity of the database.

3. Database system:

Database system dbs (data

BaseSystem (DBS) typically consists of software, database, and data administrators.

The database system is an ideal data processing system developed to meet the needs of data processing, and it is also a software system that provides data for the actual operational storage, maintenance and application system, and is a storage medium.

A collection of processing objects and management systems.

A database system is a system composed of a database and its management software.

The database system is a kind of ideal data processing system developed to meet the needs of data processing, and it is also a software system that provides data for the actual operational storage, maintenance and application system, and is a collection of storage media, processing objects and management systems. The individual meaning of database system refers to a specific database management system that destroys the system software and the data fiber database established with it; Its disciplinary meaning refers to the discipline composed of theories, methods and technologies involved in the research, development, establishment, maintenance and application of database systems. In this sense, database systems are an important branch of software research and are often referred to as database fields.

The database system is a kind of ideal data processing core mechanism developed to meet the needs of data processing. The high-speed processing power and mass storage of computers provide the conditions for automating data management. (FYI).

Interpretation of the database.

A collection of reasonably organized data in computer memory that can be used by a computer. This data is rarely duplicated, and the data is stored independently of the program that uses it and can be shared by multiple users.

Word decomposition Explanation of number Number (number) ù Representation, division, or calculated quantity: number is unlucky. Quantity.

Numeral. Number theory (a branch of faith mathematics, which mainly studies the properties of positive integers and the laws related to them). Numerical control.

Few, a few hungry beams: a few people. days.

Skill, academic: "The number of the husband is the number, and the decimal is also". Destiny, day.
