Database management system (DBMS) and information management systems (MIS) As everyone knows, the database is logically related data elements of the pool, these data elements may be different from the structure of organizations, units and indivials to meet a variety of processing and retrieval needs. The database itself is nothing new - Early in the database chisel on stone, recorded on the roster, and write in the index card. Now, generally recorded in the database can be magnetized on the media, and the need to use a computer program to implement the necessary storage and retrieval operation. As described below, all the databases (except for the simplest) has complicated relations between the data and its link. Processing and create, access and maintenance of database records related to the complex task of system software package called the database management system (DBMS). DBMS package that the proceres in its database to establish user interface. (Application of these users are programmers, administrators, and other information needs of the various operating systems and proceres). DBMS can be organized to deal with and that the elected from the database data elements. This allows policy-makers can search, detect and query the content of the database, thus not in the formal report, no longer appears and can not be expected to answer the question. These problems may initially vague and (or) the definition is not appropriate, but until people can browse the database to obtain the necessary information. In short, DBMS will be "management" of stored data, from public databases and pooling of data required for non-programmers to answer questions. In the paper-oriented system, specific information needs of users they should be sent to the requirements of programmers. The programmers in the time allowed, will prepare one or more proceres to extract the data and preparing information. However, DBMS the availability to provide users with a faster alternative communications channel. Management Information System (MIS) concept has been defined by the dozens. MIS because the organization model may vary, so MIS with the application of the definition of the scope and breadth of change is not strange. This article, MIS system can be defined as computer-based data processing network system, it is a body in order to support decision-making and other management functions necessary to provide timely and effective development of the information, and may need to combine the process of artificial and other Together. Although the MIS model different, but most of which are recognized as shown concept. In addition to the map shown in the horizontal management structure named, a body from the vertical may also need independent information flow into the different functional departments. Horizontally integrated management level have a long vertical as shown the complex organizational structure. This structure is based on the database, which is by the way the internal and external, with the past, present and foreseeable future events related to the composition of the data. MIS designers of a knotty problem is to develop support for decision-making flow of information. Generally speaking, the different levels with different responsibilities of managers from most of the information needed to existing information systems (or subsystems) of the pool, these systems in MIS can be closer together, but the situation is more often loose Coupled. SQI and SQL Server IBM in the 1970s, the design of a dedicated computer database query language SEQUEL, these letters is structured query language acronym in English. With the passage of time, he added many features, is not only a query language, can also create a database management database engine safety. IBM to its public offering, then became the now as you know SQL. Due to historical reasons SQL can be read into a sequel, can also case-by-field Pincheng SQL. In the present database engine, have a good variety of SQL version. Microsoft SQL server using the T-SQL, it represents the affairs of SQL. 1. What is the SQL server? SQL server is a client-server relational database management system (DBMS), the use of its services in SQL Server and SQL client to transfer request. 2. Client - server architecture Term client, server and client - the server can be very broad or refers specifically to the concept of hardware and software. According to the general concept of client systems from other parts of the requested services or resources of any system components; server to the other system components provide services or resources of any components. For example, when users on the network workstations from printing a document, the client workstations, using false offline printing machines are servers. Based on data of any client, server system by the following components. Server - data of the object and support the pool, these objects are organized and ready to submit to the search for data, classification and reorganization, retrieval, updating and analysis of such services to facilitate. Data from the database of physical memory and database services component. All the data access through the servers, not all clients direct access to physical data. Client - a software program, the program should be interactive personal use or may be an automatic process. Including the request for data from the database, or send data to the database server and so the use of interactive software, such as management utility (which is part of SQL server procts and sold separately), in particular query and reporting software, customer applications, spot applications WEB-based proceres and server applications. Between the client and server communications - client and server communications between the largely depends on the client and server is how to achieve it. The physical layer and communication logic may be the same. When you use a person and telephone communications, the telephone system is the physical layer, which stresses the natural language communication is the logic layer. Based on data for the system, if the server and client in different computers, the physical layer can be a network. If the server and client on the same computer, communication between the process can be. Physical layer logic communication structure can be called low-level operating system, a dedicated data access language or open structured query language (SQL). 3. SQL server platform SQL servers running on the operating system as shown. SQL server seventh edition server software only runs on 32 for the API based on the Windows operating system, but can use the operating system platforms want to create and implement customer applications.Database management system (DBMS) and information management systems (MIS) As everyone knows, the database is logically related data elements of the pool, these data elements may be different from the structure of organizations, units and indivials to meet a variety of processing and retrieval needs.
