Talking about the Application and Development of Database Technology
With the steady advancement of the information construction process, database technology has also been widely used. In this article, we will analyze and discuss the characteristics of the database, the related technologies of the application, and the development trend of the application. 1 The characteristics of the database and its role (1) Data structure. The database realizes the structuring of the overall data, which is one of the main features of the database. It is also the essential difference between a database and a file system. That is to say, considering the data structure of an application, the data structure of the entire organization should also be considered. In the database, not only the data is structured as a whole, but also the way to access the data is flexible, a certain data item, a group of data items, a record or a group of records that can be accessed. In the file system, the access unit of data is a record, and the granularity cannot be as fine as the data item. (2) Data complexity. The complexity of the database is mainly reflected in the data itself and the process of processing the data. First, for modern applications, the amount of data is huge, and the management of this huge amount of data is complicated. Second, the dynamic relationship between data and data leads to the relationship between data. For example, multiple semantics, multiple types, etc. are all dynamic associations, and the relationship between time and space is non-explicitly defined. (3) The data has high sharing, low redundancy and easy expansion. The database views and describes the data from a holistic perspective. The data is no longer oriented to an application but to the entire system, so the data can be shared by multiple users and multiple applications. Data sharing can greatly reduce data redundancy, save storage space and avoid incompatibilities and inconsistencies between data. Since the data is oriented to the whole system, it is structured data, which can be shared not only by multiple applications, but also easier to add new applications, which makes the database flexible and easy to expand to meet the requirements of various users. (4) High data independence. Data independence is a common term and important concept in the database field, including the physical independence of data and the logical independence of data. The data and the program independently separate the definition of the data from the program, and the method of accessing the data is provided by the DBMS, which simplifies the preparation of the application and greatly reduces the maintenance and modification of the application. In summary, a database is a large collection of shared data that is stored in a computer for a long time. The advent of databases has shifted the information system from a process that processes data to a new phase centered around shared data. Database technology has become one of the fastest growing technologies in the computer field. 2 Application status of database technology (1) Application of database technology in web technology. With the continuous development of modern technology, the application of the Web has begun to develop greatly. At the same time, the data resources owned by Web technology are huge, so a huge data resource forms a shared database in the whole world. But at the same time, it faces an integration problem caused by data heterogeneity, and data heterogeneity mainly has three types of effects, namely mode, data type and semantics. (2) Application of database technology in multimedia technology. Compared with the traditional database technology, this kind of database combined with multimedia technology, the advantages of multimedia technology make the data interface rich and fully solve the related technical problems that may be brought about by the combination of the two, the security of related databases Sex has been improved very well. There are many problems in the design of multimedia database that need to be addressed: user interface support, database organization and storage, and the distribution of information on the types of media. (3) Application of database technology in object-oriented aspects. In order to meet the user's application requirements, maintain the security of user data transmission and application, the object-oriented method and technology are gradually integrated into the database. Due to the gradual innovation of database technology, the database has gradually evolved into an object-oriented database, and object-oriented methods and technologies are also being integrated into more complex application systems or software, such as: common computer printing, material demand planning and assistance. Software engineering, etc. 3 Development trend of database technology (1) Application of database technology in the professional field. During the period of continuous research on database technology, new database technologies for professional application fields have been proposed by some foreign professionals. This new database technology is mainly aimed at the user domain to use the technology to meet the user's actual application. The new database technology mainly includes statistical database, engineering database, database applied in insurance industry, scientific database and geodatabase, etc. These new databases with no major changes in the principle realize the organic combination of database technology and professional application field. The practical application support capability of the computer system has been greatly improved. The development of new technologies will inevitably be deepened as the database research work continues. (2) Database technology application of data warehouse and e-commerce. Database is the latest technology in data management and an important branch of computer science. As the core and basic database technology of information system, it has been widely used. Researchers at home and abroad have conducted a lot of in-depth research on data warehouse technology. The researchers combined the application requirements and development direction of database vendors. The development direction of data warehouse and e-commerce. Data warehousing technology has improved the efficiency of data management in telecommunications, finance, taxation and other fields while creating unprecedented economic benefits. Enterprises such as Oracle, IBM, and CA all have the ability to solve large data warehouses, and the data warehouses that are put into use, such as the China Merchants Bank system. Many researchers have great expectations for the future of e-commerce and database integration. This new concept has been greatly developed with the development of the Internet. In summary, with the explosion of information resources, the development of various database technologies has become an inevitable trend. Under the complemented relationship, the development of database technology has also gained effective and powerful momentum. Under the impetus, database application technology will certainly develop towards a more scalable and intelligent direction, in line with the pace of social science development.
