Analysis of 3000-word database programming and database storage technology.
With the development of information technology and the progress of human civilization, data processing has been paid more and more attention in the development of computer-related technologies. In different development periods, according to different computer types and different practical applications, the requirements for database programming and data storage technology are also different, which need to be analyzed in detail according to the actual situation. This paper analyzes the related technologies.

introduce
In the process of computer development, it is very important to edit programs according to the data and programs stored in the computer. Although there are differences in the specific operation process according to different computers, we can find that it is not difficult to achieve good results as long as the corresponding programs of the database are edited in the data storage, so it is not difficult to study the technologies related to database programming and database storage, which can replace the work of real people and achieve good results.
With the popularization and application of computers, computer application software has developed rapidly. In a sense, the reason why computers can be used in various fields is largely due to the corresponding application software. Software companies have developed targeted application software according to the characteristics of various industries. Through the use of these softwares, it can bring convenience to practical work and improve work efficiency. For example, industrial automation, now computer technology has a certain degree of intelligence, can replace people to operate. The probability of error in this way is very low, the computer does not need to rest, and the production efficiency has been greatly improved. In computer software, especially some large-scale software, database is the core content of software. Therefore, in the process of computer software writing, database programming and storage technology is also a core content, which is influenced by special historical reasons in China. Therefore, the development of software industry in China is slow, so database programming and storage technology is the core content.
1, Introduction to Database Storage Technology
1. 1 the concept of database storage technology
The development of database depends largely on the improvement of computer performance. In the early days of computers, there was no concept of database. At that time, the computer's performance was very low, and it could only perform some simple digital operations. The volume is also very large, and there is no concept of data storage. With the application of transistors and integrated circuits in computer manufacturing, the performance of computers has been greatly improved and has been applied in various fields. When computers are used for data management, especially for some complex data, traditional storage methods can no longer meet people's needs. Under this background, DSMS was born. At that time, this database management system was a revolution of database management technology. With the improvement of computer performance, SQL, Oracle, etc. Gradually appear. In traditional database programming, different programming languages are used due to different periods of database writing. At present, commonly used softwares include VB, JAVA, VC and C++. With these programming software, you can write the specified database. Because each software has its own characteristics, the chosen programming software industry is different in different fields of data programming.
Development of 1.2 database storage technology
The concept of database can be traced back to 1950s at the earliest, but the management of database at that time was still in the traditional manual way, without the form of software, so it can't be regarded as the origin of database storage technology. In the mid-1960s, with the appearance of computer storage devices, computers were able to store data. In this context, data management software was born, but limited by the technical conditions at that time, it can only be based on files. Storing data in external storage devices, people have developed operating systems with interfaces for managing stored data. With the popularization and application of computers, computers can store more and more data, and people's requirements for database storage technology are getting higher and higher, especially the increase of enterprise users. I hope that the database storage technology has a high enjoyment ability, and the data storage technology has made great progress in this period. The current database storage technology is also developed according to the standards of this period to a great extent. With the development of database itself, many new database storage technologies have emerged, such as data stream and Web data management.
1.3 Functions of database storage technology
The appearance of database storage technology has a revolutionary impact on the traditional paper storage technology. Because the data is stored in paper, it is easily affected by disasters such as water and fire, resulting in data loss. Since the beginning of human civilization, a lot of historical information has been recorded, but with the passage of time, a lot of data have been destroyed, which has caused serious losses to human civilization, and database storage technology can avoid this problem well. In the database environment, information will be converted into electronic mode and stored in the computer's hard disk. For hard disk storage, it is much simpler than paper books, and the requirements for the environment are relatively low. Some of the latest server memories even have fireproof performance, and the data in the database can be easily copied by computers. At present, many enterprise databases will establish a mirror database, and regularly back up the information in the database to ensure data security to the greatest extent.
2. The relationship between database programming and database storage technology.
2. 1 Database programming determines the type of database storage.
By analyzing the characteristics of computer software, we can know that any software that wants to have related functions needs to be realized in the programming process, and so does the database program. In the process of database programming, the type of database storage can be determined. According to different application fields, database storage technology is also different. For example, in the fields of electric power and traffic control, most applications are real-time databases, but online video websites. Most of them use relational databases, followed by commercial databases, free databases and micro-databases. Each database seems to meet the needs of practical applications. Although a database has become the mainstream in different historical periods, it is difficult for database programmers to compile these databases. There is not much difference. Although different programmers, due to different education and habits, use different programming software in the actual writing process, but whether VB, VF or C++, they can write every database type. In a sense, the determination of database type is usually designed in the software requirements analysis stage, and then realized in the data programming stage.
2.2 Database storage technology is the core of database programming.
For database programs, the most important function is to store data. Usually, a database program is divided into several modules, and the core module is database storage technology.

Under the current situation of domestic economic development, the form of computer-oriented software industry has also become a key industry under the vigorous promotion. With the development of the industry, related programs to promote simple work have also been researched and invented. Even for ordinary users without computer expertise, it is acceptable to use or develop programs, but it is limited to database programming and database storage technology. But as the core area of the system, related technologies are also very important. Therefore, in order to improve work efficiency and relieve work pressure, it is necessary to choose the most advantageous corresponding software processing technology within the application scope, and take this as the research and development center to develop the required software types and do all the data sorting work, which is very important for the promotion of office and the database programming technology in data storage.
