In the current informatization age, both individuals and enterprises pay great attention to management informatization. This development trend further promotes the widespread use of database technology. In terms of management informatization, database technology has multi-level advantages and strong adaptability in information management. Databases have been widely used in multiple fields, and the technology has developed very rapidly. However, at the same time of development, we should also pay attention to improve the security of database technology. In the practical application of the database, the security of the database has always been a problem of the public, and the theoretical processing of the database needs to be closely combined with practice. Only in this way can we promote the sustainable development of database technology.
