What is SQL injection?SQL injection is a code injection technique that used to attack data-driven applications such as injecting malicious SQL code into specific fields for the implementation of a drag-and-drop attack. The success of SQL injection must be the result of an application's security vulnerability, such as when user input is not properly filtered (for

Label:Not all databases are so complex that they require the use of expensive database management systems and enterprise-class hardware. Some databases are actually very small enough to run on an old-fashioned PC. All databases are not the same. They have their own different needs and different challenges.

Oracle databases are usually the first choice for large databases and large enterprises for the stability, high availability, cross-platform and massive database processing. Despite this, many small and medium-sized enterprises still want to taste Oracle, so there are also many small and medium databases in the Oracle environment. For cost consideration, it is us

As computer technology is increasingly widely used in various fields of the national economy, while computer hardware is constantly miniaturization, application systems are evolving towards a more complex and large-scale direction. Database is the core of the entire system. Its design is directly related to the efficiency of system execution and system stability. Therefore, in software system development, database design should follow the necessary database Paradigm Theory to reduce redundancy a

Currently, commercial database management systems are dominated by relational databases, with mature technologies. Although the object-oriented database management system is advanced in technology and easy to develop and maintain, there are no mature products yet. Leading relational database management systems at home and abroad include Oracle, Sybase, Informix, and INGRES. These products support multiple platforms, such as UNIX, VMS, and windows, but
