With the development of information technology, the database of two-dimensional table structure has not been able to save a large number of multimedia non-structured complex data, and the relationship between various data. Relational databases need to be broken. The choice of information technology platform is often a key issue when establishing or re-establishing an application system, and the database is a key platform that needs to be made. The relational database management system has been in technology mainstream, but this traditional database management system is inherently constrained and restrictions. It is difficult to adapt to the rapid business needs, as well as new technologies. The limitations of relational databases have the rapid development of information technology, but also data processing is not only larger, but also requires increasingly high quality. The data managed by the database has undergone fundamental changes. This change has brought a huge challenge to database technology. The object of database management is no longer limited to a simple data type such as text data, and a large number of multimedia non-structural complex data is required, and the relationship between data is required. In addition, as the number of hot website visits, the storage mechanism of the database itself, a large number of concurrent users, the use efficiency of the storage space, and the integrity and security of the data are put forward. These are not in the traditional database, and the simple structure of the two-dimensional table can be used. The relational database is based on whether the data is expressed as a simple two-dimensional model, that is, the record of the row and column is stored. Obviously, due to the limitations of the conditions, it is only a technique suitable for simple data storage processing, there is a limit to overcome. The relationship database management system itself is inherently limited, and the two-dimensional table data model used in the data model is not effectively handled in most transaction applications on most transaction applications. data. Its inevitable results is that in a complex mode, the number of interactions has increased, and the model of simulating realistic data relationship is not well provided. Due to many data models used, it is also possible to cause massive increase and a lot of waste of storage space, and will result in a decline in the response performance of the system. Moreover, in real data, there are many types of types that do not have better handling. Performance is limited to static applications such as report generation, and the relational database management system designed, does not have optimized processes for efficient transaction processing. As a result, it is often some relational database products that do not meet the expected results during the transaction processing of GUI and WEB. This does not fundamentally solve the problem unless more hardware investment is added. Use the two-dimensional table data model of the relational database to handle typical cobots in most transaction applications, but their results are often established and use a large number of data forms, which is still difficult to establish data models that use the actual world. And when the data needs to be reported, it is necessary to find a large number of two-dimensional data tables that have been dispersed, and the index is used to find all the required data, which is bound to affect The response speed of the application system. Restrictions on extended scalability are restricted in effectively supporting applications and data complexity. The standardized design method of the relationship database is based on the design and performance optimization of complex transactions, and performance optimization. In addition, high development and maintenance costs also make companies unbearable. In addition, the retrieval strategy of relational databases, such as composite indexes and concurrent locking technologies, will cause complexity and limitations in use. The rear relational database proceeds to the development of information technology, and there is still many capability limits in the process of processing complex data types, complex data relationships, and multiple access methods with relational database data models.
