Research And Application Of Key Technologies In Distributed Database

Most companies are faced with tough decisions when considering which database technology to use when intending to integrate their organization’s database, because of the variety of the functionality of different databases and the cost related factors.The main aim of this project is to determine the way of creating a database using My SQL by identifying different type of data and how well to create data tables using different types of data. In this project I will analyze key technologies of distributed database system. Among the key technologies we will focus on My SQL database replication and ?le encryption based on distributed database. Furthermore one will learn how to normalize a database by implementing indexes and referential integrity in a database. But before the development of My SQL there are certain regulations that has to be followed by the developer.Replication is considered to be the operation of copying and maintaining the objects of the multiple databases belongs to a distributed system. The architecture of this kind of system is based around series of delivery servers that reports back to the central database. The farms can be further scaled by adding more severs.The traditional method is to use the super computer system to work out the calculation task. But it costs too much, and the availability and scalability is not strong enough. Therefore, high performance and high availability database system has become the focus in the ?eld of computer science.
