We can simply say that data here is maintained on the centralized server. Based on the sites over which network is distributedĬentralized database system – The DBMS and database are stored at the single site that is used by several other systems too. So in such case, we can integrate and even though database resides in only one place both the departments will have the access to it.
For example the library department and the fee section department should have information about student’s database. It must be accessible to all the departments related to him. For example a student in the college should have the database containing his information. Data can be both integrated and shared,a database should be integrated when the same information is not need be recorded in two places. Multiple users – It supports multiple users concurrently. The user may design, maintain and write the database programs. It is mostly used with the personal computer on which the data resides accessible to a single person. Single user – As the name itself indicates it can support only one user at a time. Examples are CA-IDMS(COMPUTER associates), IMAGE(HP). They are similar to hierarchical database, they look like a cobweb or interconnected network of records. If there are more connections, then this database is efficient. Network database – Mainly used on a large digital computers. Examples are IMS(IBM), Windows registry(Microsoft). They are used in industry on mainframe platforms.

Examples are ObjectDB (ObjectDB software).

It requires less code, use more natural data and also code bases are easy to maintain. It adds the database functionality to object programming languages. Object oriented database – The information here is in the form of the object as used in object oriented programming. Few examples are MYSQL(Oracle, open source), Oracle database (Oracle), Microsoft SQL server(Microsoft) and DB2(IBM). The tables or the files with the data are called as relations that help in designating the row or record, and columns are referred to attributes or fields.

It is customizable, so it allows programmers to modify the MySQL software to fit their specific environments and requirements. MySQL works very quickly and works well even with large data sets. It works with many languages including PHP, PERL, C, C++, JAVA, etc. Furthermore, it provides built-in replication support. MySQL is a free and open source relational database management system and provides support for cross-platforms. It is suitable to use for small as well as for big and complex web applications. MySQL open source DBMS is used as the database for the development of web-based, desktop-based and mobile applications.
