A database management system, also referred to as a database management application, is a software application or a group of related applications which are used to maintain a database in real-time. The term database management is used to describe the procedures followed to back up, restore, retain, search and remove all information from any database, including the central database of an enterprise. Database management systems are designed to optimize the available database management resources and to provide effective database management services. Database management systems help organizations effectively deal with critical data requirements and support data-intensive business functions. They are designed to store, protect, and support databases, which are vital for various business applications.
Flat file and relational databases
There are two types of databases: flat file databases and relational databases. Flat file databases are more efficient and space-saving than the relational variety. On the other hand, the relational database structure is quite complex and expensive. A business organization usually deploys both flat and relational databases. Data storage is done in a variety of ways: on-site data storage systems, off-site data storage systems, internet-based data storage systems and mobile device data storage.
Benefits of using a DBMS
There are many benefits of using a well-designed DBMS. Apart from providing high levels of data access speed and reliability, a good DBMS will facilitate data security. Installing a custom database server is cost-effective and time-saving. It ensures quick and easy access to databases. Different types of databases are now used, such as general-purpose, object-oriented and hybrid databases.
General-purpose and object-oriented databases
General-Purpose databases are simple and basic structures, which can be customized according to the needs of the organization. These databases are usually stored on a micro level, on the hardware devices alone. On the other hand, object-oriented databases are highly structured and specialized databases, which store their data in objects. These objects may be used in different applications and can also be accessed directly from the program.
The benefits of object-oriented database management software are obvious. These systems allow for the easy application of complicated business logic and the integration of various different types of data. Objects can be read without any modification, and modifications can be made only by using the correct procedural syntax. Moreover, object-oriented database management systems have the ability to provide for the safekeeping of transaction history, which provides peace of mind to the business owner.
Different aspects of database management software must be considered when choosing the right tool for the organization. The availability of several users and the number of users accessing the same database should be taken into consideration. The cost of running the application should also be taken into account, especially if it is being used by several users at the same time. The right tool should, therefore, be selected based on the size of the company, its dependence on external resources, and the kind of data integration required.
