Information is generated faster than ever. For example, imagine a hospital. Think about all the records that need to be kept on the system for each incoming patient. In addition to the patient's medical records, fees and associated personal information must be maintained. How do you do it? Database management system.
Database management systems are used for a number of reasons. Big Fortune 500 companies use it to get complex and accurate information about every customer. Basically, a good database management system processes, organizes, and stores the data in the system, making information retrieval as simple as possible. In addition, all information is collected in a single system so that everything can be retrieved quickly and easily.
Each database has a specific organizational structure that stores the attributes of the information that can be searched and retrieved in the database. Let's use this general example. Suppose you have a database of different types of shirts in your closet. The size of the shirt can be expressed as small, medium or large. Another feature is shirt colors-red, blue, orange and more.

If you are organized in a database, you can enter commands into the database to get the information you are looking for. Let's say you want to know how many medium blue shirts are in your closet. You can set up the database to search the database for entries that match the blue and center attributes. With the right database, this question can be answered immediately.

This is clearly a very simple example. However, you may own a business and know which customers have spent more than $ 10,000 with you over the past three years, your family has more than two children, and you are over fifty. Imagine searching for all the records in the archive and trying to find them manually.
