DBMS

Cost of Hardware and Software:  It requires a high speed of data processor and large memory size to run DBMS software. Size:  It occupies a large space of disks and large memory to run them efficiently. Complexity:  Database system creates additional complexity and requirements. Higher impact of failure:  Failure is highly impacted the database because in most of the organization, all the data stored in a single database and if the database is damaged due to electric failure or database corruption then the data may be lost forever.

Controls database redundancy:  It can control data redundancy because it stores all the data in one single database file and that recorded data is placed in the database. Data sharing:  In DBMS, the authorized users of an organization can share the data among multiple users. Easily Maintenance:  It can be easily maintainable due to the centralized nature of the database system. Reduce time:  It reduces development time and maintenance need. Backup:  It provides backup and recovery subsystems which create automatic backup of data from hardware and software failures and restores the data if required. multiple user interface:  It provides different types of user interfaces like graphical user interfaces, application program interfaces

It uses a digital repository established on a server to store and manage the information. It can provide a clear and logical view of the process that manipulates data. DBMS contains automatic backup and recovery procedures. It contains ACID properties which maintain data in a healthy state in case of failure. It can reduce the complex relationship between data. It is used to support manipulation and processing of data. It is used to provide security of data. It can view the database from different viewpoints according to the requirements of the user.

Database management system is a software which is used to manage the database. For example: MySQL, Oracle, etc are a very popular commercial database which is used in different applications. DBMS provides an interface to perform various operations like database creation, storing data in it, updating data, creating a table in the database and a lot more. It provides protection and security to the database. In the case of multiple users, it also maintains data consistency.

One way to classify databases involves the type of their contents, for example:  bibliographic , document-text, statistical, or multimedia objects. Another way is by their application area, for example: accounting, music compositions, movies, banking, manufacturing, or insurance. A third way is by some technical aspect, such as the database structure or interface type. This section lists a few of the adjectives used to characterize different kinds of databases. An  in-memory database  is a database that primarily resides in  main memory , but is typically backed-up by non-volatile computer data storage. Main memory databases are faster than disk databases, and so are often used where response time is critical, such as in telecommunications network equipment. An  active database  includes an event-driven architecture which can respond to conditions both inside and outside the database. Possible uses include security monitoring, alerting, statistics gath...

Formally, a "database" refers to a set of related data and the way it is organized. Access to this data is usually provided by a "database management system" (DBMS) consisting of an integrated set of computer software that allows  users  to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data). The DBMS provides various functions that allow entry, storage and retrieval of large quantities of information and provides ways to manage how that information is organized. Because of the close relationship between them, the term "database" is often used casually to refer to both a database and the DBMS used to manipulate it. Outside the world of professional  information technology , the term  database  is often used to refer to any collection of related data (such as a  spreadsheet  or a card index) as size and usage requirements typical...
