It collects all the information used in the software system or application, after which you can easily search, sort and analyze the data.

What is Database Management?
Database Management is a process of defining, manipulating, retrieving and managing data in a database. A Database Management System (DBMS) is integrated to automatically manipulate data itself inside a database including date formats, record & file structures, field names and validates rules. A database administrator (DBA) is an instructor of a DBMS which commands databases to make necessary changes of loading, modifying and retrieving existing data.
Some Database Management Systems are:
- SQL Server
Types of Databases
Databases are developed according to the user requirements. Different types of databases serve different purposes and are different in structure & capability. Some of the most used databases are as:
In this database, the data is stored in a fixed centralized location and multiple users can access data at the same time from different locations. People can access data stored in a centralized database but need authentication first to do so. Validation & verification measures are integrated in the system.
Distributed databases are just opposite of centralized database in which consists of data from the common databases and local computers. Data is distributed to various other sites within the same station. These sites are connected with each other and communication between these sites is established. Distributed databases can be further categorized into two other categories of homogeneous & heterogeneous databases.
End User Database
End user database is a shared kind of database which collects summaries of information and provides it to end users. It has nothing to do with transactions or operations which are executed in various levels and is concerns with the product which may be a software or an application.
Operational databases manage data in real time. It is like a data warehouse which store data in the instant. Operational database can be either SQL or NoSQL and elements on an operational database can be added and removed within seconds. Real time information includes payroll records, employee data or customer information and provides real time operations.
Relational database stores data in a set of tables which consists of rows and columns. The column in the table has an entry for data for a category and rows contains instance for that data defined for the category. Relational databases use SQL as an application program interface. Relational databases one of the most used database category because of its structured data storing in rows and columns functionality.
People nowadays use clouds AKA virtual environments to store data. Clouds are categorized in 3 categories:
- Hybrid Cloud: A cloud database consisting functionality of both public and private clouds.
- Public Cloud: A public database where everyone can access database and retrieve data.
- Private Cloud: In a private cloud database only authorized users can access data
Cloud database extends functionality of almost all other database as it is well optimized and maintains a virtual environment in which you can pay per acquired storage capacity and bandwidth used or per use basis. These databases have high availability and provide scalability.
Object Oriented Databases
These databases consist of relational database and use of object-oriented programming languages such as C++, Java. Various items of these database are created using OOP language which are then stored in a relational database inside an object-oriented database. Those items can also be stored only in a relational database but object-oriented database is more suitable as it is well organized.
Commercial databases are subject specific database which are the paid version of the huge database created for users who access database information for help. These databases are maintained by upper level managers and access to these databases is provided only though commercial links. These are large databases and one only cannot maintain such huge information.
Personal database stores data and information on a personal computer. Personal database are small and easy to manage. Access to personal database is limited to small group of people inside an organization or a department of an organization. Database management activities of personal databases are easy to carry out.
Graph Database plays with nodes, edges and entities. An edge in graph database represents a relationship between entities and these entities can be connected to other entities as well. These databases are used for mining data and analyzing interconnection.
Survey shows more than 2.5 quin-trillion bytes of data is generated every day. Even in an organization millions of data is acquired within a single working day. Database developers carries out database management tasks & help harness this data and its power. If you look down from a top of a building what you will see is data & a lot of data. This data needs to be organized in a database and development of a database that would store different kinds of data like images, videos, photos, texts, cryptographic data and more is known as database development.
