Database Management simply refers to managing data in a database. Database is the back-end of any software system. It stores all the information or data used in the software system or application, after which you can easily search, sort and analyze the data.
We can build a database from the scratch or integrate existing database like, MySQL, SQL etc. Server with your software or site. Our knowledge in the field of web technology and database management system allows us to deliver practical, efficient and manageable solutions to our customers.
We have both skilled database developers and administrators. Our database developer works on database technologies, while a database administrator typically focuses more on routine maintenance and support for your existing database setup.
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 in a database, including record and file structures, date formats, field names and validation rules. A database administrator (DBA) is an instructor of a DBMS, who commands database to make necessary changes of loading, modifying and retrieving existing data.
Some Database Management System are listed below:
- SQL Server
Types of Database
Database is developed as per the user requirements. Different types of database serve different purposes and are different in structure and capability. Some of the databases are as below:
Centralized Database stores the data in fixed centralized location and multiple users can access the data at the same time from different locations. User needs authentication from the system to access the data in a centralized database. The validation and verification measures are also integrated in the system.
Distributed database is just opposite of centralized database and consists of data from the common database and local computers. Data are distributed to other sites within the same station. These sites are connected with each other and communication link between these sites are established. Distributed database can be further categorized into two other categories:
- Homogeneous Database
- Heterogeneous Database
End User Database
An End User Database is a shared kind of database, which collects the information and provides it to the end users. It has nothing to do with transactions or operations, which are executed in various levels. However, it deals with the product, which may be a software or an application.
An Operational Database is a data warehouse that manage and store the data in real time. This database can be either SQL or NoSQL. Elements of the operational database can be added and removed within the seconds. Real time information includes payroll records, employee data or customer information and provides real time operations.
A Relational Database stores data in a set of tables, which consists of rows and columns. The column in the table has an entry of data for the category and rows contain instance of the same data which is defined for the class. This database uses SQL as an application program interface. The Relational Database is one of the most used database category for its functionality of storing structured data in rows and columns.
People nowadays use cloud virtual environment to store data. Clouds are categorized into three categories:
- Hybrid Cloud: A cloud database consists the functionality of both public and private clouds.
- Public Cloud: It is an open database where everyone can access database and retrieve data.
- Private Cloud: In a private cloud database only authorized users can access data.
A Cloud database extends the functionality of almost all other databases as it is well-optimized and maintains a virtual environment in which you can pay per acquired storage capacity and bandwidth used or per user basis. These databases have high availability and scalability.
Object Oriented Database
This database consists of a relational database, which uses the object-oriented programming (OOP) language such as, C++, Java. Various items of this database are created using OOP language, which are then stored in a relational database inside an object-oriented database.
Note: *Those items can be stored in a relational database only but object-oriented database is preferable as it is well organized.
A Commercial Database is subject specific database, which are the paid version of 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. Note: *Single user cannot maintain this large database.
Personal Database stores data and information in a personal computer. Access to personal database is limited to a small group of people inside an organization or a department of an organization. Database management activities of personal database are simple and easy to carry out.
Graph Database plays with nodes, edges and entities. An edge in graph database represents a relationship between objects and these objects are connected to other entities as well. This database is used for mining data and analyzing interconnection.
Survey shows more than 2.5 quin-trillion bytes of data are generated every day. Even in an organization, millions of data are acquired within a single working day. Database developers carry out database management tasks. If you look down from a top of a building, what you will see is data and lots of data. These 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, and cryptographic data is known as database development.
