Database Management

blog

Database Management simply refers to managing data in a database. The 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 databases 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 the database to make necessary changes of loading, modifying, and retrieving existing data.

Some Database Management System is listed below:

  • MySQL
  • SQL Server
  • dBase
  • Oracle
  • FoxPro

Types of Database

The database is developed as per the user requirements. Different types of databases serve different purposes and are different in structure and capability. Some of the databases are as below:

Centralized Database

Centralized Database stores the data in a fixed centralized location and multiple users can access the data at the same time from different locations. The user needs authentication from the system to access the data in a centralized database. The validation and verification measures are also integrated into the system.

Distributed Database

A distributed database is just the opposite of a 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 links between these sites are established. A 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 information and provides it to the end-users. It has nothing to do with transactions or operations, which are executed at various levels. However, it deals with the product, which may be software or an application.

Operational Database

An Operational Database is a data warehouse that manages and stores 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.

Relational Database

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 instances 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 categories for its functionality of storing structured data in rows and columns.

Cloud Database

People nowadays use cloud virtual environments to store data. Clouds are categorized into three categories:

  • Hybrid Cloud: A cloud database consists of the functionality of both public and private clouds.
  • Public Cloud: It is an open database where everyone can access the 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 is then stored in a relational database inside an object-oriented database.

Note: *Those items can be stored in a relational database only but an object-oriented database is preferable as it is well organized.

Commercial Database

A Commercial Database is a subject-specific database, which is 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 through commercial links. Note: *Single users cannot maintain this large database.

Personal Database

Personal Database stores data and information on a personal computer. Access to a personal database is limited to a small group of people inside an organization or a department of an organization. Database management activities of a personal database are simple and easy to carry out.

Graph Database

Graph Database plays with nodes, edges, and entities. An edge in a 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.

Database Development

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 the top of a building, what you will see is data and lots of data. These data need to be organized in a database and the development of a database that would store different kinds of data like, images, videos, photos, texts, and cryptographic data is known as database development.

 

In Nepal, there are less fewer database development companies. However, Podamibe gives assurance to provide the best and user-required database management as well as provides development services all over Nepal.  A database developer is responsible for:

  • Designing and developing a new database.
  • Editing and modifying the existing database.
  • Database management, fixing database issues and errors.

Database Development Life Cycle

A database management and development process go through lots of steps and testing in each step. A typical database life cycle consists of the following steps:

  1. Feasibility Study
  2. Requirement Analysis
  3. Database Designing: A database design consists of three phases: Conceptual Database Design, Logical Database Design, and Physical Database Design.
  4. Application Design
  5. Implementation
  6. Loading of Data
  7. Testing
  8. Maintenance
