What is Database

Data bases

A database is a methodical meeting of information. They support electrical storage and manipulation of data. Databases make it easier data Management.

Consider an example of a database: an online phone book uses a database to store data about people, phone numbers, and other contact information. Your electrical service provider uses a database to manage bills, and customer issues, collect outage data, and more.

Also consider Facebook. It should store, manipulate and present data related to members, their friends, member activities, messages, advertisements and much more. We can provide countless examples of database usage.

What’s the change between a database and a spreadsheet?

Databases and worksheets (such as Microsoft Excel) are convenient ways to store information. The main differences between the two are:

  • How data is store and manipulated
  • Who can access the data
  • How much data can be stored

Spreadsheets were originally designed for a single user, and their functionality reflects that. They are perfect for a single user or a small number of users who don’t need to handle incredibly complicated data.

Databases, on the other hand, are designe to hold much larger collections of organized information, massive amounts sometimes. Databases agree multiple users at the same time to access and query data quickly and securely using very complex logic and language.

Types of Databases

Here are some popular types of databases

Distributed databases

A distributed database is a type of folder that has contributions from common database and information captured by local computers. In this kind of database system, the data is not in the same place and is distributed among several establishments.

Relational databases

This type of database defines the members of the family of databases in the form of tables. It is also called relational DBMS, which is the most popular type of DBMS in the market. The sample RDBMS system database includes. MySQL, Oracle and Microsoft SQL Server databases.

Object-oriented databases

This type of computer database takes charge of storing all kinds of data. Data is store as objects. Objects to be kept in the database have attributes and methods that define what to do with the data. PostgreSQL is an example of an object-oriented relational DBMS.

Centralized database

This is a centralized location and users from different backgrounds can access this data. These types of computer databases store application procedures that help users access data even remotely.

Cloud databases

A database in cloud is a database optimize or design for this kind of virtualize environment. A cloud database has many advantages, some of which could pay for storage capacity and bandwidth. It also offers on-demand scalability, as well as excessive availability.

There are three main components of a database


Hardware consists of electronic physical devices such as computers, I/O devices, storage devices, and many more. This offers the Interface between computers and real-world systems.


It is a collection of programs use to manage and control general database angels. This includes the database software itself, the operating system, the rose software use to share data between users, and the utility programs to access data.


However, unorganized fact that requires processing to be meaningful. Data can be simple to once disorganized unless organized. Generally, data includes facts, observations, perceptions, numbers, characters, symbols, pictures, and many others.

What is a Database Management System (DBMS)?

The Database Management System (DBMS) is a collection of programs that allow its users to access databases, operate data, report, and represent data. It also benefits to control access to the angels folder. Database management systems are not a new idea and as testimonials, they were first implemented in 1960s.

Charles Bachman’s Integrated Data Store (IDS) is said to be the first DBMS in history. With the time database, technologies have evolved a lot, while the use and expected functionalities of databases have increase enormously.

Advantages of DBMS

  • The DBMS offers a variety of strategies for storing and retrieving data.
  • The DBMS serves as an efficient controller to balance the needs of multiple programs that use the same data.
  • Uniform data management procedures.
  • Package programmers are never expose to the details of data storage and representation.
  • A DBMS uses several powerful functions to efficiently store and retrieve data.
  • Offers data security and integrity.
  • The DBMS involves integrity constraints to obtain a high level of security against unauthorized access to data.
  • A DBMS schedules concurrent access to data so that only one user can access the same data at the same time.
  • Reduced application development time.

Disadvantage of DBMS

DBMS may offer plenty of advantages then, it has certain flaws.

  • The hardware and software cost of a DBMS is quite high, which adds to the budget of your business enterprise.
  • Most database management systems are often complex systems, so training is require for users to use the DBMS.
  • In some companies, all the data is integrate into a single which may get damage due to power failure or the database gets corrupted on the storage medium.
  • Simultaneous use of the same program by many users sometimes results in loss of Certain Data.
  • The DBMS cannot perform sophisticated calculations.


With the help of databases and other BI tools and IT tools, facility professionals can use organized data to facilitate the improved and efficient decision making, angels of agility and angels of scalability. The different types of databases, as well as changes in technological approaches, advances in .Automation and the cloud are pushing databases into new directions.
