In doing so, they can even index the data from numerous tables consisting of rows and columns. This makes data-querying efficient and straightforward. According to their functions, databases generally fall into the following categories:

  • An object-oriented database where information within itis represented in the form of objects,
  • Relational database which organizes the data into specific tables which are interlinked to each other,
  • Distribute where the information is stored in a series of databases in multiple computers but appear to the end-users as one,
  • A hierarchical database is one which organizes and showcases the information it contains in a tree-like structure, and
  • A network database is an extension of the hierarchical model whereby users can link multiple records to the same owners’ file

Companies need databases to store sensitive information in records that maintain complex logical relationships with relevant datasets. These datasets increase exponentially as they expand their business operations in the market.

Companies soon realize the need to operate a software solution that is capable of managing their databases. It should be able to organize, maintain efficiently, and process all of the information which databases contain. This is where a database management system comes into the picture.

Definition of a database management system (DBMS)

A database management system (DBMS) is a software application that creates, manages, accesses and optimizes information in a database. It collects, stores organize, safeguards verifies, and system processes data.

The program makes it easier for companies to accumulate, update, modify, retrieve, or delete necessary information. It also performs other essential functions, such as performance tuning, monitoring, backup, and data recovery. The vital components of any database management system are as follows:

  • The software program connects the operating system to hardware components and acts as an interface for the end-users,
  • The data consists of records, index files, and directories showing the relationship between various data types,
  • Procedures refer to the instructions that help the end-users create, modify, and manage and process the database,
  • Database language allows end-users to conduct various operations on databases like access, update, modify, execute or retrieve data,
  • Query processor functions as an intermediary between end-users and the database engine to execute various query commands,
  • The runtime manager verifies user authorization to run queries, processes the commands and formulates an optimal strategy for efficient execution,
  • The database manager is responsible for permitting the execution of query commands to perform different operations,
  • The data engine is the vital part of the software application which carries out the core activities of storing and retrieving data, and
  • The report generator displaces critical information on DBMS files, their structure, and format based on particular specifications.

Importance of database management systems for companies

The importance of installing and operating suitable database management systems for companies are as follows:
