A database management system (DBMS) is computer software designed to help users organize and manage data stored in a database. A DBMS enables users to create databases; add data or documents to those databases; query the databases using search criteria; filter the results based on those criteria; and so forth.
In this article, you will learn more about the ten favorite Database Management Systems, their features and functions.

Microsoft Access is a database software package produced by Microsoft. A relational database management system runs on MS-DOS, Linux OS, Windows, and Macintosh.
Microsoft Access is an ideal tool for small businesses, entrepreneurs, inventors and hobbyists looking for a powerful data management system to help manage their business records.
MS Access as an effective tool for any type of organization including government agencies, schools and colleges, non-profit organizations and small businesses.
Types of Database Management Systems
- Relational Database Management System (RDBMS)
This type of system is mainly used for large businesses or organizations that need to store and manage a lot of data.
It is known as a “relational” system because it uses relationships between tables to store data, which results in a very efficient way to retrieve information from these tables. Examples include MySQL, Microsoft SQL Server and Oracle.
- Object-oriented database management system (OODBMS)
This type of database management system uses objects and attributes to store data in tables. An object is an entity or concept, such as an employee or product that has attributes associated with it. Example include PostgreSQL.
- Network database management system (NDBMS)
NDBMS is a software that manages a network database. It is used to provide centralised database administration, security and control of all databases on a network. The main functions of an NDBMS are:
- The ability to store and manage data in a centralised location with ease of access by users from anywhere in the network.
- The ability to monitor and maintain information on user access rights, server performance and hardware specifications.
- The ability to centrally administer user accounts and privileges for each database.
- The ability for multiple users to collaborate on specific tasks using shared resources such as printers or files.
- Hierarchical database management system
Hierarchical databases use a tree structure where you organize your data by groupings like categories and years. Hierarchical databases also have relationships between different levels of the tree structure.
For example, if you have a department within a company, you can have an employee who is part of that department as well as other employees who may be working on projects that involve the department’s employees.
The Functions of Database Management Systems
- Data storage
Data storage is one of the most important functions of DBMS. This is to store data in such a way that they can be accessed and processed by users. Some databases allow you to store different types of data, e.g., numeric, text, and so on.
- Data retrieval
You can access your stored data using database management systems. For example, if you have entered a value in a database table, you can use the database management system to retrieve it from the database.
- Data manipulation
When users want to perform operations on your stored data e.g., add new records or delete existing records, they need to use the database management system to manipulate them accordingly.
- Data security
A database management system ensures that data is secure. There are several ways to do this, including using passwords, encryption, and creating user permissions.
- Data transformation and presentation
Data transformation is the process of converting data from one form to another. Data presentation is how this data is presented to the user. The two concepts are closely related and can be seen as two sides of the same coin. Data transformation is required whenever there is a need for conversion of data from one format to another. Data presentation depends on how that data should be presented or displayed to the user.
Data transformation is an important part of any database system because it allows users to access their data in various formats from many different sources.
- Data integrity
Data integrity management is one of the key functions of a data management system. The data integrity process ensures that all the data stored in the database are accurate and up-to-date. It involves ensuring that the data entered into the system is correct at all times and does not contain errors or omissions.
Data integrity management helps prevent loss of data or corruption due to changes in data during processing, storage, or transmission. It also helps prevent unauthorized access to your system by hackers and other criminals who may try to steal your confidential information from this system.
- Data Backup and Recovery
The backup process is a critical step in the life cycle of an organization’s data. The goal is to be able to restore the entire database at a moment’s notice and do it quickly. Backing up databases is often done manually, but some organizations use automated tools.
Recovery is the process of restoring data from backups. In most cases, the backup process deletes all of the data in the database, which means that if you want to recover your data after a disaster, you’ll have to recreate it from scratch.
Benefits of Database Management Systems
Here are some of the benefits of using database management systems:
- Improved security
The best database management software comes with built-in security features that help to protect your data from unauthorized access and prevent data loss. This is especially true when the information stored in databases is sensitive or confidential.
- Increased productivity
Database management software can help you to manage more tasks at one time and make your workday more efficient, which means that you will be able to complete more tasks within a shorter period.
- Reduced costs
With the help of database management software, you will be able to save money on operating costs by reducing the number of resources required by each department or team; this includes servers, servers, applications, etc., which can be costly to operate over time because they require ongoing maintenance and upgrade fees as well as costly.
- Streamlined Workflow
Database management software helps streamline your workflow by creating a central control point for all your data. You can keep track of everything from the creation date to the last update date for each item in your database, which allows you to make sure that all files are up-to-date and current with the latest information.
- Better Collaboration
If you share access to your database with other individuals or departments within an organization, you need to be able to share files easily without causing any confusion. This can be accomplished by using shared folders within a network environment.
- Easy access to your data
Using a database management program makes it easy for you to find any information in your database quickly and easily, whether it is by searching through tags or fields in a table, by searching the entire database, or by searching within specific data sets.
- Data quality
Database management software helps you manage your data across multiple sources, including structured and unstructured data as well as external applications such as spreadsheets and files. It also allows you to analyze and correct inconsistent data that’s been entered into your database, which can lead to improved accuracy and consistency overall.
- Efficient use of resources
When using an existing relational database management system (RDBMS), you can easily switch between different databases without having to re-create all your data structures or make significant changes to your application code. This reduces development time and costs by allowing you to focus on creating your business logic rather than dealing with technical details like data replication or indexing algorithms.
The software helps save time and effort in managing databases. It is a great tool to manage the data and make it more effective by providing ease of navigation and access.
Uses of Database Management Systems
