What is a DBMS and what does it do?

A database management system (DBMS) is software that allows you to store, download, add, edit, and delete data files. DBMSs also allow you to manage the database schema, that is, modify the structure of the database.

Data inconsistency issues arise when multiple forms of the same data exist in different locations. It is difficult to determine which data set, if any, is complete and accurate.

How a DBMS works

A database management system consists of a collection of integrated software components that allows its users to interact with one or more databases and provides access to all stored data. In short, a database management system allows you to perform all the necessary database administration operations. The components of each DBMS are software (operating system, application software, etc.), hardware (storage devices), a query processor (user input interpreter), a database access language (required for data manipulation), and data.

typical tasks

A database management system allows users to perform all database administration tasks, such as setting user accounts and permissions, performance monitoring, security, backup, and recovery.

Principal functions

The main functions of the database management system are:

Allow multiple users to access a single database simultaneously. Establish and preserve user access permissions and security guidelines. Frequent data backups and fast data recovery in the event of a breach. Establish database policies and guidelines to safeguard data integrity. Configure dictionary definitions and summaries of the available information.

DBMS types

Centralized System

A centralized database is stored in only one location. The advantage of the centralized system is the low risk of data loss. As such, data manipulation will not influence the basic data. On the other hand, centralized databases are huge, which means response time can be very slow.

distributed system

A distributed database is stored on two or more servers on the same or separate networks. Distributed systems have a big advantage over centralized systems: if one network/server fails, it won’t affect the entire dataset.

Federated system

A database management system is a system that maps multiple databases into a single federated database. A federated database system can be categorized as one of the following:

loosely coupled

To function properly, a loosely coupled federated database requires component databases to build their own federated schema. Typically, a user will access another component database system by using some of the multiple database languages. Doing so will remove all levels of location transparency, forcing the user to have direct knowledge of the federated schema. Users have to import the data they need from another database and integrate it with their own to form a federated schema.

tightly coupled

This type of database system consists of component systems that use separate processes to build and publish an integrated federated schema.

block chain

The database is shared in the form of an encrypted ledger, allowing the information to be open to everyone.

Benefits of using a DBMS

The benefits of DBMS are tangible, especially when dealing with ever-growing and sensitive data such as that found in healthcare organizations.

Have reliable data

With a well-structured database management system and a specific set of data tools, you’ll be able to process and share your data more accurately.

Efficient data integration

With a DBMS, you can easily deploy data from multiple sources to get a more accurate picture of various segments of your business. Also, a lot of manual work could be automated to improve the efficiency of your business.

enhanced security

A DBMS allows its users to share, collect, and store data securely.

Increased productivity and better data interpretation

Manual data cleaning and preparation can be automated. By doing so, you will save a lot of time that can be spent on developing trading strategies.

Challenges of implementing and managing a DBMS

As the number of data types increases, so does the collection effort. Data interpretation options also increase. Many people anticipate that their choice of database management system will not be sufficient for their business needs. The most common challenges of implementing and managing DBMS are:

Increasing data variability

Many companies find it difficult to choose the right option to effectively visualize, that is, to interpret the data obtained in the best possible way to improve their business practices.

scalability limits

Every existing software has resource and scalability limitations. Therefore, it is necessary to predict the resources needed to support your requirements.

Steady increase in data volume

More data collection leads to more profit, but there is a storage problem. You need to ensure that your business never experiences data loss.


Experiencing a data breach leads to huge gains and loss of reputation. There is no such thing as too many layers of security.

How to choose the right DBMS for your company

Understand your existing database(s)

Having a perfectly implemented database management system is a crucial step for the success of your business. Therefore, it is very important to see which data model best suits your business.

Understand your database needs

Every business is different, so it’s essential to select the features your business needs. Otherwise, you may end up paying for features you don’t need and missing essential features you do need.

Define your goals

Depending on your business goals, you need to carefully choose the right DBMS. Today, the choice of DBMS is crucial for business growth. Some of the most important questions to consider are:

Will a relational model suffice for your data structure, or will you have to manipulate unstructured data? Will the system keep your data consistent? Can you keep your data safe, that is, can you back up and restore your data efficiently? Can you modify the DBMS according to your business needs?

DBMS Examples

Oracle – This DBMS can be used to store large amounts of data. Oracles system’s relational database framework allows its users to access all data in less than a second.
MySQL: MySQL is one of the most popular open source relational database management systems. It includes a client-server structure and is characterized by a simple syntax and uncomplicated features.
IBM Db2 DBMS – This highly professional DBMS enables its users to perform real-time analysis and, even for the most intense workloads, maintain low latency transactions.
MongoDB – MongoDB is a highly configurable time series DBMS that allows users to quickly modify data and manage data structuring needs at any time.
PostgreSQL – This open source DBMS supports both relational and non-relational queries in SQL and JSON. PostgreSQL is optimized for all popular operating systems.


A DBMS can greatly improve your data processes and increase the efficiency of your business. Since all the time-consuming and repetitive tasks are automated, using a database management system will save a lot of time. Choose the perfect DBMS for your business and start growing today.
