The volume of data shared across enterprises is increasing rapidly, making it difficult to manage their data. One possible solution for data management is Database Management Software (DMS) that allows organizations to improve data accessibility and simplifies the process of documents management.

In this blog, we’ll delve into how DBMS works and shed some light on the benefits it brings to the table. Let’s get right into it!

What is Database Management Software (DBMS) used for?

A Database Management Software or DBMS is used for storing, manipulating, and managing data in a database environment. It enables users to design a personalized database to meet their analytics and reporting needs. Database design also supports creating, implementing, and maintaining an organization-wide data management system.

Generally, Most DBMS packages allow users to perform operations like database creation, storing data, updating data through SQL queries.

Over the years, new database management software has been introduced with different architecture and application focus to meet the modern-day requirements., providing support for data modeling, data integration, multimedia data, etc.

An example of a typical database would be MySQL, a managed database service to deploy cloud-native database applications. Some other options include Microsoft SQL Server, SAP HANA, Oracle, and Microsoft Access.

Main Features of a DBMS

Main Features of a DBMS

An efficient database management software should include the following features:

  • Data Normalization

The risk of data duplication in a database is relatively high as multiple users share it simultaneously. Data normalization mitigates this risk and minimizes the chance of destructive anomalies appearing. No data redundancy and repetition save storage and significantly improve access time.

  • User-defined rules and constraints

Integrity constraints help organizations prevent accidental damage to the database by authorized users. A DBMS allows users to define validation and integrity rules and conditions to ensure data satisfies the semantics.

  • Security protocols

Security controls protect the integrity of a database as well as the data and records residing in it. Some essential DBMS security controls include data encryption, user authentication, and user authorization.

  • Data backup

A backup protects your database against data loss. A copy of files stored in a database must be available to reconstruct data in case data get lost or corrupted. Most DBMS support logical and physical data backup.

  • Data structuring

A DBMS must allow users to organize information in a database in a clear hierarchical structure. It means all objects, records, and tables can be arranged systematically, like a catalog, so the records can easily be accessed and retrieved.

In addition, you must also look for various features and functionality depending on your use case. For example, a DBMS should offer easy database customization options, support multi-user access, and contain a metadata library.

Types of Database Management Systems

These can be broadly classified into four types. The most popular types of database management systems with examples include:

1- Hierarchical

A hierarchical DBMS stores data in a parent-children relationship node — each of which represents a particular entity. This type of DBMS allows one-to-one and one-to-many relationships, i.e., a parent node can have one or multiple child nodes, whereas the children node can only have one parent node.

2- Network

A network DBMS is a model that supports many-to-many relationships, which helps store real-life relationships between entities. It is an extension of the hierarchical DBMS that allows modelers to design a more flexible model. In this type of DBMS model, the child nodes are represented by arrows.

3- Relational

A relational DBMS is a model where relationships are based on the data of the entities. Compared to hierarchical and network models, it offers greater flexibility and allows for more simplified relationships between entities, making it a popular choice among data modelers. Data stored in fixed structures can be organized efficiently using SQL.

4- Object-Oriented

An Object-Oriented DBMS — as the name suggests — is based on object-oriented programming (OOP). It’s a type of DBMS where entities are represented in objects and stored in memory.

It provides a unified programming environment and is compatible with various programming languages, including Java, C++, .Net, and Visual Basic, to name a few.

Advantages of a Database Management Software

Now that we have familiarized ourselves with the definition of database management and the types of DBM software, let’s move ahead and look at the functions and benefits of database management system:

  • Better Data Sharing

Implementing a DBMS allows onsite and remote users to quickly share the data by following the correct authorization protocols. It helps improve data accessibility, enabling users to share the organizational data swiftly and efficiently.

The improved data processes provide a smart solution to database queries, even the ad-hoc and impromptu ones. It results in accurate and swift data access, ultimately facilitating more informed and timely decision-making.

  • Better Security

Data security is a vital aspect of a database. A DBMS only allows authorized users to access the database. The authentication is managed using a username and password. Controlled user access prevents unauthorized users from accessing resources in a database, which can potentially violate the integrity constraints.

  • Effective Data Integration

A DBMS provides an integrated picture — a bird’s eye view, so to speak — of the operations and processes of an organization. The unified data allow companies to evaluate the controls and performance effectively and timely.

  • Informed Decision-Making

Data-driven decision-making can give businesses a competitive advantage, but data is valuable for decision-making only when it is reliable. Using a DBMS, organizations can ensure data accuracy and quality trusted for analysis and decision-making.

  • Increase In Efficiency and Productivity

Deploying a DBMS help increase data accessibility and streamline information. It boosts the end-user productivity and leads to improved efficiency and speed for an organization.

  • Data Integration

Instead of storing data in isolated database systems, a single interface can manage databases with physical and logical relationships.

Applications of Database Management Software

Following are some of the applications of DBMS in different industries:

  • Banks: In the banking sector, DBMS is used to store client info, account activities, disbursements, credits, and mortgages
  • Airlines: Flight bookings and scheduling info is stored in databases.
  • Education: Student information, course registrations, and results are accumulated in database systems.
  • Telecommunication: Databases store call archives, monthly bills, retaining balances, and other call-related information.
  • Economics and Finance: DBMS stores data about bonds, transactions, and acquisitions of fiscal instruments, such as shares and stocks.
  • Sales and Marketing: Prospect and customer information is stored and accessed via databases.
  • Human Resources: Records about workers, remunerations, payroll, deduction, generating salaries, and more information are kept in database systems.

A DBMS is a collection of programs that allows data to be stored, reformed, and extracted from a database. There are several kinds of database management systems (four of the most popular ones are discussed in this blog). The terms hierarchical, relational, object-oriented, and network denote how a database management software organizes data internally.

It can be challenging for data-driven enterprises to operate DBMS as it requires in-house expertise. Moreover, the cost, size, and performance of a DBMS varies with the organization’s requirements and use cases and should be evaluated accordingly.
