Learn all about database management software, its features. functions, and application. The blog answers common questions about what is database software and what are the prominent types of data management. Additionally, it also delves into the role of DBMS in business, along with the definition of DBMS, types, benefits, use cases, and examples of database management software in detail.

DBMS Definition: What is Database Management Software (DBMS)?

A Database Management Software or DBMS software is used for storing, manipulating, and managing data, such as format, names of fields, and record and file structures in a database environment. Users can construct their own databases using a DBMS to satisfy their business requirements. For example, dBase was one of the first DBMS for micro-computers. Database design also supports the creation, design, implementation, and maintenance of an organization-wide data management system.

To interact with a database, a DBMS package generally uses SQL queries. It receives a command from a database administrator (DBA) and prompts the system to perform the necessary action. These instructions can be about loading, retrieving, or modifying existing data in the system.

Database System Environment and Data Security

Over the years, new DBMS software has been introduced with different architecture and application focus. One such example of database software is advanced database systems that meet the requirements of modern-day database applications in terms of offering data modeling, data integration capabilities, support for multimedia data, etc.

What Type of Information is Stored in a Database?

The purpose of a database is to store different data in several ways. Some of the types of data that can be stored in a database are:

  • Textual data
  • Numerical data
  • Binary data
  • Data and time

Most Popular Database Management Software (DBMS)

A database management software features data independence, as the storage mechanism and formats can be changed without altering the entire application within the database. Common DBMS software such as MySQL, Microsoft SQL Server, Microsoft Access DBMS, Oracle, IBM DB2, and FoxPro are a few data management software examples used widely. A common DBMS tool, MySQL, a free business database software, is a high-performing database software that helps enterprise users build scalable database applications. Similarly, the features of FoxPro include creating, adding, editing, and removing information from a database.

Main Features of a DBMS

In order to achieve the benefits of a data management system, the database management software should have the following features:

·       Low Repetition and Redundancy

In a database, the chances of data duplication are quite high as several users use one database. A DBMS reduces data repetition and redundancy by creating a single data repository that can be accessed by multiple users, even allowing easy data mapping while performing ETL.

·       Easy Maintenance of Large Databases

Most organizational data is stored in large databases. A DBMS helps maintain these databases by enforcing user-defined validation and integrity constraints, such as user-based access.

·       Enhanced Security

When handling large amounts of data, security becomes the top-most concern for all businesses. A database management software doesn’t allow full access to anyone except the database administrator or the departmental head. Only they can modify the database and control user access, making the database more secure. All other users are restricted, depending on their access level.

·       Improved File Consistency

By implementing a database management system, organizations can create a standardized way to use files and ensure consistency of data with other systems and applications. Manipulating and streamlining advanced data management systems is essential. The application of an advanced database system allows using the same rules to all the data throughout the organization.

·       Multi-User Environment Support

A database management software features and supports a multi-user environment, allowing several users to access and work on data concurrently. Db software also supports several views of the data. A view is a subsection of a database that’s distinct and dedicated to specific operators of the system.

As a database is typically accessed by multiple operators simultaneously, these operators may need different database views. For example, operator A may want to print a bank statement, whereas Operator B would want to only check the bank balance. Although both are querying the same database, they will be presented with different views.

In addition to the above-mentioned features, it is also important to look for qualities of a good database system, such as it should represent logical structures of the problem, eliminate redundant data storage, and offer good data access.

DBMS Language

To communicate database updates and queries, DBMS language is used. Different types of database languages are explained below:

  1.  Data Definition Language (DDL): It is used to save information regarding tables schemas, indexes, columns, constraints, etc.
  2. Data Manipulation Language (DML): It is used for accessing and manipulating databases.
  3. Data Control Language (DCL): It is used to access the saved data. It also allows to give or revoke access from a user.
  4. Transaction Control Language (TCL): It is used to run or process the modifications made by the DML.

Types of Database Management Systems

There are different database management systems, which can be broadly classified into four types. The most popular type of DBMS software include:

1- Hierarchical

A hierarchical DBMS organizes data in a tree-like arrangement, in the form of a hierarchy, either in a top-down or bottom-up design. The hierarchy is defined by a parent-child relationship, where a parent may have numerous children, but children can only have a single parent.

This type of DBMS commonly includes one-to-one and one-to-many relationships. A one-to-one relationship exists when a parent has a single child. Whereas, in a one-to-many relationship, a parent has multiple children.

As data is hierarchical, it becomes a complicated network, if one-to-many relationships are disrupted.

2- Network

A network DBMS is a slightly complex extension of hierarchical DBMS in which data has many-to-many relationships that appear in the form of a network. The advantages of the network database model are that records are arranged in a graph that can be accessed via numerous data paths. In this database structure, a child can have multiple parents. Therefore, it allows you to model more intricate relationships. The ability to build more relationships among different data types makes these databases more efficient.

3- Relational

A relational model is one of the most extensively used arrangements for organizing databases. It normalizes data and organizes it as logically independent tables. You can perform operations like “Select” and “Join” on these tables. The data is stored in fixed structures and manipulated using SQL.

Shared data depicts relationships between different tables. As data in a table can reference similar data in another table, it preserves the reliability of the connections between them. This is called referential integrity, which is a critical concept in this database model.

4- Object-Oriented

The object-oriented model describes a database as a group of objects, which stores both values and operations/methods. Objects with similar values and operations are grouped as classes.

As this type of database integrates with object-oriented programming languages and utilizes an identical representation model, programmers can leverage the uniformity of a single programming environment. Object-oriented databases are compatible with various programming languages, such as Delphi, JavaScript, Python, Java, C++, Perl, Scala, and Visual Basic .NET.

What is the Purpose of a Database: Advantages of a Database Management Software

Let’s understand what the uses of database software are along with the benefits of database management system with examples and applications:

  • Simplified Data Sharing

One of the main advantages of DBMS is that it allows users (onsite as well as remote) to easily share the data by following the correct authorization protocols. It provides operators access to well-managed data. As a result, they can rapidly respond to variations in the environment.

By using database management software, you can yield speedy responses to impromptu queries as the data is properly managed and up-to-date. In case of any ad hoc query, the database management software returns a response (known as the query result set) to the application.

  • Enhanced Data Safety

The threats of data security breaches become more pronounced when several users access the database. A database management software offers better implementation of data confidentiality and safety guidelines through controlled user access.

  • Improved Data Integration

A DBMS stimulates an integrated view of the company’s data. The company can quickly see how activities in one division of the organization influence other divisions.

  • Better Decision-Making

One of the uses of database management software is to provide access to well-managed data, making it possible for users to make accurate and timely decisions. It offers a streamlined framework to enable data quality initiatives, improving data management procedures and yielding better-quality information.

  • Improved Efficiency

Streamlined data access software, along with the tools that convert data into valuable information, enable operators to make swift, knowledgeable decisions. This improves a database’s performance and efficiency.

Applications of Database Management Software

What is the function of a database management system? Following are some of the applications of DBMS based in different verticals:

  • Banks: Storing client info, account activities, disbursements, credits, and mortgages
  • Airlines: Flight bookings and scheduling info
  • Academies: Learner info, course registrations, grading, and result
  • Telecommunication: Keeping call archives, monthly bills, and retaining balances.
  • Economics and Finance: Storing data about bonds, transactions, and acquisitions of fiscal instruments, such as shares and stocks
  • Sales and Marketing: Storing data about consumers, merchandises, and sales
  • Engineering and Manufacturing: Managing supply chain, and pursuing manufacturing of items and inventory statuses in storerooms
  • Human Resources: Keeping records about workers, remunerations, payroll, deduction, generating salaries, and more

All of these applications of database management software are also often called database management software examples and they serve the same purpose i.e. to help beginners understand the importance of DBMS and their use cases.

Who Uses DBMS: Types of Database Users

There are different database users:

  • Database Administrator: Their main task is to manage the entire database management system. Some people even hire a database management company to take over this task. 
  • Application Programmers: They write programs in different programming languages in order to interact with the database.
  • End-Users: They are the individuals who interact with the DBMS and perform different tasks on databases, such as updating, deleting, retrieving, etc.

These database software users work with DBMS examples such as MySQL, Oracle & IBM, on a regular basis, to attain the benefits of a data management system.

What is Database Control?

Database control is the job of enforcing certain regulations to ensure that correct data is sent to authentic users. The three main aspects of database control are authentication, access rights, and integrity constraints.  Therefore, all data must be aligned with integrity regulation and guarded against unauthorized users. Database control is one of the main tasks of a DBA or database administrator.

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