This article focuses on Database Management Software, including its capabilities, advantages, and challenges. Let’s kickoff by defining what a Database is: it is a collection of electronic data that is processed to create and discover useful information. Thus, Database Management is the practice of collecting, storing and using data to optimize its usefulness and unearth helpful information to enhance decision-making processes and make it easier to base action on specific information.

Before we delve into the intricacies of Database Management Software, let’s define two of its key components: information and data.

What is information and what is data?

When talking about Database Management Systems, it is nearly inevitable to see the concepts of information and data used frequently and sometimes interchangeably. This occurs even though they have key differences that set them apart.

What is data? Data is raw, unstructured collections of facts (qualitative and quantitative) used and processed for reference or analysis. Data is not information - it becomes information when it is processed, interpreted, organized, structured, or presented. In other words, information provides context for data. With this being said, data and information are interwoven with one another in such a way that it is hard to separate the two.

So, what is information? As we stated, information is derived from sets of data that are processed in a meaningful way through context, relevance, and purpose. Information provides meaning and improves the reliability of data.

Here are a few highlights to keep in mind to differentiate information and data:

  • Data is used as input but information is the output of data.
  • Data is unprocessed facts but  information is processed data.
  • Data doesn’t rely on information but information only exists because of data.
  • Data is not specific but information is specific.
  • Data doesn’t possess meaning but information possesses a clear, logical meaning.

Now that we’ve cleared this up, let’s examine what is a Database Management System (DBMS).

What is a Database Management System (DBMS)?

According to the What is DBMS website, the question of what is a Database Management System (DBMS) is answered as a “collection of programs for managing data and simultaneously support different types of users to create, manage, retrieve, update, and store information.” In essence, a DBMS is a software tool that stores, modifies, manipulates, and extracts data from a database. The DBMS solution provides an interface between the user and the database.

A Database Management System receives instructions from Database Administrators (DBAs) who provide commands to load, retrieve, modify, or manipulate existing data. 

A Database Management System is comprised of at least nine key components: hardware, software, data, users, languages, query processors, database engine, database manager, and procedures.

  • The hardware refers to the actual computer system in which the database is accessed. Additionally, it also encompasses secondary storage devices such as hard disks and database machines.
  • The software is the actual DBMS solution that controls and maintains information consistency.
  • Database engine: Core software component that performs functions related to data storage and data retrieval.
  • Data is the single greatest component in this mix. It is the essential element that makes up the entire database.
  • Users access data on demand by leveraging the DBMS interface. The different types of users include end users, application programmers, and database administrators.
  • The different types of DBMS languages include Data Definition Language (DDL), Data Manipulation Language (DML), Database Access Language (DAL), and Data Control Language (DCL).
  • Query processors: This component acts as the intermediary between users and the DBMS data engine to communicate query requests.
  • Database manager: Component that handles the functionality of queries and data at runtime (runtime database manager) and the functionality associated with the data within databases to create, delete, backup, restore, clone, and perform other maintenance tasks.
  • The procedures are the guidelines that govern the design of the database.

According to this definition from IBM, database management includes four types of databases and they are: 

  • Hierarchical: As defined by its name, data is organized hierarchically in a tree-like format. Data is represented via parent-child relationships where the parents can have many children but the children only have one parent.
  • Inverted list or network: In terms of data relationships, this type of DBMS allows each child to have as many parents as necessary. It helps address more complex relationships.
  • Relational: By far the most widely used DBMS solution, this type normalizes data in rows and columns in a table format. Relational databases are stored in fixed structures and are manipulated by using SQL. A significant advantage of relational databases over hierarchical databases is that they are non-navigational, meaning programmers don’t need to be knowledgeable about the structure of the database.
  • Object-oriented: Data is stored in the form of objects. The database is a collection of objects that store data member values and operations.

Capabilities of Database Management

Some of the chief capabilities of Database Management include the following activities:

Access, organize, store, and update data. 
DBMS solutions provide users with the tools to perform all activities related to the overall management of the database itself. From accessing, organizing, storing, and updating...it is all about obtaining value from data to turn it into insightful information that aids in numerous decision-making processes within the business ecosystem.

Database Management systems provide the interphase to manipulate data in databases or to manage the database structure itself. Through its systematic approach to managing databases, DBMS solutions facilitate administrative actions such as change management, disaster recovery, compliance, performance monitoring, and more.

Secure data and ensure data privacy.
A key subject that is increasingly becoming an integral part of any company’s information strategy is security. Through the use of several security controls and a variety of tools, databases are secured against threats of loss of privacy or leaks. Database security includes protecting data, applications that process and store data, physical servers, and the network connection that enables users to access the database.

Protecting databases is vital as new and more sophisticated methods of attack are used on a daily basis by hackers and other individuals with malicious intent. Database security takes many forms, such as restricting user access based on the level of use, adding firewalls, encrypting, and even physically protecting database servers by isolating them from potential vulnerabilities.

Data disaster recovery.
As companies become more data-dependent, it is apparent that recovering data in case of loss is vital to restructure a database to its latest state. If a data disaster occurs, companies may lose customer records, transactions, financial information, and other sensitive information that could mean major losses. 

Data loss can take the form of logical errors (software bugs, virus attacks, corruption), physical damage at the server of disk level, and natural disasters that affect data centers. Database disaster recovery involves backup and disaster tolerance. A backup is the copy of important data within a database. Data tolerance is the deployment of IT systems with the same functions in two separate places so if one system fails, the entire system is switched over to its brother system to avoid service interruptions.  With the enforcement of recovery preventive measures, databases are protected against data loss.

Database Management Software advantages

Among the most significant advantages of Database Software, we can find the following:

Database Visualization

Through database visualization tools, database admins can fully understand the raw data that lives in databases and gain value from it by identifying patterns or trends. With database visualization, organizations obtain visual representation and graphics of data that help them understand it and make better, more informed business decisions. By visualizing a database, users get to explore data in a more effective manner that allows for deeper analysis.

Performance Testing

Databases typically include complex sets of data that can create performance issues if not thoroughly examined. With database performance testing, users can take preemptive actions that can help correct any issue that is identified during the testing process. By simulating real-life load for databases, administrators can pinpoint how the database will react under the specific circumstances when multiple users use the database simultaneously.

Database Backup

Database backup and recovery are strategies and procedures that help ensure the database is protected against data loss and the associated problems of reconstruction. By backing up a database, users create a duplicate database for use in case of a crash, data corruption, or any type of data loss. In essence, database backups help recover data easily and reconstruct it in case of loss.

Database Migration

It is the movement of data from one platform to another. Through several stages and iterations, database migration takes into consideration the current state of the database as well as the future needs of the organization, migrating the schema and moving the data simultaneously. One of the main benefits associated with database migration is cost as it enables companies to move from an on-premise database to a cloud database in a cost-effective manner.

Data Redundancy

It is the duplication of data in different places, whether by accident or done deliberately for backup and recovery purposes. DBMS software provides control over data redundancy and saves storage space by doing so. Typically, DBMS solutions use data normalization techniques to avoid unnecessary redundancy and duplicate data.
