To manage large volumes of data, an organization needs the expertise of a database manager. Database managers oversee an organization’s database’s storage, organization, and security. In this article, we will go over the responsibilities of a database manager, their required skills, how to become one, and the salary range. Also, we will discuss database management software, and system a database manager uses and the overall data management system.
Database Manager
A database manager or administrator is responsible for managing, maintaining, and securing an organization’s databases. They ensure that data is correctly stored and retrieved and that databases operate functionally and efficiently. A data manager is an integral part of organizations that rely on databases to store and manage large amounts of information.
Responsibilities of a Database Manager
Database managers have multiple responsibilities within an organization. However, this responsibility is usually based on the size and needs of the organization, but generally, it can include:

After getting hired as a database manager, you’ll typically undergo on-the-job training for an average of 3-6 months. This training period allows you to learn the specific skills and techniques required for your job and employer. It’s an opportunity to gain competency as a database manager.
Database Manager System
A database management system (DBMS) is a software system a database manager uses to manage and organize data in a structured manner. It provides an interface for users to create, modify, and query databases and manage the security and access controls for those databases. DBMSs are essential for efficient and reliable data management, ensuring data integrity, providing data security, and facilitating data sharing among different departments, teams, and applications.
DBMS optimizes data organization by following a database schema design technique called normalization, which splits a large table into smaller tables when any of its attributes have redundancy in values.
There are various types of database management systems available, such as cloud database management systems, columnar database management systems, distributed database management systems, graph database management systems, hierarchical database management systems, HTAP database management systems, in-memory database management systems, object-oriented database management systems, NewSQL database management systems, and time-series database management systems.
Benefits of Using a Database Manager System
- It offers concurrency control
- Good security features
- Audit trails
- Data lifecycle management.
Database Manager Software
A Database Management System (DBMS) is a software tool that a database manager uses to enable users to manage databases easily and efficiently. It provides an interface between the data and the software application, allowing users to create, protect, read, update, and delete data in a database.
What you should consider when choosing database management software:
- Compatibility: Ensure that the database management software is compatible with the database systems you are using (e.g., MySQL, Oracle, SQL Server, etc.).
- Scalability: Choose software that can handle your database needs and scale up as your business grows.
- Security: The software should provide robust security features to protect the integrity of your data and control access.
- Automation: Look for a tool that automates repetitive tasks, saving time and resources.
- Collaboration: The software should facilitate collaboration among team members and provide a system for effective communication.
- Data replication: The tool should support data replication to ensure data availability in the event of data loss from one source.
- Customization and reporting: The software should offer customizable reports and analytics to help you make informed decisions.
- Support and documentation: Opt for a tool that provides comprehensive documentation and responsive customer support.

What Is the Difference Between a Data Manager and a Database Manager?
A data manager and a database manager are necessary for a successful organization. While one person can possess both skill sets, it is more common to have separate individuals for each role due to the unique skills and expertise required for each. This is where their main difference lies: in their roles and responsibilities.
The role of a data manager involves using data to achieve the organization’s goals, while database managers are responsible for maintaining and managing the database system that stores the data.
A data manager understands the organization’s goals, mission, and business. They know what the company provides to customers and clients and how those services or products are utilized. They also know how the organization’s data can improve various aspects, such as identifying new opportunities, enhancing communications, and boosting marketing. On the other hand, a database manager knows the technical aspects of the database software, system, or platform. They understand how technology affects data storage and access and are familiar with industry best practices for database and information management. They also know how to integrate different data storage solutions and ensure access to data for relevant employees or management members throughout the organization.
What Are the Duties of a Database Manager?
The common duties of database managers involve the following:
- Ensuring data is collected and managed in the database
- Understanding the organization’s business
- Software installation and maintenance
- Supervising and training staff.
- Data analysis and reporting.
- Ensuring database security
What Are the Four Types of Database Management?
There are four main types of database management systems, which can be categorized as follows:
#1. Relational Database Management Systems (RDBMS)
These databases are based on the relational model, which organizes data into tables with rows and columns. RDBMSs use Structured Query Language (SQL) for data manipulation. They are widely used in the industry due to their flexibility, scalability, and support for ACID (Atomicity, Consistency, Isolation, and Durability) properties. Some popular RDBMSs include MySQL, PostgreSQL, Oracle, and Microsoft SQL Server.
#2. NoSQL Database Management Systems
These databases provide a more flexible schema than RDBMSs, and the design enables the handling of unstructured data, large-scale data, and real-time processing. NoSQL databases can be further classified into four subcategories: key-value, document, column store, and graph databases. NoSQL databases often sacrifice ACID properties for better performance and scalability.
#3. Network Database Management Systems
These databases use a data model similar to hierarchical ones but allow multiple parent-child relationships in the tree structure. Network databases were popular during the 1960s and 1970s but have been mostly replaced by RDBMSs in modern computing due to their complexity and difficulties in searching for data.
#4. Object-Oriented Database Management Systems (OODBMS)
These databases store data as objects and their attributes, closely integrating with object-oriented programming languages. OODBMSs allow data and programs to function as a single unit, making working with diverse data structures and extensible models easier. However, OODBMS are still relatively new and have limited commercial adoption.
Apart from these main types, in-memory database management systems store data in memory instead of disk-based storage, significantly improving performance by reducing I/O latency.
What Is the Most Used Database Manager?
The following database management software is commonly used:
- Oracle RDBMS: Oracle database is the most widely used object-relational database management software. It has strong security and support for large databases and reduces the CPU time to process data.
- SQL Developer: SQL Developer is an open-source DBMS tool that developers favor for its efficiency in designing, developing, and performing other database management activities.
- MySQL: MySQL is one of the most useful database management tools that top companies like Google, LinkedIn, YouTube, PayPal, and Twitter use.
- ManageEngine Applications Manager: ManageEngine Applications Manager is a widely used performance-oriented database management solution. It provides deep insight into business-critical applications and supports over 20 databases.
