Database Administrator Education

A bachelor's degree in computer science is a prerequisite for many IT jobs. However, demand is so great for DBAs that some entry-level data jobs require only a two-year or associate's degree in computer science or information systems.

We are happy and proud to say that we have strong relationship with over 700+ small, mid-sized and MNCs. Many of these companies have openings for DBA analyst. Moreover, we have a very active placement cell that provides 100% placement assistance to our students. The cell also contributes by training students in mock interviews and discussions even after the course completion.

• Data modeling and database design. The DBA must possess the ability to create an efficient physical database design from a logical data model and application specifications. If the data resource management discipline has not been created, the DBA also must be responsible for data modeling, normalization, and conceptual and logical design.
• Metadata management and repository usage. The DBA, or sometimes the Data Architect (DA), must collect, store, manage, and enable the ability to query the organization's metadata. Without metadata, the data stored in databases lacks true meaning.
• Database schema creation and management. A DBA must be able to translate a data model or logical database design into an actual physical database implementation and to manage that database once it has been implemented.
• Backup and recovery. Implementing robust backup and recovery procedures is the insurance policy of the DBA. The DBA must implement an appropriate database backup and recovery strategy based on data volatility and application availability requirements.
• Ensuring data integrity. DBAs must be able to design databases so that only accurate and appropriate data is entered and maintained. To do so, the DBA can deploy multiple types of database integrity including entity integrity, referential integrity, check constraints, and database triggers. Furthermore, the DBA must ensure the structural integrity of the database.
• Performance management and tuning. Dealing with performance problems is usually the biggest post-implementation nightmare faced by DBAs. As such, the DBA must be able to proactively monitor the database environment and to make changes to data structures, SQL, application logic or the DBMS subsystem to optimize performance.
• Ensuring availability. Applications and data increasingly are required to be up and available 24x7. The DBA must be able to ensure data availability using non-disruptive administration tactics.
• SQL code reviews and walk-thrus. Although application programmers usually write SQL, DBAs usually are blamed for poor performance. Therefore, DBAs must possess in-depth SQL knowledge so they can understand and review SQL and host language programs and to recommend changes for optimization.
• Procedural skills. Modern databases manage more than merely data. The DBA must possess procedural skills to help design, debug, implement, and maintain stored procedures, triggers, and user-defined functions that are stored in the DBMS.
• Data security. The DBA is charged with the responsibility to ensure that only authorized users have access to data. This requires the implementation of a rigorous security infrastructure for production and test databases. And a database auditing capability to document compliance.
• Capacity planning. As data consumption and usage continue to grow, the DBA must be prepared to support more data, more users, and more connections. The ability to predict growth based on application and data usage patterns and to implement the necessary database changes to accommodate the growth is a core capability of the DBA.
• General database management. The DBA is the central source of database knowledge in the organization. As such he must understand the basic tenets of relational database technology and be able to accurately communicate them to others.
• General systems management and networking skills. Because once databases are implemented they are accessed throughout the organization and interact with other technologies, the DBA must be a jack of all trades. Doing so requires the ability to integrate database administration requirements and tasks with general systems management requirements and tasks (like job scheduling, network management, transaction processing, and so on).
• ERP and business knowledge. For businesses doing enterprise resource planning (ERP) the DBA must understand the requirements of the application users and be able to administer their databases to avoid interruption of business. Most ERP applications (SAP, PeopleSoft, etc.) use databases differently than homegrown applications. DBAs require an understanding of how the ERP packaged applications impact the business and how the databases used by those packages differ from traditional relational databases.
• Extensible data type administration. The functionality of modern DBMSs can be extended using user-defined data types. The DBA must understand how these extended data types are implemented by the DBMS vendor and be able to implement and administer any extended data types implemented in their databases.
• Web-specific technology expertise. For e-businesses, DBAs are required to have knowledge of Internet and Web technologies to enable databases to participate in Web-based applications. Examples of this type of technology include XML, CGI, DBA, Ruby on Rails, TCP/IP, Web servers, firewalls, SSL, and so on.
• Storage management techniques. The data stored in every database resides on disk somewhere (unless it is stored on one of the new main memory DBMS products). DBAs must understand the storage hardware and software, including how it interacts with the DBMS.

The dba must be highly responsible.

The dba must always be ready with A backup.

He must be lazy, so that he can perform lot of automation to reduce the monotonous work.

Must be a fast learner and should update themselves with latest technology updates.

A colleague of mine, who is a DBA, recommends you start by learning the SQL programming language. SQL is the programming language that database queries are written in.

Our courseware is designed to give a hands-on approach to the students in DBA. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students’ time and commitment.

The Microsoft Certified Database Administrator (MCDBA) certification provides proof of your ability to design, implement, and manage SQL Server 2000 databases.

Some firms employ a single DBA and multiple developers, others multiple DBAs but no developers. As a general rule, I would say that there is a larger market for Oracle developers than for Oracle DBAs.My own position is that of a DBA/Developer because my job responsibilities cover some of both tasks.

DBA tends to mean different things at different companies. Some companies have DBA design schema, write procedures, and other wise work with the development teams. Other companies put more focus on the infrastructure side, resolving I/O issues, HA/DR, etc. I don’t think either role is “dying” but I do think they are evolving.

Some people say just drop it in the cloud and you don’t need a DBA. I disagree, Cloud has brought with it challenges. It often promises HA, but there is certain knowledge required for true HA. Azure, AWS, etc have all had, rare, but major outages that have effected tens of thousands of customers. Many of those customers were down as a result. Outages happen, but you have less control in the cloud. So ideally you want someone who understands how your cloud platform works and who can help you take steps to mitigate issues.

Database folks also already tend to move or spend part of their time in non traditional DBA stuff. Its real easily to move from dba to db developer. Its a bit harder to move into BI but doable. Its actually a very flexible role in regards to its ability to allow one to move into other areas.
