Imagine the case where the DBAs runs a trace and finds that a specific database query which exists in a stored procedure and manipulates data has slow performance and needs to be rewritten. In this case the DBA will discuss this with the designer (developer) of the stored procedure in order for the latter to perform the required analysis and then redesign/optimize the stored procedure accordingly. The DBA is responsible for the environmental aspects of a DBMS like the databases integrity, sql dba developer performance, backup, security, installation of new DBMS software, etc. You should now be connected to the Oracle database, and you can start creating and executing SQL queries, managing database objects, and using the other features that SQL Developer provides. Like in the first example, a comprehensive performance tuning would require all three DBMS professionals working together in some of its aspects. Also, all three professionals must be capable of “reading” and writing T-SQL queries.

Additionally, all three roles should work together in the case of data archiving and so on. A central subject of DBA philosophy is the balance between ownership and responsibility. If I’m to be held responsible for the non-operation of a database (and I will be) then I should have the implicit right to stop anyone from doing anything that will compromise its operation. However, having a say in related matters is not the same as having complete ownership. A development database is there for developers to use, not to keep me in a job and let me practice my DBA skills.

High-Performance Database Optimization and Security Enhancement

So under this context, the DBA should be capable of writing T-SQL queries with ease, not for manipulating data within the databases (this is the developer’s job) but for performing automated, administrative tasks. An example for performing automated tasks in a DBMS is to design and implement a stored procedure which can be executed on a scheduled-time basis. Can programmers become production DBAs, and can network admins become development DBAs? Programmers don’t usually know the finer points between raid 5 and raid 10, so they have some hurdles before they can design a database server that can scale effectively at the right price point.

  • It provides a wide range of features through an intuitive graphical user interface, making it an essential tool for anyone working with Oracle databases.
  • They are better than experienced people from the same domain.
  • If you would like to learn in a short span of time, this course is a good choice.
  • However, having a say in related matters is not the same as having complete ownership.
  • For example, the area that is probably improved most frequently is the SQL Optimizer, on which any application you develop is going to depend.
  • The real-time scenarios given by trainers helped me understand the concepts better.

Along with this, SQL Administrators are also needed to manage, monitor, and secure database servers. This training course will provide you with a complete set of skills to help you land a high-paying job in any of the best companies around the world. Though, doing only this is not really enough for performing an efficient and comprehensive performance tuning.

Implementing Security

If a system is configured well, then all that should be left to fix are small intermittent problems, with the occasional recovery. Once a system is implemented, things should die down until the next implementation. Apart from when you hit a severe problem, the pace of work is sometimes a little slower, with more planning and care taken over each action. Massive hardware resources and better tools have also made the job easier.
