Computers & IT (Non-Engg)

A database management system is a computer software application that interacts with the user, other applications, and the database itself to capture and analyse data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. DBMS can be used to manage transactional databases, such as HR systems, banking systems and so on. Database administrators (DBAs) use specialised software to store and organise data. The role may include capacity planning, installation, configuration, database design, migration, performance monitoring, security, troubleshooting, as well as backup and data recovery. You can do Oracle DBA course and certification after 12th but the chances of getting a job in medium or large size jobs are very poor unless you complete minimum graduation degree such as BBA. It is my sincere advise to you to pursue graduation degree first, else you will face challenges and disappointments while searching for a job.

B.Sc Computer Science is 3 years of Graduation course while B.Tech is 4 years of Graduation course after which you will get Engineer's Degree.
B.Tech is definitely better! CSE is the most popular engineering stream and there are colleges where special emphasis is given on this stream like UTM Shillong is offering this specialization in association with IBM. This university offers:
B.Tech Computer Science and Engineering with specialization in Cloud Computing & Virtualization Technology in academic collaboration with IBM
B. Tech (Computer Science and Engineering with specialization in Oil & Gas Informatics)
These are great specializations and have good career prospects.
