B.Tech

I will suggest you to go for another degree. At least complete your B.E. /B.Tech degree. Many AICTE (All India Council for Technical Education) approved private/government. Engineering colleges do have lateral entry scheme for Diploma holders. The REASON why I'm asking you to get a B.E. /B.Tech degree is that, now a days there are so many B.E. /B.Tech degree holders. Each year approximately 1.5 Million engineers are graduating from different colleges throughout India. So the competition in market is way too high, now a days. Just with a Diploma it is hard to live a first class life. Even after completing graduation in Engineering many people struggle not to live a 2nd class life during their early years of life. Eventually many go for higher education (M.Tech/MBA) in search of getting decent job. This may sound harsh, but the real corporate world doesn't go easy on us. So go for at least another degree in Mechanical Engineering.

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. (b)Database administrators (DBAs) use specialised software to store and organize data. The role may include capacity planning, installation, configuration, database design, migration, performance monitoring, security, troubleshooting, as well as backup and data recovery. Even if you do DBA certification from Oracle, Microsoft or Informix or IBM DB2, etc. After B.Tech, it may be difficult to get freshers job as most of the large enterprises M.A. Not allow freshers to touch their business critical databases. It is suggested that B.Tech graduates should do few years of programming before seeking DBA certifications for long term career growth and acceptance.
