  3. Advantages • Concurrent users • High Processing Speed • Storage • TSO • Multiprogramming • Multiprocessing • Security • Reliable • Batch Processing

  4. Domains • Banking • Finance • Insurance • Market Research (Retail) • Telecom

  5. So far • Mainframes is a very stable environment • It has been there in the Software Industry for more than 40 years • No new technology can totally replace Mainframes because of its architecture and efficiency

  6. Current trend • Around 80% of Mainframes projects are maintenance projects • Only 20% or less are development projects • The reason being the cost factor. The hardware maintenance cost and the initial investment required is too high.

  7. Current trend • Migration projects are the current trend in the market • Reasons: User friendly screens Maintenance cost

  8. Future • A survey to determine the current demand for mainframes found that more than half of the respondents still have major applications running on mainframes

  9. In DBA • We are working on mainframes right from the day company started. We are experts in PL/I, IMS but we have also worked on COBOL, DB2 Projects. Our clients: ACNielsen, Blue Cross Blue Shield
