What are the major risks of implementing an RDBMS in an enterprise? Are these risks present across all vendors or are the risks vendor-specific?


Sid Adelman's Answer: The risks listed below are very much vendor-specific.

Risk 1 - The demise of your chosen RDBMS. If your RDBMS is acquired by another company, you will probably eventually have to convert - a painful and expensive process that brings little value to your organization.

Risk 2 - The inability of the RDBMS to perform and support your service level agreements. This includes response time, inability to support a given number of concurrent users, inability to meet performance windows, inability to support a high availability system, and inability to expand.

Risk 3 - This involves the RDBMS support of critical application packages and ERPs. If your ERP vendor does not consider a particular RDBMS to be important, they will not test as well and will not consider that RDBMS in functional and performance improvements.

Risk 4 - Vendor support. Some RDBMS vendors have an excellent reputation for customer support - others do not.
