Powerbuilder for the front end and Oracle 7.3 for the back end. Powerbuilder comes the closest to Clipper as far as flexibility and features. We used a number of 3rd party libraries with Clipper. You will find similar support for Powerbuilder. Oracle 7.3 is the most current version of Oracle. It has a number of enhancements such as Bitmapped indexes that provide some of the same benefits as the Comix/Successware drivers for Clipper. In general, you want to stay pretty close to the current releases with Oracle. (We prefer to let the market test them before jumping to a new release.) Oracle8 is due out this summer and it promises to add some very desireable features as well... You will need to find a home for your database, and that depends largely on your transaction volume, concurrent users, etc. A logical step might be Windows NT, but you will need to work through the issues listed above first to determine whether NT is the right place. Don't look at Netware NLM for Oracle...
