Progress
DataServer
for ORACLE Guide


Programming Considerations

The Progress ADE used in conjunction with the DataServer allows you to develop applications that transparently access data from multiple sources. The DataServer for ORACLE achieves database transparency for applications running against Progress and ORACLE, but some of the ways it accomplishes this might affect how you develop applications. This chapter discusses the differences between Progress and ORACLE that you have to consider when you plan your applications and design your databases. In addition, your applications might have to accommodate the strategies that the DataServer uses to resolve these differences.

This chapter discusses equivalencies and differences between ORACLE and Progress in the following areas:

Mapping Progress to ORACLE

The material in this chapter is also of interest to users who plan to migrate a Progress database to ORACLE. However, this migration raises several additional issues that are discussed in the "The Progress-to-ORACLE Utility" section in The DataServer Tutorial."
