The EDC tutorials, Modeling Progress Corticon Rules to Access a Database using EDC and Connecting a Progress Corticon Decision Service to a Database using EDC, provide a walk through setting up Microsoft SQL Server 2014 to create tables that Corticon Studio and Corticon Server then use to create, read, update, and delete data. We recommend completing or reviewing both tutorials before reading this chapter. This chapter extends the information covered by that guide.“Writing Rules to access external data” chapter in the Rule Modeling Guide extends the tutorial into scope, validation, collections, and filters.“Relational database concepts in the Enterprise Data Connector (EDC)” in this guide discusses identity strategies, key assignments, catalogs and schemas, database views, table names and dependencies, inferred values, and join expressions.This chapter, “Implementing EDC” discusses the full set of options and parameters when using EDC, and then takes a close look at mappings and validations in a Corticon connection to an RDBMS.Topics in Packaging and deploying Decision Services in this guide describe the parameters for deploying Decision Services that use EDC.“Vocabularies: Populating a New Vocabulary: Adding nodes to the Vocabulary tree view” in the Quick Reference Guide extends its subtopics to detail the available fields for Entities, Attributes, and Associations.
