  • Purpose Identify Informix connectivity products and explain how to configure the related components for Microsoft Windows clients to enable client applications to access Informix databases through ODBC
  • Slide 4
  • Tuesday, May 24, 2005 Outline Overview of the latest IBM Informix Client SDK List available Operating System platforms Describe Client configuration Identify Informix client connectivity components Describe and Demonstrate configuration/testing Identify potential problems List Documentation
  • Slide 5
  • Tuesday, May 24, 2005 Client SDK 2.9 Overview Informix Client SDK V2.9 contains a collection of APIs that can speed development of applications that work with Informix database servers. Using Client SDK, developers can: Write applications in a number of languages including Java, C++, C, and ESQL Write applications using tools that work with ODBC and/or OLE/DB. This flexibility allows more choice in programming environments, promotes easier and faster application development, and can reduce the cost of training developers in new skills Build one application to access multiple Informix databases. This can save maintenance and support expenses, minimize downtime, and speed application development
