Course Outline

Module 1: JavaScript:  Add an incredible amount of functionality that was not formerly available: 

  • String functions: substring, string length, string replace, toUpper, toLower, charAt, etc.
  • Math functions: round, floor, ceiling, truncate, random numbers, etc.)
  • Date functions: date or time arithmetic, validate dates, create formatted date/time variables

Module 2: REST Web Service calls and XML: Learn to work with RESTful web services

  • Testing RESTful web service interface in a Web Browser using Rest Client Extension
  • Learn XPath syntax to parse XML response and using free online tools
  • How to use the Studio REST Client Element  and to parse XML responses in Studio    
  • Fetchtimeout and Fetchaudio review    

Module 3: REST Web Service calls and JSON: 

  • Learn JSON syntax, how to parse JSON responses, and test using free online tools    
  • Use the Studio Rest Client element and  JavaScript in Studio to parse JSON results    

Module 4: SOAP Web Services: Understand how to invoke a SOAP and WSDL based web services

Module 5: Database: Use the SQL Database element in Studio

  • Select data and execute stored procedures on a SQL-based database
  • Select multiple rows into XML and parse the result     
  • Event Handling to catch exceptions and switch to backup database

Module 6: Modularization and Multiple applications

  • SubFlows – Subroutines (or ‘functions) for reusability and readability       
  • Subdialogs – Calling another Studio application as a subroutine 
  • Application Transfers – Go to another Studio application without returning

Module 7: Event Handling: Adding event handling globally, in subflows, or element-level
