The document discusses Siebel eScript, a scripting language that can be used in Siebel applications. It provides two types of scripts: server scripts that run on the server and browser scripts that run in the browser. Siebel eScript allows access to system calls through objects and can be used for data validation, user interaction, and integration with external systems. The document provides guidelines and commands for using Siebel eScript and tips for optimizing scripts.

- 4. Siebel Script --outlying Types of Scripts: There are two types of scripting available: Server Scripts (eScript or SiebelVB) Execute on the server for web clients or on the client machine for mobile or dedicated web clients Browser Scripts (JavaScript) Downloaded to the client and are executed within the browser

- 8. When to use Data Validation: Complex and business object/component data relationship rules can be written User Interaction: Specific messages to users based on specific inputs – string concatenation is supported Integration: Transfer the data to and from the external system ,uses include calling a business service, workflow, etc

- 13. Tips and Tricks Scripts are always interpreted (all text in the script is parsed), use compact notation where possible (for example): if(foo == bar) doSomething(); Instead of if(foo == bar) { doSomething(); } Use “ elimination ” code to short circuit functions when not needed: if(isInDoItList(myval)) { longChunkOfCode(); }
- 14. Tips and Tricks When querying for a business component, activate all fields via the ActivateField() method prior to executing the query (this is well documented in Siebel Bookshelf). When querying for BCs try to use a “ForwardOnly” flag in the ExecuteQuery() method, this forces Siebel to create a forward only cursor which is more efficient than a bi-directional cursor. Be very careful with using “SetFieldValue” within a “PreSetFieldValue” event due to possible undesired recursion. You can’t throw an error message during the “OnLoad” logic of an applet, (the error goes nowhere).
Editor's Notes
- #2: Declarative alternative strong typing Support strong type and typeless variable Strong type –- compile time performance Typeless -- runtime
- #4: ECMA-262 Edition 4 You should regard coding as a last resort. Siebel Tools provides many ways to configure your Siebel application without coding, and these methods should be exhausted before you attempt to write your own code, for the following reasons: ■ Using Siebel Tools is easier than writing code. ■ More important, your code may not survive an upgrade. Customizations created directly in Siebel Tools are upgraded automatically when you upgrade your Siebel application, but code is not touched, and it may need to be reviewed following an upgrade. ■ Finally, declarative configuration through Siebel Tools results in better performance than implementing the same functionality through code.
