Decision Tables and Trees |
PREVIOUS NEXT |
Business analysts, who are used to creating their business rules in table or tree format, can do so using the decision tables and decision trees provided by ILOG JRules. Decision tables and trees provide a concise view of a set of business rules in the form of a spreadsheet or tree structure that has flexible browsing and exploration capabilities. In this way you can view and manage large sets of business rules in the Rule Builder.
Decision tables are rules composed of rows and columns and are used to lay out in tabular form all possible situations which a business decision may encounter, and to specify which action to take in each of these situations. Decision trees provide the same functionality, but are composed of branches that have a root as their source, and branches that have a leaf as their end point. The table/tree contains all the conditions and their associated actions. If the objects in working memory match the pattern of conditions given in a specified row or branch, then the actions in this row/branch are performed.
Decision tables and trees are stored in the repository and have the same status as rules. As with business rules, decision tables and trees are translated into IRL before execution. To be able to create decision tables and trees you need the Decision Table and Decision Tree plug-ins active.
