              Explain business rules concepts<\/h2><\/span>\n

              * See Overview of Oracle Business Rules<\/a><\/p>\n

              What Are Business Rules (BRs)<\/h3><\/span>\n

              * BRs are statements that describe
              \n– business policies
              \n– key business decisions
              \n* BRs allow continuous changes without code recompiling (vs Coding)<\/p>\n

              Rules Expressions<\/h3><\/span>\n

              Rules can be expressed with two types:
              \n* IF THEN structure (condition and actions)
              \n* Decision table (spreadsheet like)<\/p>\n

              Conditions<\/h4><\/span>\n

              * IF<\/em> part of IF THEN structure
              \n* Refers to facts, e.g.<\/p>\n

              \r\nIF Rental_application.driver age < 21\r\n<\/pre>\n
              Actions<\/h4><\/span>\n
              * THEN<\/em> part of IF THEN structure
              \n* Actions can
              \n- CRUD facts
              \n* Actions are fired sequentially<\/em>, not in parallel<\/p>\n
              Rules Elements<\/h3><\/span>\n
              \"\"<\/a><\/h6><\/span>\n
              Facts<\/h4><\/span>\n
              * Facts are objects that rules reason on
              \n* Each fact is an instance<\/em> of fact type
              \n* Fact types can be imported using Rules Designer from
              \n- Java classes
              \n- XML schema
              \n- ADF-BC view objects
              \n- Oracle RL definitions<\/p>\n
              Properties<\/h4><\/span>\n
              * Properties have:
              \n- Name
              \n- Data type
              \n- Value<\/p>\n
              Bucketsets<\/h4><\/span>\n
              * A bucketset defines a list of values or a range of values of specific type
              \n* Can be associated with fact properties in rules or decision tables<\/p>\n
              Rulesets<\/h4><\/span>\n
              * Are containers for rules and decision tables, acting like namespaces or Java packages
              \n* Ruleset = Rules + decision tables<\/p>\n
              Decision Functions<\/h4><\/span>\n
              * Provide contracts or interfaces for invoking rules from Java or SOA
              \n* Consist of
              \n- Input fact types
              \n- Rulesets to run
              \n- Output fact types<\/p>\n
              Decision Points<\/h4><\/span>\n
              * Rules SDK provides decision point API to access and run rules or decision tables from Java applications<\/p>\n
              Dictionaries<\/h4><\/span>\n
              * Dictionaries are containers for
              \n- facts
              \n- functions
              \n- globals
              \n- bucketsets
              \n- links
              \n- decision functions
              \n- rulesets
              \n* Dictionary = Facts + Bucketsets + Rulesets
              \n* A dictionary is an XML file (with .rules extension) that stores applications
              \n- rulesets
              \n- data model
              \n* A dictionary can link to other dictionaries
              \n* Dictionary example:<\/p>\n

              * Design time:
              \n- BR Service Component: used in SOA
              \n- Rules SDK: used in Java
              \n* Run time:
              \n- SOA Composer Application: used to edit deployed rules dictionaries.<\/p>\n
              Business Rule Service Component<\/h4><\/span>\n
              * aka Decision Component
              \n* Supports the use of Oracle Business Rules in a SOA composite application.
              \n* Can be used within SOA composite to
              \n- Run business rules
              \n- Wire a BPEL component to BRs
              \n- Dynamic routing in Mediator
              \n- Advanced routing rules in Human Workflow
              \n* Initiated by a BPEL process service component
              \n* Rules are store in MDS<\/p>\n
              Describe the Oracle Business Rules architecture<\/h2><\/span>\n
              Describe Oracle Rules Engine<\/h2><\/span>\n
              Rules Engine Architecture<\/h3><\/span>\n
              * Contains
              \n- Rule-base
              \n- Working memory
              \n- Inference engine (RETE)
              \n* Is a forward-chaining rules-based system:
              \n- Facts cause rules to fire and firing rules can create more facts, which in turn can fire more rules.
              \n- This process is called an inference cycle.
