  • business rules compiler described hereafter automates rules processing and addresses dependencies between business rules, modifying the business logic is a fairly short and simple procedure. Rules are unordered, so the user does not have to be concerned with ordering when entering (or, more importantly, altering) rules.
  • Various different types of business rules are defined. The most important types for pu ⁇ oses of the present description are derivation rules, constraint rules and referential integrity rules.
  • Derivation rules define how a column's value is computed when a database update occurs. Derivations can be aggregations of child record values (sums or counts— min., max., etc.), replicates (copies) of parent record values, or formulas based on values of other columns in the same record.
  • a sum rule derives a parent column value by adding values of a specified column in related child data objects. A sum may be unconditional ("the total item amount is the sum of the individual item amounts") or conditional ("the customer balance is the sum of the unpaid orders," where unpaid is the condition).
  • a count rule derives a parent column value by counting the number of records in related child data objects (e.g., the number of unpaid orders). Like sums, counts can be unconditional or conditional.
  • Each derivation rule can cause other derivation rules to fire. That is, a change in dependent data may cause a derivation rule for "A" to fire, and since other derivations can be based on "A,” a "chain reaction” occurs. This cascading of rules enables complex, multi-data object update processing.
  • Constraint rules are used to enforce conditions (boolean expressions) that refer to multiple columns for data validation.
  • a constraint may refer to an account balance column, ActBalance, and a credit limit column, CreditLimit. Whenever one of these columns is updated, the constraint then validates the result (e.g., the update is rejected when the ActBalance > CreditLimit).
  • Constraints can refer to the results of derivation rules and can thus govern derived columns.
  • Referential integrity rules preserve relationships between data objects when updates occur.
  • a referential integrity rule may prevent parent update if children are present, prevent parent delete if children are present, prevent child insert/update if parent is not present, etc.
  • cascade referential integrity rules may be specified, including cascade update (update child foreign keys on parent update of primary key), cascade delete (delete children on parent delete), cascade insert (insert parent if none on child insert/update), and cascade nullify (null child foreign keys on parent delete).
  • Business rules may be specified in various different ways.
  • a Business Rules Designer provides a graphical user interface to define business logic in the form of declarative business rules. Referring to Figure 3, the Business Rules Designer may consist of several overlapping tab sheets used to define different types of business rules, and a Rule Builder tool used for graphically building expressions.
  • the Columns tab of the Business Rules Designer has a read-only grid of all the columns in a selected data object, with their column-level rule information. Rules are displayed within the grid but are not input directly into the grid.
  • the Derivation tab allows a user to enter rules that define how a column's value is derived when update occur. Various options may be selected from the derivation-type box. Types of derivations include sums and counts, parent replicates, formulas and defaults (described above). For sums and counts, two buttons are available, a browser button that invokes the Rules Builder, described hereafter, and a syntax checker button.
  • the Constraints tab allows the user to define data object-level constraints that enforce multiple-column conditions for data validation. This tab provides a grid that lists information for all constraints defined for the selected data object.
  • the Constraint Name field allows the user to specify a unique name for a constraint.
  • the Condition field allows the user to enter an expression describing the constraint's condition, optionally using the Rule Builder.
  • the Relationships tab provides information about parent-child relationships for the selected data object. This tab also allows the user to modify referential integrity rules.
  • a relationships outline lists the parent and child relationships for the selected data object, and lists the primary and foreign keys for each relationship. The user selects a relationship from this outline to modify its rules.
  • a referential integrity frame allows the user to modify the system's default referential integrity rules to preserve relationships between data objects when updates occur.
  • An Enforce referential integrity checkbox provides separate sets of referential integrity rule options buttons for parent updates, parent deletes, and child insert/updates.
  • the Events tab allows the user to inco ⁇ orate custom code into system-generated application code.
  • a grid lists a name and description for each business rule event defined for a selected data object.
  • Events may be of different types, e.g., an in-line trigger code event, a conditional action event, or a user-defined modification event. Of particular interest are conditional action events.
  • a conditional action event call a specified action (function or stored procedure) to be executed when a defined condition evaluates to true.
  • Condition/ Action box allows the user to enter an expression to specify the function or stored procedure to be executed and any arguments to be passed.
  • a Rule Builder tool may be used to complete these fields if desired.
  • a Rule Builder screen display is shown in Figure 7.
  • the Rule Builder is used to create expressions graphically.
  • the Rule Builder provides lists of columns, functions, and keywords, as well as buttons with expression elements.
  • the list of columns uses outline controls for explorer-like expansion of column information.
  • the list of functions includes built-in RDBMS functions and any custom functions such as stored procedures (2 tiered), or Java functions (3 tiered) that have been registered.
  • the user when entering conditional expressions for sum, count, column validation or constraint rules, etc., may select from the functions in the list box.
  • the list of functions is extensible; i.e., the user may define new functions as methods in Java, for example, and register those methods with an External Object Manager, after which they will be listed as functions in the list box for use within the Rules Builder.
  • the list of keywords includes Inserting, Updating, and ":Old".
  • the :Old keyword allows the user to differentiate between a changed column value and its value before the transaction that caused the change.
  • Defining business rules is basically the same whether a declarative approach or a procedural approach is followed, and involves identifying business functions and the requirements of those functions, then defining one or more rules that implement each requirement.
  • the main difference between the two approaches is that, in the declarative approach, designing the business logic rule is the implementation; i.e., declaring the rules allows the code to be automatically implemented.
  • the procedural approach such rules are, by contrast, merely an excellent specification for the code to be built by a programmer.
  • the business rules implementation process has two important characteristics.
  • rules are unordered: the system automatically detects rule dependencies and computes an order of execution that is correct and optimal. Optimization is repeated when rules are changed, so performance remains high over maintenance changes. In the same manner, ordering analysis assures that rule enforcement remains correct (i.e., independent data is calculated first).
  • rules are transaction-independent: the system automatically computes which transactions are affected by a rule and builds logic for those transactions to implement the rule. For example, a rule regarding customer balance is automatically reused for many transactions, e.g., insert orders, delete orders, pay orders, etc.
  • FIG. 9 a simplified block diagram is shown of a business rules compiler that automatically generates code to implement the foregoing business logic rules.
  • Input to the business rules compiler may be in the form of a Business Rules Report, an example of which is shown in Appendix A.
  • the business rules compiler is divided into four stages, a rule/ transaction mapping stage, a rule ordering stage, a rule optimization stage, and a rule targeting (code generation) stage. The operation of each of these stages will be described in turn.
  • the function of the rule/transaction mapping stage is to determine the conditions under which data changes must "chain" to fire dependent rules.
  • the attribute Amount has a Derivation Rule of Price times Quantity.
  • the rules compiler must generate code to recompute Amount if a transaction occurs in which updates are made to Price or Quantity.
  • the Customer Balance attribute's derivation depends on the Order's Amount and Paid attributes.
  • the system must detect transactions that alter an Order's Amount or Paid attribute, and recompute the Customer Balance.
  • the system must also detect transactions that insert Orders (increase the balance) or delete Orders (decrease the balance). While such transaction analysis may seem straightforward, it is a frequent source of error since the number of such cases to be analyzed is very large, and because changes to requirements result in subtle side-effects that render prior transaction analyses incorrect.
  • the rules ordering stage computes a correct order in which to perform the business logic operations identified during the rules mapping stage.
  • a dependency graph algorithm is used for this pu ⁇ ose.
  • the use of dependency graphs is well-known. Given a two-column table of derived and referenced attributes of the type described, the algorithm essentially looks for attributes that are referenced but are not themselves derived, i.e., attributes that appear on the left side of the table with no entries on the right side of the table. The corresponding derivation expression is then placed in order and removed wherever found from right side of the table, and the process is repeated. In this manner the table is progressively reduced.
  • A X*Y
  • B 5*A.
  • X and Y appear on the left side of the table with no entries in the right side of the table.
  • A is referenced but is derived. Since X and Y have no entries on the right side of the table, they are removed from the right side of the table. As a consequence, A then has no entries on the right side of the table and is therefore removed from the right side of the table and code is generated to derive it.
  • the rules mapping and rules ordering stages identify operations and an execution order to achieve correct results in accordance with the rules.
  • the optimization stage then computes an efficient implementation of these functionally correct operations. More particularly, Base Components (data objects physically residing on disk) provide insert(), update() and delete() methods which enforce Business Rules. This execution is highly optimized for good performance.
  • the system buffers updates made during a transaction and re-uses these cached data for subsequent processing.
  • updates to two items within the same order The first order update causes the order component to be retrieved and updated. Instead of saving the row to the database server, it is saved into cache.
  • the second order update may therefore update the cached row without retrieving the order.
  • the cached order row is the written to disk at the conclusion of Save All processing, when all rows have been processed.
  • Another optimization involves aggregation.
  • the customer balance may be defined as the sum of the unpaid orders. Assume that an order is changed, e.g., increased from 100 to 120.
  • An inefficient implementation of the foregoing rule would be to, whenever an order is changed, re-sum all of the unpaid orders. Instead, child objects generate adjustments to parent aggregate data in order to persistently maintain the aggregate data. Hence, when the order amount is increased from 100 to 120, 20 is added to the customer balance.
  • a further optimization involves rule by-pass. Because the business rules compiler analyzes all dependencies inferred by the rules, it can use this knowledge to build code that bypasses processing when underlying dependencies have not been affected. For example, altering an order's date requires no adjustment to the related customers balance. Similarly, altering an order ⁇ s date requires no re-validation of an existing customer number (i.e., referential integrity). Various other optimization may be performed.
  • the business rules compiler will have computed a correct and efficient order in which to enforce the business rules.
  • the rule targeting stage then generates actual code to enforce the business rules.
  • the code generation process may be better understood by considering what code needs to be generated for each of various kinds of rules, i.e., derivation rules, constraints, and referential integrity rules.
  • derivation rules may be based on formulas entered by the user or on aggregates or replicates.
  • the code generated is essentially of the form: IF any-referenced-attribute-changed THEN do ⁇ calculate drivation formula ⁇ .
  • Table 2 depicts the Requirements (bold text) and resultant rules (bulleted points) as they might have been conceived by a developer and entered into the system.
  • the circled numbers and arrows represent the rules that fire in response to the change, per the IF ⁇ reference fields changed > tests for each of the rules types described above. Recall that the order of firing (represented by the arrows) is made correct by the Dependency Graph Analysis described above.
  • the rules targeting stage In the case of aggregations, the rules targeting stage generates code to, if a "hot" field (i.e., a field referred to in a derivation rule) changed, get the appropriate related record and add a "delta" to the aggregate, then make the object update itself.
  • a "hot" field i.e., a field referred to in a derivation rule
  • the customer balance is the sum of the unpaid order s,o for example, the paid flag and the order amount are "hot.” If a paid flag is changed, then the customer balance is decreased by the corresponding order amount.
  • the rules targeting stage In the case of replicates, the rules targeting stage generates code to, if the replicate field is changed, copy a field to related fields. In the previous example, when an order is marked as paid, then order items belonging to that order may also be marked as paid.
  • the rules targeting stage In the case of constraints, the rules targeting stage generates code to check basic attributes. If a change satisfies a constraint, then the change is allowed. Otherwise, the change is not allowed, all partially complete updates are rolled back, and a message is returned to the client. Similarly in the case of referential integrity rules, the rules targeting stage generates code to check whether a change satisfies the rule. If a change satisfies the rule, then the change is allowed. Otherwise, the change is not allowed, and an error is signalled.
