Reusing Business Logic

Versata automatically reuses business logic. This is important to note because so many technologies claim to enable you to be able to reuse logic, but it's up to the programmer; it's not automatic.

You specify what you want, not how you do it. Going back to the prior examples, if you setup the account balance to be calculated as deposits minus withdrawals and bank charges, this calculation automatically gets reused across several transactions. For example, the transfer funds transaction uses this calculation twice for each account involved in the transaction - first to subtract the withdrawal in the "from" account and second to add the deposit to the "to" account. Versata builds a dependency tree and reuses this rule for every transaction that adjusts any of the variables in this rule or dependent rules. Reuse is automatic and ensured.

Versata also facilitates the reuse of business logic from multiple application front-ends or user interfaces. So, if you build the business logic to calculate the account balance, you can reuse this logic from your call center application, or your web internet site, or maybe via the telephone. Versata has products and integration toolkits to reuse business logic with HTML, Java applications, Java Server Pages (JSPs), XML, Web Services, Lotus Notes, and other front-ends or user interfaces.
