The Screen Builder system realizes a service supplementing the business applications (systems implemented in the ApPello Java Environment), making them more convenient to use and flexible in parameterisation. An important development objective was dynamic screen management, and well as the implementation of screen and data structures that can be freely parameterised by the users.

The service was also implemented, among others, in the ApPello Loan Management, Credit Scoring and Collateral Management systems.

The purpose of the Posting Engine is to assist in the handling and execution of orders and transaction processes arising in any transaction system, with a view to the following:

• Possibility to interface with any input or output module,
• Customisable functions in the module,
• Ability to clearly separate the operational and the business logic

During the introduction of the service oriented architecture (SOA), ApPello rationalized the components of similar functionality in the various transaction modules. The Document Management module, an integral part of which is the template-based document generation, is the result of this process.

In the implementation outlined above, the Document Management system serves the needs of the ApPello business modules with respect to various documents, forms and reports.

The ApPello Account Module is a generic, service based system, which is easy to integrate into any banking environment and ensures the simple handling of accounts and balances. The solution has a widespread – and freely expandable - functionality regarding the handling of accounts and interests, the close of day functions and other connecting accounting and back-office activities.

The purpose of the Fee Handling module is to carry out fee calculations and their posting to the general ledger for the related business modules (e.g. Loan Management, Branch Teller), that require to do so as a consequence of the events entered. Using this module, the fees linked to various events arising in different modules can be handled and maintained in a unified way.

The module can prepare account-statements, credit and deposit summary information or invoices of the Bank's services in a very flexible way with easy data aggregation possibilities.

The statements can be generated based on templates, in the form of the Bank's style sheet. It also helps in providing statements in electronic format, reprint the statements, handle the format of the envelope machines and add various (e.g.: marketing) information.
