UI BEHAVIORS

Implementing desired business logic functionality. The desired business logic functionality may include a number of individual functions. A number of computer implemented modules are selected. Each module is configured to perform at least a portion of one of the individual functions. Additionally, each module includes a computer implemented interface for connecting to other modules. The implemented modules are connected to create a composite module. The composite module includes functionality for implementing the individual functions. The composite module includes computer implemented interfaces for connecting to other modules, including a UI module. As such, the composite module is reusable in implementing more complex functionality by being selected as a computer implemented module and being connected to other computer implemented modules. The composite module is agnostic to how a UI module exposes functionality to a user.
