The LeanApps Life insurance components are designed using the latest concept for a layered architecture system. The basic concept of Layered architecture is that parts of a total application can be easily and flexibly interchanged without affecting the overall performance of the system as a whole. Clear lines of demarcation are drawn between the presentation layer (the user interface), the business logic layer (business rules such as the functional checks, calculation methods and formulae) and the data management layer (data storage). It is therefore possible for several customers to develop differing user interfaces with the assurance that the functional checks and calculation rules being executed are the same, as each of these interfaces call the same component(s) from the business logic layer.
