Business Logic in the Presentation Layer - Design Patterns on the Implementation of Business Logic on the Client-Side

Abstract: As a general rule of thumb, business logic in a multi-layered information system should be implemented in a dedicated domain layer and be separated from the presentation layer. Although this rule has demonstrated its validity, it restricts the options for designing information systems. At times, there may be good reasons to deploy some types of business logic locally in the presentation layer. This paper presents a collection of design patterns that address the forces of implementing business logic in the presentation layer in the context of an object-oriented business domain layer.
