03) CoolGen with .Net

 What about .Net with Cool:Gen 

.NET-based Web Services model describes the .NET standards for implementing Web Service applications that require access to distributed business logic and distributed or host data.

It has four layers Presentation Layer, Workflow Layer, Business Logic / Rule Layer and (Core) Data Layer.


The Presentation Layer is used for the user interface of the application. It receives data from the Workflow Layer and formats the information for display to the client device. This layer is also used for formatting the data submitted as input by a user to the Workflow Layer.


The Workflow Layer is like a traffic police that routes/manages specific requests made by the Presentation Layer by invoking specific components provided by the Business and Data Layers.


Business Logic / Rule Layer is where business type rules and data derivation is performed. Components in this layer are invoked from the Workflow Layer and optionally use data received from Data Layer components or from other Business Layer service components.


The Data Layer handles all (core) data activities, including creating, reading, updating, and deleting records. It is the only layer that knows the physical properties/location of the data.
