Primary use case: Performing product catalog queries.
Quality Attributes: Modifiability scenario relating to the ease of adding new external systems from product manufacturers.
Restriction: Use of Open Source libraries and tools.
The next step (4) indicates that we must choose design concepts to satisfy the drivers. Since there are modifiability scenarios and we are in an initial iteration of the design. In which we seek to create the high-level structuring of the system, the “layers” pattern is chosen as a design concept, which allows grouping unit kingdom phone number library general responsibilities of the system.

On the other hand the modules

design concept is chosen to group functionalities at the level of the different layers and support the chosen use case. Finally, we choose to apply the Inversion of Control pattern to connect the components that will be contain in the modules and facilitate the integration of new modules. This pattern is appli by introducing the “Spring” framework, which is open source.

Subsequently in step 5 we apply the design

concepts and assign responsibilities to the resulting elements. Figure 1 shows sensor data networks methodology for data a possible initial result of the architecture decomposition. During sensor data networks methodology for data this design step, in addition to applying the design concepts, responsibilities are assign to the identifi elements. Examples of responsibility assignments would be:

The integration layer will contain the set of elements that will taiwan lead allow the application to communicate with different external systems through different channels.
>The Catalog Interface module contains the components that allow the deployment of the screens associat with the product catalog query use case.
