Application Service Scenario

Develop a service-based distributed web application that is part of “OnlinePlant” system. It records all of the transactions (selling and buying) of different types of plants and keeps track of the number of plants available in store. The system user could sign in as a store employee (seller), buyer, or as a system administrator.

The system contains the following components: a web application with SOAP services for selling, buying and retrieval processes and a Restful service for viewing and searching the available plants in the store through a web client and SOAP client at the store employee (seller).

1.Phase 1 (client-side) [30 marks]

At phase 1, develop the client-side interface to ensure that SOAP services are accessed properly via a java application and RESTful service is accessed via a web browser

For store employee (seller) [10 Marks]

1.The employee should be able to issuing receipts either for the customers need to buy a plant or those need to retrieve plant details such as type of plant, name of plant, age of plant, and the prize.

For buyer [5 Marks]

1. The buyer should be able to view the plant details and place an order.

For system administrators: [15 Marks]

1.After a successful login process, system administrator should be able to view all available plants in the store.

2. System administrator should be able to search for a specific plant by name or by age or by price.

.

Hint: Provide the necessary attributes and GUI interfaces and use the necessary communicating protocol.

2.Phase 2 (Server-side service) [60 marks]

At phase 2, develop web-side services using the JAVA programming languages. For each task required in phase one, you should provide the appropriate service using JAVA and provide the required security for only Restful service to grant access only to authorized users. [15 Marks each]

Here are some details regarding the functionality of some services:

View all available plants in store: this service should retrieve available plants in store that exist in a file (JSON format) on the server side.

Add a transaction: this service should reduce the number of existing plants according to the applied transaction; modifying the JSON file accordingly. If the number of plants from a specific type of plant reached the lower limit of that plant, the plant details should be stored in an “fast_selling” file (JSON format).

Delete a transaction: this service should update the various associated file(s) after applying a retrieval request.

Search for plant in store: this service should enable the system administrator to search for plant in store by any of their attributes.

Hint:Use the appropriate presentation format to save and read the necessary attributes to and from file.

3.Phase 3 (Using Cloud services) [10 marks]

1.The system is to be deployed over the Cloud for saving organization the cost of servers and other equipment and make use of remote resources. Answer the following with justification: Which cloud deployment model should be used. [4 Marks]

2.Design an architecture for the above application services showing its components and interaction between the components. [6 Marks]
