TITLE: Design of a Distributed System

INSTRUCTIONS

You have been hired to build a distributed data storage system for a property sales agency that will allow its employees to store, access and update property information. The agency also requires a facility which will allow customers to assess property information in this system via a web service.

Each property has the following five associated pieces of information which must be stored in the system:

1. Property unique ID.

2. Property owner.

3. Property number.

4. Property postcode.

5. Property price.

Part 1 -

Design and build the above distributed data storage system using a remote object paradigm which allows employees to perform the following tasks:

1. Search the current list of properties by price range or postcode.

2. Add a new property to the system by providing owner, number, postcode and price.

3. Delete an existing property from the system given its ID.

All data should be stored in remote objects and, for the purposes of this coursework, not written to external files such as text files.

Part 2 -

Design and build a SOAP web service which allows customers to search the properties currently in the distributed data storage system by price range or postcode.

For part 1:?Create an object with necessary data structures and methods. The data in the system must be consistent; for example, two properties must not have the same ID. Create a remote object which can be accessed by a client. Use a name server. Good system design (this includes annotating code in a manner which clearly explains design decisions).

For part 2:?Produce a SOAP web service that returns to a client. The SOAP server determines the correct information. This information is returned to a client. Good system design (this includes annotating code in a manner which clearly explains design decisions).
