COMP3760/6760: Enterprise Systems Integration - Business Process Modelling - IT Assignment Help

Assignment Task:

Background: LCPL, A SYDNEY-BASED COMPANY 

LCPL is an actual mining and construction enterprise headquartered in Sydney with more than 5000 employees across Australia. LCPL undertakes projects within the Asia-Pacific region, mainly in Australia and New Zealand. The company delivers projects for clients acrossthe infrastructure,resources, civil engineering, energy and telecommunications sectors. 

The Process: Oracle Primavera P6 

The Control and Planning group of LCPL provides systems and processes to manage and control projects.  

Oracle Primavera P6 is a project management tool managed by Group Operational Services (GOS) of the Control and Planning (CP) division of LCPL. Group Operational Services supports other business units through developing and maintaining control and planning standards and methodologies. 

All divisions within LCPL should use P6 for their project planning, update and control purposes. The GOS  supports all Oracle Primavera P6 users across the company through a defined process (figure 1). To support P6  users, the GOS cooperates with LCPL’s IT group to integrate the support process with the IT service deskfor  the company. The IT service desk uses IT Service Management (ITSM) help-desk software as a support tool to  log requests, changes and incidents.

Project Brief (4 marks) 

Provide a description on: the group meeting schedule or plan, each member’s role in the project, identifying risks  and ways to manage risks, ways to communicate between members, and a log recording each meeting,  discussion and dialogue between members in relation to the project. Note: all members need to contribute to the  project. The description and log need to be submitted together with the four tasks.  

Task 1 Web Service Design (4 marks) 

Suppose you are wrapping the GSO support process (figure 1) as a web service, which allows a user to create a  request for an incident raised. You are required to: 

• Identify the two necessary functions of this GSO service; 

• For each of the above functions, identify the input/output messages; 

• Use WSDL interface definition constructs to specify the above identified functions with input/output  messages. 

Task 2 XML Schema Design (4 marks) 

For the above input/output messages, write their XML Schemas. You need to include the following:

• Two different ways of specifying complex types, one is defined inside the element, the other defines a  complex type first, then (re-)uses it as a complex type of an element; 

• Use constraints on the values of a simple typed element, on the occurrence of elements;

• Pick up one xml schema, construct a sample xml document.  

Task 3 EAI and Database Integration (4 marks) 

Suppose LCPL’s head office in Sydney maintains a personnel database containing information such as Senior  Planners, Optimisation Manager, Planners, Site Engineer, Planning Manager, Scheduler, Systems Analyst and Business Analyst along with their detailed information. Other sites have their own databases containing information on projects undertaken, issues and incidents reported, changes made and staff in charge of issues to  be resolved etc. In order to support the need of business analysis, LCPL sees a need to integrate systems running  across Australia and New Zealand. The objective of business analysis is to allow managers to make better  decisions on the project chosen, supply management and human resource management.  

For example, suppose an applicant wishes to check the frequencies of various issues reported in the system and  the information on staff assigned to those issues. This request would actually require data from multiple disparate back-end systems and different sites. In this case, there is a need to decompose the request into  multiple requests to be sent to the different back-end database applications, gather the information sent back, and  assemble this information in the form of a single uniformed response (i.e. recompose).  

• Design simple database schemas for the above scenario and explain what kind of integration technique  you would use. Assume the back-end databases are relational. 

• Design and draw a tiered EAI system handling this situation whereby users gain direct access to business  applications and data.  

• Explain how queries will be decomposed and replies recomposed. You may make the necessary  assumptions. 

Task 4 Discussion 

“LCPL is an actual mining and construction enterprise headquartered in Sydney with more than 5000  employees across Australia. LCPL undertakes projects within the Asia-Pacific region, mainly in Australia and  New Zealand. The company delivers projects for clients across the infrastructure, resources, civil engineering,  energy and telecommunications sectors”, from this description we can image there are different systems implemented in different sites of LCPL. Use what you have learned in the unit to discuss the following: 

• The possible issues relating to integration (from different layers/aspects) using examples;

• The possible technologies potentially used to support system integration at various levels/aspects;

• The options and considerations of the technologies along with their advantages and disadvantages
