It472 week 4

DQ4:  Most business processes are too complex to be explained in one DFD. Most process
models are therefore composed of a set of DFDs. The first DFD provides a summary
of the overall system, with additional DFDs providing more and more detail about each
part of the overall business process. Thus, one important principle in process modeling
with DFDs is the decomposition of the business process into a hierarchy of DFDs,
with each level down the hierarchy representing less scope but more detail.

1) Define what is meant by a process in a process model. How should a process be named? What
information about a process should be stored in the CASE repository?

2) Discuss how the analyst knows how to stop decomposing the process model into more and more levels of detail. 

3) Suppose that your goal is to create a set of DFDs. How would you begin an interview with a knowledgeable user? How would you begin a JAD session?

HIT SYSTEMS PLANNING

  

HIT Systems Planning/Information Requirements

As the manager of CTU Health Care Systems, you have done your research on three vendors to which you would like to outsource the implementation of the electronic health records (EHRs) for the clinics. As the manager, you have a number of critical decisions regarding the electronic medical record systems. At first, you thought you could either implement the existing EHR system at the other acute care organization or implement an entirely new EHR in both facilities.

You met with your staff, and after researching several companies that offered both products and services, you have solicited request for proposals (RFPs) from the following three companies:

  • ABC      Systems Consulting, the leading company in health care systems integration      services, refused to bid on the systems integration required for bringing      the current EHR system into the other organization. This was because of      the risks and time requirements for designing, implementing, and testing      the large number of interfaces required and the required time line for the      completion of the project as identified by the client.
  • XYZ      EHR Systems proposed that its new, recently redeveloped EHR be implemented      in both facilities, which included a computerized physician order entry      (CPOE) module, standardized drug interaction alert functionality, and      customizable clinical alert functionality. It estimated that the merged      entity would get a much better price than $50 million for purchasing this      new system. Unfortunately, XYZ was unable to provide evidence of      successful installation of its recently redeveloped EHR system at a      similarly large delivery network or anywhere.
  • QRS      EHR Systems, a leading provider of EHR systems for large acute care      facilities, proposed that its EHR be installed in both acute care      organizations with a $50–60 million price tag. QRS included a CPOE module,      standardized drug interaction alert functionality, as well as      evidence-based clinical alert functionality. QRS also had a physician      office EHR system with an embedded patient registration system; however,      QRS has had minimal experience with integrating the physician office      registration system with the acute care (hospital) registration system—an      integration feature that was a priority for this project based on the      client’s information technology (IT) strategic plan.

The stakes surrounding your recommendation to the chief information officer (CIO) and chief executive officer (CEO) could not be higher in terms of dollars and your career.

Discuss the following in your paper of 3-4 pages, not including title page and reference page:

  • What      pieces of information are the most critical for your decision on selecting      the right vendor?
  • What      other options, if any, do you have?
  • What      are the critical success factors in the case?
  • What      are your recommendations to the CIO and CEO based on the RFPs that you      received?

The company has asked you to build

  

The company has asked you to build a prototype of an n-tier system using the Northwind database as an example. The company wants to be able to add, edit, and delete records from the customers, orders, order details, products, categories, and supplier’s tables. Your instructor will provide you the online link to the SQL Server database files (MDF and LDF).
Assignment Guidelines
• Create the Data Access tier and Data tier projects:
1. Create a class library project for the Data tier.
2. Add a new class library project the project created in Step 1 for the data access tier.
3. Add a typed DataSet using a new data source that connects to the Northwind sample database.
4. Select the database objects (customers, orders, order details, products, categories, and suppliers) tables.
5. Make sure the TableAdapters are stored in the Data Access tier and the DataSet class is added to the Data tier.
• Make sure that separate tiers are created for each layer by verifying that separate class libraries were created and the necessary references to the project were added.
•Using the project, you started in Week 2 Individual Project, verify the business logic layer (middle tier) is working correctly and make the connection to the database, implementing the logic in the data layer provided to manipulate the data stored in the database portion of the n-tier system.
Assignment Guidelines
• Add the following to the Phase 2 individual project:
o Add a new Windows Communication Foundation (WCF) service library project to the Phase 2 individual project to communicate with the Data Access tier.
o Add the necessary queries and methods to the table adapters that will return, add, edit, and delete the data from the tables specified in Phase 2.
o Add references in the Data Service to the Data tier and Data Access tier projects.
o Add methods to the Data Service class created in Step 1 that will call into the Data Access tier.
• Make sure that separate tiers are created for each layer by verifying that separate class libraries were created and the necessary references to the project were added.

  

Assignment4_1.java as the file name and Assignment4_1 as the class name – Write a console program with a static method printHello() (in addition to main() method which is also static) that prints out “Hello World”. Call that method from main(). Assignment4_2.java as the file name and Assignment4_2 as the class name – Write a console program with static method inc() that takes value of type int and returns that value increased by one. In main() method do the following: Ask a user to enter an integer value Call method inc() and pass user input (integer value) into that method Print returned result Assignment4_3.java as the file name and Assignment4_3 as the class name – Write a console program with static method inc() that takes value of type int and returns that value increased by one. In main() – public static void localModification(int a) { a++; } Call that method from main() while passing some integer value stored in a variable, for instance: public static void main(String[] args) { int A = 5; localModification(A); System.out.println(A); } Make sure that value of A, printed in main(), is not affected by local modification made within the localModification() method, i.e. value 5 is printed. Try to understand why. Task: Change declaration and/or implementation and/or call of the localModification() method, such that print statement in main() method prints incremented value, i.e. 6.
