Adobe InDesign CS2 @work: Projects You Can Use on the Job

This appendix contains a description of the Trader 2 stock trading application. Most of the components of this application were loaded into the WebSphere Studio Asset Analyzer database to demonstrate the functions and features of the product.

Application overview

The Trader 2 application is used to maintain a stock portfolio held by an individual.

This application enables you to:

• Obtain quotes (in batch mode, you list portfolios and their values)

• Buy more shares of a company’s stock

• Sell currently held shares of a company’s stock

The Trader application uses two data sources:

• Company data

• Customer data

The company file contains the stock name and the past week’s quotes. The customer file contains a record for each customer and company that they own, including the number of shares held.

For batch applications, there are example versions that use two VSAM files, two DB2 tables, or two IMS DB PSBs.

In the CICS application, the transaction input is taken directly from an online user’s interactions. In the batch application, the user’s input is replaced with a sequential file that contains several records that represent the day’s transactions.

Components of the Trader 2 application

We downloaded the components for the Trader 2 application from the Web and copied them into data sets based on the instructions found in Appendix C of Introduction to the IBM Application Development Tools for z/OS and OS/390, SG24-6887.

Table C-1 on page 187, Table C-2 on page 188, Table C-3 on page 189, Table C-4 on page 191, Table C-5 on page 192, and Table C-6 on page 192 list all of the components of the Trader 2 application that we loaded into the WSAA database for our demonstrations.

Figure C-1 on page 187, Figure C-2 on page 189, Figure C-3 on page 190, Figure C-4 on page 191, Figure C-5 on page 192, and Figure C-6 on page 193 depict how WSAA represents the information after it is loaded.
