26. Steps for Building an IT Application Prototype 1. Build a table for each table defined using the REAL model, 2. Build a menu system that has the following choices: Record Event Data, Maintain Data, Reports, and Exit. 3. Develop the necessary forms and procedures to collect event data and store it in the appropriate tables. 4. Develop the necessary forms and procedures to maintain the resource, agent, and location tables. 5. Develop queries required to generate desired information. 6. Develop report formats for each report. 7. Write the procedures required to execute the queries and format the reports. 8. Link each recording, maintaining, and reporting form to the application menu defined in step 2. Each form becomes a choice under either the Record Event Data, Maintenance, or Reports menu options.
