For a business or non-profit organization of your choice, use a graphics program to develop a data-flow diagram (DFD) of one of its main processes and an entity-relationship diagram showing the data within the scope of the system.

Download the free open-source program, Dia Diagram to create your DFD. You may also create a E-R diagram using ERDPlus to help you envision your DFD.

Dia Diagram saves natively in the proprietary. dia format. When you are finished with your DFD, save and submit your. dia file.

Part 2:

A project team has estimated the costs associated with the development and maintenance of a new system. One approach requires a more complete design and will result in a slightly higher design and implementation cost but a lower maintenance cost over the life of the system. The second approach cuts the design effort, saving some dollars but with a likely increase in maintenance cost. Enter the following data into the spreadsheet. Print the result.

Create a stacked bar chart that shows the total cost, including the design, implementation, and maintenance costs over an expected system life of seven years. Be sure that the chart has a title and that the costs are labeled on the chart.

Insert a text box and write a paragraph that recommends an approach to take and why.

Paste your chart into an MS Word file (.docx or. odt format) next to your recommendation paragraph.
