Explain the value of utilizing the entity relationship model

The entity-relationship model (or ER model) is a way of graphically representing the logical relationships of entities (or objects) in order to create a database. This is also referred to as the data model.

Employing a data model permits the designer to present data visually. These models focus on representing the data in terms of a user’s viewpoint. During our discussion, let’s also consider not only the importance and advantages of data modeling but also do some web research regarding modeling tools.

Explain the value of utilizing the entity relationship model (ER Model) and the entity relationship diagram (ERD) for relational databases. Is this an advantage or disadvantage? Why?

….In other words why would anyone want to do data modeling?

What are the advantages of data modeling?

Cisneros & Imagery

Cisneros & Imagery

Images represent much more than the literal–they also suggest figurative meanings as well.   Images can describe setting and characters, creating mood and tone for understanding their significance.

Focusing on your favorite chapter, choose one image to analyze from Cisneros’ novel and write a persuasive critical reading response exploring its significance as it relates either to setting, character development, and/or major themes in the story.  Your response must contain a thesis statement—i .e., an original claim—and utilize evidence from the text, referencing page numbers so we can follow your argument.

Information Technology Project Management

Information Technology Project Management

PART 1.

Perform a financial analysis for a project using the format provided in Figure 4-5 in the text. Assume the project costs and benefits for this project are spread over four years as follows: Estimated costs are $200,000 in Year 1 and $30,000 each year in Years 2, 3, and 4. Estimated benefits are $0 in Year 1 and $100,000 each year in Years 2, 3, and 4. Use a 9% discount rate, and round the discount factors to two decimal places. Create a spreadsheet to calculate and clearly display the NPV, ROI, and year in which payback occurs. Based on the financial analysis, please write a few lines on the spreadsheet explaining whether you would recommend investing in this project. (Tip: Use the spreadsheet format given, such that Year 0 is year 1 described above. So your spreadsheet should include columns for years 0, 1, 2, and 3.)

 

PART 2.

Develop an imaginary project charter for a web development project. Assume you are going to develop a website from scratch for a small retail business of your choosing. Assume the web site will include a home page with links to information about products and services. It will also include a bulletin board, chat room, and provide information about the company and how to contact people in the company. Assume you are a self-employed software developer and your client is the owner and founder of the business. The owner wants a copy of the charter to circulate among her employees so they can be made aware of the project and prepare to support it. You may use Table 4-1 in the text as a template for creating headings and organizing information in the charter.

Explain the benefits of normalization

Explain the benefits of normalization

Question 1: Describe two ways redundancy infiltrates a database. Hint: Think about the difference between text boxes as data inputs and drop-down selection lists – one better controls the quality of data you enter! Another hint is to reflect on lookup tables. Note: Please do not state by “not normalizing the database”. Be more specific and creative!

Question 2: Explain one characteristic of a database that has data redundancy. Note: Redundancy in our context is not a good thing!

Question 3: Briefly explain the benefits of normalization and why we should implement it when designing databases

Question 4: Provide an example of a table or database that is in first normal form and explain how you would bring it to 3NF.
Solve these questions in details and provide examples to support your rationale.
