In Week 1, you developed an initial idea to build a database.

You followed the systems development life cycle (SDLC) and got an idea to start with. Now, it is time to start building your database. What next?

The project description developed in W1 Assignment 3 is a first draft, so consider it a rough draft. This means that you should continue to develop your idea.

The next step is to select some nouns in your project description. For example, a project has invoices, invoice distributions, and suppliers as nouns. These nouns are entities, or tables, that would be used to create the E-R model. Then, the adjectives and verbs that describe the nouns would become the attributes, or columns.

Therefore, in the example that we considered, we might have the following entities and attributes: Invoices Invoice_Distributions Suppliers # Invoice_id # Invoice_distribution_id # Supplier_id Invoice_num Invoice_distribution_line_num Name Invoice_type Line_type Address Supplier_id Invoice_id

Using your knowledge of selecting entities and attributes, complete the following tasks for this week:

Review your project descriptions and come up with five entities and some attributes that describe the entities. Do not identify more than five attributes for each entity.

In a Microsoft Excel spreadsheet, define six columns (nouns) from the project description you submitted in W1 Assignment 3 that you consider key to your database.

These will be the tables for the database. Then, in the rows for each column, define the attributes (adjectives). You have taken your creative idea and started to move the nouns and adjectives you identified in a logical model-the E-R model.

This will give you a working outline of the tables that will be created in the final script. Assignment Deliverable After you complete the lab and course project, collate the information from both in a 3- to 4-page report in a Microsoft Word document.

What does the company have? What business projections does it have? Integration with other systems—plan how the current system can be integrated with other systems? Documentation and communication—describe how this vital part will be accomplished? Design for changes—prepare a plan for the future? Reusable resources The reusable resources need to meet the demands and the policies of the airline reservation system which includes all important details about system handling and then working over the ticket system. The airline involve money with documentation that includes the date of call and agent name as well. The focus is on the trip insurance that cover the airline tickets with some ticket values that can be salvaged. The covering of the change fees will generally cost less than insuring the entire ticket where the ticket can be reused for the penalty. The reuse of the resources can help in effectively working over the different methods and cover the expenses. Thank you for your support. I have received my work. It is up to the mark.

Outline the database you would like to create. The airline reservation system would require information about traveler that includes details like first name, last name, sex, date of birth etc. The information is about requesting for concessions and perks like giving the rewards to the fliers who are flying frequently in the particular month. The customer view with the needs hold the check on availability of flights and ticket pricing and concessions.

The normal process is followed till there is a manual filling of data and then processing it which could be used to cause a lot of inconvenience to administrator and customer. The use of database is mainly to facilitate the process with smooth reservations and fast ticket process with minimal work on the part of customer and the administrators. The database works on smooth reservation for airline tickets with minimal work that includes how the people are involved in it. Through this, the administrator, customer and broker are able to control information at different times. It includes the scheduling of flights with days and flights that have arrived. The list of passengers who are waiting in the given flight etc.
