REA modeling - ONLY FOR ULTIMATE GEEK

REA Model Project

Summer 2017

Continue with Techarati, Inc., a medium-sized computer retail sales company, and use the following

summary of the Revenue cycle to complete the requirements below.

Techarati sells computers, purchased from various vendors, to both individual and

business customers.

All customer orders are handled by a sales representative. Once inventory availability is

verified, the order is filled and shipped to the customer by a warehouse clerk. If the

entire order cannot be filled, the items which are available are shipped to the customer

and the remaining items are shipped when they become available.

Customers mail in their payment based on an individual invoice received for each

shipment which is due 30 days from the date the customer receives the order. Techarati

does not utilize monthly statements. All cash receipts are processed by a cash receipts

clerk and are deposited on a daily basis in the checking account.

Using the information provided for Techarati, Inc. prepare an REA Data Model for the Revenue Cycle,

including cardinalities using the guidelines and appropriate symbols as described in chapter 7 (17) of

the textbook. The REA model should be well-formatted, easy to follow, and include appropriate

cardinality notations. Prepare the REA model using LucidChart (submit as a pdf file). ALSO, create the

appropriate table structures (chapter 8 [18]) which would be implemented in a relational database for

this model. See the step-by-step guidelines on how to create an REA model in Lucid Chart with

cardinalities and how to add the tables in LucidChart.

Use the following format to create the table structures, similar to the approach used in class:

Table Name Primary Key Foreign Key(s) Other non-key

Attributes

…

Include at a minimum three non-key attributes for each table and at least 2 non-key attributes for M:N

tables. Indicate a primary key for each table, and include foreign keys as necessary.

NOTE: Include the table structures in the same file as the REA model...i.e. Submit ONLY one file for this

assignment. Submit the file on Blackboard using this assignment tool on or before the due date. This is

an INDIVIDUAL assignment.
