ERD CASE
A company has several departments. Each department has a supervisor and at
least one employee. Employees must be assigned to at least one, but possibly
more departments. At least one employee is assigned to a project, but an
employee may be on vacation and not assigned to any projects. The important
data fields are the names of the departments, projects, supervisors and
employees, as well as the supervisor and employee number and a unique
project number.
You are required to:
1. Create an ERD with cardinality notation.(Use MS Word save as: LastnameERD.doc)
2. Create 3NF table designs. (Use MS Word put in : LasnameERD.doc)
This process has two steps:
1. Convert the ERD into tables expressed using "Standard Notation Format"
2. Ensure that the tables are in 3NF.
3. Use MS Access to design the table. Create relationships.
4. Populate the table.

CBA Lab Exercise
CBA Laboratory Exercise
The new proposed automated cashiering and inventory system of G-Mall requires php 500,000 development cost. The determined economic life of the new system will be 5 years. Once the development is finished, the company will need to spend php 100, 000 for the employees training. The personnel salaries are estimated to php 500,000 per annum. The software lease (including license fee) will cost php100, 000 per year. In-house maintenance during operation will incur php 50,000.
G-mall still has old unused PC’s that can be used instead of buying brand new that will save them php 60, 000. It is expected that employees will be reduced by 50% thus saving php 500, 000 from personnel salaries and fringe benefits. Supplies and utilities will decrease saving php 36, 000.
All estimates of costs and benefits are increasing at a rate of 5% per year for both the current and new systems. The required rate of return for the company is 10%.
Instructions:
Use excel program in making your cost and analysis. Save your file as Lastname_CBA.xls. Your answers will be checked after 1 hour. Upload you xls file in yahoo groups.
1. Considering the scenario given identify and get the total of the following:
Costs
Non Recurring Cost
Recurring Cost
Benefits
Non Recurring Benefits
Recurring Benefits
* Use Sheet1 in excel for your table.
