The pandemic of coronavirus disease 2019 (COVID-19) in Malaysia was first detected on 25 January. Reported cases remained relatively low and largely confined to imported cases, until localised clusters began to emerge in March. To stem the number of new cases, the government imposed a Movement Control Order (MCO) starting March 18, 2020.

Assume that you have been appointed as a database designer for a Non-Governmental Organization (NGO) in your residence community. The NGO's main task is to gather information on the current situation of the pandemic in the local community during the MCO period. This includes information on the percentage of cases detected, the quarantine center provided as well as the services available to assist affected community members. The NGO is planning to implement a database system to manage all information to ensure community members are aware of current situations.

Therefore, as a database designer, you are required to propose a database design prior to its implementation by presenting the following:

1. Identify ALL possible entities that could exist in the business process (give suitable entity name), complete all the entities with suitable attributes together with assigned primary key. (Use your own assumption to determine the attributes.)
2. Identify ALL relationships, cardinality, and/or participation for each identified entity.
3. Draw an Entity Relationship Diagram (ERD) by clearly stating the relationships between entities, cardinalities and attributes with correct notation.
4. Based on ERD created in (c), convert it into relational schema. State the primary key and foreign key for each relational schema (relations).
5. Produce sample records for each relation (table) that observes the relational integrity rules. FIVE records per relations are enough.
6. Then, produce FIVE SQL queries that can be used to manipulate the data from each relation and show ALL the results from each of the queries. (The queries should include a simple query, query for sorting results, aggregate function, sub-queries and query to alter the existing tables.)

Note:

You are free to use any Databases Management System (DBMS) tool (using DDL SQL or GUI).

You should submit a printout (screen capture) of:

1. Each table which shows the table name, fields and sample records.
2. Each query in “SQL View”, so that the grader can see your SQL code.
3. The result of each query (in table format).

Marv Johnson, city manager of Filkburg, Virginia, wants to develop a better understanding of the factors that influence vehicles maintenance and costs. Mr. Johnson has data on 100 vehicles in the city’s vehicle fleet. The dependent variable is the annual maintenance cost per vehicle (MCOST). The independent variables include total vehicle mileage (TMILE), a dummy variable coded1 for emergency service vehicles and coded 0 for all other types of vehicles (VTYPE). Assist Mr. Johnson by generating a regression equation using these data. What substantive conclusions can be reached about factors that affect vehicle maintenance costs?

c. Net income before income tax of $150,000 is desired after covering $410,000 of fixed cost. What

minimum contribution margin ratio must be maintained if total sales revenue is to be $1,600,000?

d. Net income before income tax is 20% of sales revenue, the contribution margin ratio is 60%, and

the break-even dollar sales is $200,000. What is the amount of total revenue?

e. Total fixed cost is $350,000, variable cost per unit is $26, and unit sales price is $50. What dollar

sales volume will generate an after-tax net income of $60,000 when the income tax rate is 40%?

P6-10B. Break-Even and Net Income Planning Venice Company has recently leased facilities for the manu-

facture of a new product. Based on studies made by its accounting personnel, the following data are

available:

Estimated annual sales ........................................ 60,000 units

Estimated Costs Amount Unit Cost

Direct materials............................................... $ 870,000 $14.50

Direct labor .................................................. 750,000 12.50

Manufacturing overhead........................................ 384,000 6.40

Administrative expenses........................................ 228,000

3.80

Selling expenses are expected to be 20% of sales, and the selling price is $82 per unit. Ignore income

tax in this problem.

Required

administrative expenses are fixed but that other costs are variable.

b. What would net income before income tax be if 40,000 units were sold?

c. How many units must be sold to earn a net income before income tax of 10% of sales?

P6-11B. Multiple Product Break-Even and Net Income Planning Madison Company manufactures and

Required

Assume that total fixed cost is $324,800.

a. Compute the net income before income tax based on the sales volumes shown above.

b. Compute the break-even point in total dollars of revenue and in specific unit sales volume for

each product.

EXTENDING YOUR KNOWLEDGE

EYK6-1. Business Decision Case The following total cost data are for Ralston Manufacturing Company,

which has a normal capacity per period of 400,000 units of product that sell for $18 each. For the

foreseeable future, regular sales volume should continue at normal capacity of production.

Solution 6.1

y-intercept 5 Total fixed costs of $5.000

Slope 5 Variable cost per unit of approximately $0.50 per water bottle cage

Total cost 5 ($0.50 3 # of water bottle cages) 1 $5,000

$25,000 5 $0.50 3 40,000 1 $5,000

Direct materials. . . . . . . . . . . . . . . . . . . . . . . . . $1,720,000

Direct labor . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1,120,000

Variable overhead . . . . . . . . . . . . . . . . . . . . . . 560,000

Fixed overhead (Note 1). . . . . . . . . . . . . . . . . . 880,000

Selling expense (Note 2) . . . . . . . . . . . . . . . . . 720,000

Administrative expense (fixed) 200,000

$5,200,000

Notes:

1. Beyond normal capacity, fixed overhead cost increases $30,000 for each 20,000 units or fraction

thereof until a maximum capacity of 640,000 units is reached.

2. Selling expenses are a 10% sales commission. Ralston pays only one-half of the regular sales

commission rates on any sale of 20,000 or more units.

Ralston’s sales manager has received a special order for 48,000 units from a large discount chain at a

special price of $16 each, F.O.B. factory. The controller’s office has furnished the following additional

cost data related to the special order:

1. Changes in the product’s construction will reduce direct materials $1.80 per unit.

2. Special processing will add 25% to the per-unit direct labor costs.

3. Variable overhead will continue at the same proportion of direct labor costs.

4. Other costs should not be affected.

Required

a. Present an analysis supporting a decision to accept or reject the special order. Assume Ralston’s

regular sales are not affected by this special order.

b. What is the lowest unit sales price Ralston could receive and still make a before-tax profit of

$39,600 on the special order?
