Explanation of Solution

c.

(1)

Organization needs 20 servers for 5 years.

For Buy-Alternative calculation:

The given inputs are,

  • Server cost is $2,500.
  • Software costs is $1,250.
  • Straight-line depreciation is 3 years.
  • Maintenance percentage is 3 %.

The formula to calculate the total buy payment is given below:

Total buy payment = Depreciation + Maintenance

For 1 year:

Server cost = Server cost × servers purchased

       = 2500 × 20

       = $50,000

Software cost = Software cost × servers purchased

           = 1250 × 20

           = $25,000

Depreciation1 = (Server1 cost + software1 cost) / Depreciation year

          = (50000 + 25000) / 3

          = $25,000

Interest Expense = Server cost × maintenance percentage

    = 50000 × 0.03

    = $1,500

Maintenance = Server cost × maintenance percentage

    = 50000 × 0.03

    = $1,500

Total buy payment = Depreciation + Maintenance

       = 25000 + 1500

       = $26,500

For 2 year:

Depreciation2 = Depreciation1

         = $25,000

Interest Expense = Server cost × maintenance percentage

    = 0 × 0.03

    = 0

Maintenance = Server cost × maintenance percentage

    = 50000 × 0.03

    = $1,500

Total buy payment = Depreciation + Maintenance

       = 25000 + 1500

       = $26,500

For 3 year:

Depreciation3 = Depreciation1

            = $25,000

Interest Expense = Server cost × maintenance percentage

    = 0 × 0.03

    = 0

Maintenance = Server cost × maintenance percentage

    = 50000 × 0.03

    = $1,500

Total buy payment = Depreciation + Maintenance

       = 25000 + 1500

       = $26,500

For 4 year:

Depreciation = (Server cost + software cost) / Depreciation year

          = (0 – 0)/3

          = 0

Interest Expense = Server cost × maintenance percentage

    = 0 × 0.03

    = 0

Maintenance = Server cost × maintenance percentage

    = 50000 × 0.03

    = $1,500

Total buy payment = Depreciation + Maintenance

       = 0 + 1500

       = $1,500

For 5 year:

Depreciation = (Server cost + software cost) / Depreciation year

          = (0 – 0)/3

          = 0

Interest Expense = Server cost × maintenance percentage

    = 0 × 0.03

    = 0

Maintenance = Server cost × maintenance percentage

    = 50000 × 0.03

    = $1,500

Total buy payment = Depreciation + Maintenance

       = 0 + 1500

       = $1,500

Total Server cost:

Total Server cost = Sum of the server cost for 5 years

    = 50000+0+0+0+0

    = $50,000

Total Software cost:

Total Software cost = Sum of the software cost for 5 years

        = 25000+0+0+0+0

        = $25,000

Total depreciation:

Total depreciation= Sum of the depreciation for 5 years

    = 25000+25000+25000+0+0

    = $75,000

Salvage value:

Salvage value = (Total Server cost + Total Software cost) – Total depreciation

= 50000+25000 – 75000

= $0.00

Total cost:

Sum of yearly costs less salvage value = sum of totals buy expenses for 5 years

  = 26,500 + 26,500 + 26,500 + 1,500 + 1,500

  = $82,500

Finally, the sum of the yearly costs less salvage value is,

Total = total cost – salvage value

          = 82,500 – 0.00

          = $82,500

Therefore, the sum of the yearly costs less salvage value for buy-alternative is “$82,500”.

For Lease-Alternative calculation:

The given inputs are,

  • The cost of 3 year lease is $285.
  • The cost of 2 year lease is $335.
  • The cost of 1 year lease is $415.
  • Discount for 20 to 30 computers is 5%.
  • Discount for 31 to 50 computers is 10%.

The formula to calculate the total lease payment is given below:

Total lease payment = (Payment for leased servers – Discount amount) × 12

For 1 year:

Payment for leased servers = Payment per unit × Servers leased

        = 285 × 20

        = 5700

Discount amount = Payment for leased servers × Discount

     = 5700 × 0.05

     = 285

Total lease payment = (Payment for leased servers – Discount amount) × 12

         = (5700 – 285) × 12

         = 5415 × 12

         = $64,980

For 2 year:

Payment for leased servers = Payment per unit × Servers leased

        = 285 × 20

        = 5700

Discount amount = Payment for leased servers × Discount

     = 5700 × 0.05

     = 285

Total lease payment = (Payment for leased servers – Discount amount) × 12

         = (5700 – 285) × 12

         = 5415 × 12

         = $64,980

For 3 year:

Payment for leased servers = Payment per unit × Servers leased

        = 285 × 20

        = 5700

Discount amount = Payment for leased servers × Discount

     = 5700 × 0.05

     = 285

Total lease payment = (Payment for leased servers – Discount amount) × 12

         = (5700 – 285) × 12

         = 5415 × 12

         = $64,980

For 4 year:

Payment for leased servers = Payment per unit × Servers leased

        = 335 × 20

        = 6700

Discount amount = Payment for leased servers × Discount

     = 6700 × 0.05

     = 335

Total lease payment = (Payment for leased servers – Discount amount) × 12

         = (6700 – 335) × 12

         = 6365 × 12

         = $76,380

For 5 year:

Payment for leased servers = Payment per unit × Servers leased

        = 335 × 20

        = 6700

Discount amount = Payment for leased servers × Discount

     = 6700 × 0.05

     = 335

Total lease payment = (Payment for leased servers – Discount amount) × 12

         = (6700 – 335) × 12

         = 6365 × 12

         = $76,380

Total cost:

Total = Sum of Lease payments for 5 years

= 64,980 + 64,980 + 64,980 + 76,380 + 76,380

= $347,700

Therefore, the sum of the yearly costs for lease-alternative is “$347,700”.

Interest Expense = (Server2 cost × maintenance percentage)

    = 50000× 0.03

    =$1,500

Maintenance = (Server1 cost × maintenance percentage) + (Server2 cost × maintenance percentage)

= (50000 × 0.03) + (50000 × 0.03)

          = 1500 + 1500

Finally, the sum of the yearly costs less salvage value is,

Total = total cost – salvage value

          = 162,000– 0.00

          = $162,000

Therefore, the sum of the yearly costs less salvage value for buy-alternative is “$162,000”.

Consider the following database for some store: Customers (cid, cname, city, discount)Agents (aid, aname, city, percent)Products (pid, pname, city, quantity, price)Orders (ordno, mon, cid, aid, pid, qty, dollars) The relation Customers records the ID (cid), name (cname), location (city) of each customer and a discount percentage (discount) for this customer. The relation Agents records the ID (aid), name (aname), location (city) of each agent and a transaction fee (percent) charged by this agent. The relation Products lists the ID (pid), name (pname), location (city), quantity and price of available products. And finally, the relation Orders contains a unique order number (ordno), the month (mon), customer (cid), agent (aid), product (pid), quantity (qty) of each order as well as the total value (dollars) of the transaction.   1. Express the following query in SQL (a) List customers (names) who do not have discounts but purchased at least one product of price greater than $50. (b) Find…

Express each of the following integrity constraints in SQL unless it is implied by the primary and foreign key constraint; if so, explain how it is implied. If the constraint cannot be expressed in SQL, say so. For each constraint, state what operations (inserts, deletes, and updates on specific relations) must be monitored to enforce the constraint.   (a) Every faculty member must teach at least two courses.
