A program is to be developed to simulate the operations of a scientific calculator. List the facilities to be provided by this calculator. Analyze this using a DFD 0-level and 1-level diagram.

Explain coupling and cohesion with their types and significance in software design. Explain with examples.

Define cohesion and coupling. Explain various types of each of them.

What are the goals of good software design? Explain with examples.

Design the following for an 'E-commerce solution for an electronic products company' that gives choice to the users to select a/few product(s) from the available range, order them and allow to make the payments online:

(i) Design the DFDs (level-0, 1 and 2).
(ii) Prepare SRS document. List assumptions, if any.
(iii) Design an ER-diagram. List all the entities, attributes, key constraints and cordiality.
(iv) Draw a Gantt chart.
(v) Specify the s/w engineering pre-design which suits this application development.

Draw the context diagram and Level-1 DFD for the following Mail Order Processing System.

"HMV Records is a mail-order company that distributes CDs and tapes at discounted prices to record-club members. When an order processing clerk receives an order form, he verifies that the sender is a club member by checking the member file. If the sender is not a member, the clerk returns the order along with a membership application form. If the customer is a member, the clerk verifies the order item data by checking the Item file. Then the clerk enters the order data and saves it to the Daily Order file. The clerk also prints an invoice and shipping list for each order, which are forwarded to order fulfilment section."
