a)

Program Plan Intro

Creation of an information system:

To create an information system an initial study and following phases are need to be made by the designer because they will create an impact to the design of the database.

The information is collected in order to establish details about the entities, relationships among the entities generated.

Business rules that are shaped up through relationships, connectivity and cardinalities are being obtained and collected through designer.

Question that can be asked in order to create an information system:

The below are some of the sample questions that can impact the design of the database:

Is it required to develop the database for all departments at once or whether it is required to design and implement the database for one particular department?

What will the design approach required that could affect the process of designing?

What type of development is required, one module at a time or integrated system approaches (Example: Billing, production, shipping and inventory)?

What type of tracking system is required that is in terms of tracking the nuts and bolts through lot number, by shift, by production, by type or by department?

What type of tracking system is required for the suppliers of each batch that is in terms raw materials used in the production of the nuts and bolts?

Is it required to track the customer information regarding the receive summary of nuts and bolts based on batches?

What type of reporting system is required that is what type of reporting requirements are required and who requires the distribution report details needs to be specified?
Effect of the questions that are asked:

The answers to the above question affect the database design in conceptual and in logical way along with the implementation, testing made with the subsequent operations.

⚫ your circuit diagrams for your basic bricks, such as AND, OR, XOR gates and 1 bit multiplexers, ⚫ your circuit diagrams for your extended full adder, designed in Section 1 and ⚫ your circuit diagrams for your 8-bit arithmetical-logical unit, designed in Section 2. 1 An Extended Full Adder In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj, Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit outputs: sj, Cout and rout. The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only on t₁ and to in the first place: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…
