Chapter 17, Problem 9SA
Program Plan Intro
Organization of table in a
- The data present in a database is organized into one or more tables.
- Each of table would hold a collection of related data.
- The data present in a table is structured into rows as well as columns.
- A row denotes a complete set of information regarding single item.
- The data stored in row is been divided into columns.
- Each of the columns denotes individual piece of information about item.
- A table has a specified number of columns, but can have any number of rows.
- A data type is been assigned to columns in table.
- The column designated as primary key holds distinctive value for each row.
- A primary key denotes column used for identification of a certain row in a table.
- An error occurs when duplicate data is been stored in primary key column.

I would like to get help to resolve the following case
Last Chance Securities
The IT director opened the department staff meeting today by saying, "I've got some good news and
some bad news. The good news is that management approved the payroll system project this morning.
The new system will reduce clerical time and errors, improve morale in the payroll department, and avoid
possible fines and penalties for noncompliance. The bad news is that the system must be installed by
January 1st in order to meet new federal reporting rules, all expenses from now on must be approved in
advance, the system should have a modular design if possible, and the vice president of finance would
like to announce the new system in a year-end report if it is ready by mid-December."
Tasks
1. Why is it important to define the project scope? How would you define the scope of the payroll
project in this case?
2. Review each constraint and identify its characteristics: present versus future, internal versus exter-
nal, and mandatory versus desirable.

2. Signed Integers
Unsigned binary numbers work for natural numbers, but many calculations use negative
numbers as well. To deal with this, a number of different methods have been used to represent
signed numbers, but we will focus on two's complement, as it is the standard solution for
representing signed integers.
2.1 Two's complement
• Most significant bit has a negative value, all others are positive. So, the value of an n-digit
-2
two's complement number can be written as: Σ2 2¹ di 2n-1 dn
• Otherwise exactly the same as unsigned integers.
i=0
-
• A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1,
or 1 becomes 0) and then add 1 to the least significant bit.
• Addition is exactly the same as with an unsigned number.
2.2 Exercises
For questions 1-3, answer each one for the case of a two's complement number and an
unsigned number, indicating if it cannot be answered with a specific representation.

Unsigned Integers If we have an n-digit unsigned numeral dn-1d n-2...do in radix (or base) r, then the value of that numeral is n−1 r² di Σi=0 which is basically saying that instead of a 10's or 100's place we have an r's or r²'s place. For binary, decimal, and hex r equals 2, 10, and 16, respectively. Just a reminder that in order to write down a large number, we typically use the IEC or SI prefixing system: IEC: Ki = 210, Mi = 220, Gi = 230, Ti = 240, Pi = 250, Ei = 260, Zi = 270, Yi = 280; SI: K=103, M = 106, G = 109, T = 10¹², P = 1015, E = 10¹8, Z = 1021, Y = 1024. 1.1 Conversions a.
