You recently started a new job working with databases. you receive training on maintaining the database from your boss, Gregor. gregor tells you that when a DBMS flags a deleted record, completeness.
A database is an organized collection of data that is stored and accessed electronically. Small databases can be stored on the file system, while large databases are hosted on computer clusters or cloud storage.
A database is an organized collection of structured information or data, usually stored electronically in a computer system. A database is typically controlled by a database management system (DBMS).
MySQL, SQL Server, MongoDB, Oracle Database, PostgreSQL, Informix, Sybase, etc. are examples of various databases. These modern databases are managed by a DBMS. Structured Query Language or SQL is better known and is used to manipulate data in databases.

If a policy change causes a Pareto improvement, is the outcome necessarily Pareto efficient if a policy change causes a Pareto improvement, then the outcome is not necessarily Pareto efficient this is because another change in the policy could cause another Pareto improvement.
A Pareto development is a development of a device whilst an alternative in the allocation of goods harms no person and advantages as a minimum one character. Pareto enhancements also are called "no-brainers" and are generally predicted to be rare, due to the plain and effective incentive to make any available Pareto development.
Factors that lie within the PPF display an inefficient or below-usage of resources – this is Pareto inefficient. A Pareto development way that output of both products can increase as we move from inside the PPF to factors at the PPF boundary.

Answer:
(b) 1440
Explanation:
As the coupon rate of 8% is greater than the yield to maturity (YTM) of 6% annually, the bond is selling at a premium. Hence, the bond will be called at the earliest i.e. 15 years.
Coupon = Call Price * Semi-annual coupon rate = X * [0.08 / 2] = X * 0.04
Yield to call = 6% annually = 3% semi-annually
Time = 15 years * 2 = 30
We know that,
Current Price of bond = Coupon * [1 - (1 + YTC)-call date] / YTC + Call Price / (1 + YTC)call date
- 1,722.25 = [X * 0.04] * [1 - (1 + 0.03)-30] / 0.03 + [X / (1 + 0.03)30]
- 1,722.25 = [X * 0.04] * 19.60 + [X * 0.41]
- 1,722.25 = X * [(0.04 * 19.60) + 0.41]
- X = 1,722.25 / 1.194
-
X=$ 1,442.42 \approx $ 1,440
Answer:
$55.134
Explanation:
Given
dividend paid on its stock = $8.25
Duration is next 13 years
P0 = dividend on its stock × (PVIFA of return on this stock,years)
Remember PVIF = (1 - (1 + r)^-n)/r
Where PVIFA = present value interest factor of annuity
r = interest rate per period
n = number of periods
Therefore
P0 = $8.25 × (PVIFA11.2%,13)
P0 = $55.134
Answer:
b. 5.27%
Explanation:
First, find the PV of the bond today. With a financial calculator, input the following and adjust the variables to semi-annual basis;
Face value; FV = 1000
Maturity of bond; N = 15*2 = 30
Semiannual coupon payment = (8.75%/2)*1000 = 43.75
Semi annual interest rate; I/Y = 3.25%
then compute Price; CPT PV= 1,213.547
Next, with the PV , compute the yield to call (I/Y) given 6 years;
Maturity of bond; N = 6*2 = 12
Semiannual coupon payment = (8.75%/2)*1000 = 43.75
Price; PV= -1,213.547
Face value; FV = 1,050
then compute Semiannual interest rate; CPT I/Y = 2.636%
Convert the semiannual rate to annual yield to call = 2.636*2 = 5.27%
