Answer : A, B, C, D

Question 3

A database that is growing at 100% per annum compound will be:

A4 times its original size at the end of year 2

B6 times its original size at the end of year 3

C2 times its original size at the end of year 5

D3 times its original size at the end of year 2

EHalf its original size at the end of year 2

Answer : A

A database growing at 100% per annum compound doubles in size each year, following the formula for compound growth: Size = Initial Size (1 + Growth Rate)^Years. For a 100% growth rate (1.0), after 2 years: Size = Initial Size (1 + 1)^2 = Initial Size 2^2 = 4 times the original size. The DAMA-DMBOK discusses capacity planning, noting that ''data growth projections, including compound growth, are critical for planning storage and performance requirements'' (DMBOK2, Chapter 10: Data Storage and Operations, p. 391).

Calculating for other options: After 3 years, the size is 2^3 = 8 times (not 6, so B is incorrect); after 5 years, it's 2^5 = 32 times (not 2, so C is incorrect); after 2 years, it's not 3 times (D) or half (E). Thus, A is correct.

Question 4

The purpose for adding redundancy to a data model (denormalisation) is to:

AMake it easier for developers to join tables

BAvoid the loss of data by storing key values more than once

CImprove aggregate database performance across read requests

DFully utilize all the indexes

EEnsure surrogate keys are retaining their unique values in all satellite tables

Answer : C

Question 5

Defining quality content requires understanding the context of its production and use, including:

AProducers

BTiming

CNone of the above

DDelivery

EConsumers

FFormat

Answer : A, B, D, E, F

Question 6

The process of identifying how different records may relate to a single entity is called:

AMeshing

BMunging

CMirroring

DMatching

EMangling

Answer : D

Identifying how records relate to a single entity, such as a customer, is called data matching, often used in data integration. The DAMA-DMBOK states: ''Data matching is the process of identifying and linking records that refer to the same entity across different sources, critical for master data management and integration'' (DMBOK2, Chapter 13: Data Integration and Interoperability, p. 515).

Options A, B, C, and E are incorrect: they are either not standard terms or unrelated to this process.

Question 7

Decentralized informality can be made more formal through a documented series of connections and accountabilities via a RACI matrix.

ATRUE

BFALSE

Answer : A
