Question 10

Steps 4 and 5: Data Strategy Risks and Controls

These data risks can be controlled by comparing the extracted data to the source invoice and collection documents.

Possible risks involving the management’s estimates of bad debt percentages include human bias embedded in the authorized bad debt percentages, changes in customer payment behavior, and business process changes to credit customer approvals and collection practices.

Question 11

Steps 4 and 5: Data Strategy Risks and Controls

One way to control for these risks is to ask the finance, sales, and accounts receivable managers if there were changes to the customer base, market conditions, or business policies and procedures for credit approval, write-offs, or collection policies during the year. This knowledge could confirm existing bad debt percentages or motivate their adjustment.

Another control for evaluating the risks in management estimates and assumptions is to compare 1) c___t data to p___ y__ data.

A missing instance such as a missing sales transaction can be identified with gap analysis. If there is a sequential number for each sales invoice, then a missing number might indicate a sale that occurred but was not recorded. 2. A missing value occurs when the 3) tra___ is recorded, but we 4) __ n___ have information for all 5) cha__. (we have some info, but not complete) The result is empty cells. This might happen if a customer is recorded, but the record does not include the customer’s email address. The term null typically indicates a missing or unknown value.

Question 170

Data Preparation Pattern 9: Incomplete Values There are a few dimensions of incompleteness worth exploring: 1. Should null values be allowed, and if not, are there any? 2. If null values are allowed, what percentage of the values are null? If the percentage is high, should the column be loaded? 3. How are incomplete values represented: nulls, or a specific code? Are the representations consistent?

Question 171

Data Preparation Pattern 9: Incomplete Values -Remove the Column or Replace the Null Values The correction scenario depends on the situation. If null values are not allowed but they exist, they should be 1) re__ If the number of null values is too high to be useful, then 2) re___ the column from the analytical database. If there is inconsistency in representing missing values, design a 3) co___t schema and 4) co__ the values in terms of that schema

Answer 171

1) replaced 2) remove 3) consistent 4) correct

However, the values of age change when time passes and the data will become inconsistent. Therefore, instead of transferring age from the data source, it should be calculated as part of the analytical database.

Question 183

Data Preparation Pattern 13: Redundant Content Across Columns -Perform Column-By-Column Comparisons Performing column-by-column comparisons for 1) ov__ or de___s would 2) d__ this issue. Doing so within the Beans data set would show there is currently no redundant content.

6.2 Which Patterns Implement Information Modeling Algorithms?

Question 232

Information Modeling Pattern 1: Within-Table Numeric Calculation The within-table numeric calculation pattern creates a new 1) fi__ (a 2) cal__ column) from 3) o__ or __ nu__columns, or fields in the 4) s__ table. Basic 5) ari___ operations of addition, subtraction, multiplication, and division can do this A typical EX is determining the dollar total for an order line or invoice line by multiplying price and quantity

Answer 232

1) field 2) calculated 3) one or more numeric 4) same 5) arithmetic

Question 233

Information Modeling Pattern 2: Within-Table Text Calculation The second implementation pattern also involves creating a 0) n___ cal___ col__ from o__ or more fi___s in the sa__ table. However, the information in the new column is created from 1) t__ f__ For example, different pieces of location information could be linked, or concatenated, into an address so it can be read by a map service such as Bing Maps or Google Maps

Answer 233

0) new calculated column from one or more fields in the same table. 1) text fields

Answer 234

0) classification 1) unlimited 1.1) determined 2) part 3) same table 4) Boolean logic

Question 235

Answer 235

1) properly 2) relationships 3) tables 4) nature 5) relationship 6) type 7) join 8) cardinalities 9) 1-1, 1-N, N-1, or N-N?

Question 236

Information Modeling Pattern 4: Across-Table Calculation The calculations for this pattern are like the first three–a new column is created from existing data using 1) ari___, te__ cal___, or cla___ But this pattern is different from the earlier patterns because data from 2) dif__nt tables are used to create a 3) n__ co__n. This means the tables 3.1) m__ be 4) li__. How this is accomplished depends on the 5) sof__ being used

Answer 236

1) arithmetic, text calculation, or classification. 2) different 3) new column 3.1) must 4) linked 5) software

Answer 237

1) single-column 2) first to focus 3) measures 3) heart 4) aggregates 5) sliced, or broken down,

Question 238

In its simplest form, a measure applies a mathematical operation to all the values of a single column. Operations that can be applied include aggregate functions such as SUM, AVERAGE, COUNT, MIN, and MAX. Each of these functions generate a single value

Question 239

Information Modeling Pattern 5: Single-Column Aggregation For most applications, single-column measures make up a significant part of the information model. A few more things about aggregation functions: Except for aggregation functions that count, most require a numeric data type. Be sure to understand how the aggregate functions deal with specific values, such as null, as this can differ depending on the implementation platform.

6.3 Which Patterns Help Develop and Implement Accounting Information Models?

Question 244

Information Modeling Pattern 8: How Many Tables usually describe concepts like 1) c___s, ve___, sa___, and p___ts. The next pattern creates a measure that 2) c___s the number of 3) r___s or instances, of a concept within a table. This pattern can count 4) re___, tr___s, and a__s, which means it can be used for both 5) fa__ (tra___s) and di___n (re___s and a__s) tables.

Answer 244

1) customers, vendors, sales, and products 2) count 3) rows 4) resources, transactions, and agents 5) fact (transactions) and dimension (resources and agents

Question 245

Information Model Transactions: how many sales Agents (who): ho. many customers Resources (what): how many products does KLUB have

Question 246

Information Modeling Pattern 9: Participates | Transaction-Who The participates relationship describes 1) w__ is 2) inv__d in a transaction

Answer 246

1) who 2) invovled

Question 247

In KLUB’s data model there are three participates relationships: From Sales to Customer (the customer is an external agent). From Sales to Employee (the employee is an internal agent). From Purchases to Vendor (the vendor is an external agent). There are also other types of participates relationships that do not appear in the KLUB data set: CashReceipts to Customer. CashReceipts to Employee. CashDisbursements to Vendor. CashDisbursements to Employee. Because the information captured by these relationships is similar, the same types of analyses apply to all of them.

Answer 247

Question 248

1) what is involved 2) increase or a decrease 3) resources

Question 249

Information Modeling Pattern 10: Flows | Transaction-What In KLUB’s data model there are two flows relationships: From Sales to Merchandise. From Purchases to Merchandise. There are also other types of flows relationships that do not appear in the KLUB data set: Cash Receipts to Cash. Cash Disbursements to Cash. Because the information captured by these relationships is similar, the same types of analysis apply to all of them.

Answer 249
