Sequence Check - correct answer ✔✔ The control number flows sequentially and any sequence
or duplicated control numbers are rejected or noted on an exception report. For example,
invoices are numbered sequentially. The day's invoices begin with 12001 and end with 15045. If
any invoice larger than 15045 is encountered during processing, the invoice is rejected as an
invalid invoice number.
Limit check - correct answer ✔✔ Data should not exceed a predetermined amount. For
example, payroll checks should not exceed $4,000. If a check exceeds this amount, the data
would be rejected for further verification.
Range check - correct answer ✔✔ Data should be within a predetermined range of values. For
example, product type codes range from 100 to 250. Any code outside this range should be
rejected as an invalid product type.
Validity check - correct answer ✔✔ Programmed checking of the data validity in accordance
with predetermined criteria. For example, a payroll record contains a field for marital status and
the acceptable status codes are M or S. If any other code is entered, it should be rejected.
Reasonableness check - correct answer ✔✔ Input data are matched to predetermined
reasonable limits or occurrence rates. For example, a widget manufacturer usually receives
orders for no more than 20 widgets. If an order for more than 20 widgets is received, the
program should output a warning.
Table lookups - correct answer ✔✔ Input data comply with predetermined criteria maintained
in a computerized table of possible values. For example, the input clerk enters a city code of 1 to
10. This number corresponds with a computerized table that matches to a city name.
,Existence check - correct answer ✔✔ Data are entered correctly and agree with valid
predetermined criteria. For example, a valid transaction code must be entered in the
transaction code field.
Key verification - correct answer ✔✔ The keying process is repeated by a separate individual
using a machine that compares the original keystrokes to the repeated keystrokes. For example,
the worker number is keyed twice and compared to verify the keying process.
Check digit - correct answer ✔✔ A numeric value that has been calculated mathematically is
added to data to ensure that the original data have not been altered or incorrect.
Completeness check - correct answer ✔✔ A field should always contain data rather than zeros
or blanks. A check of each byte of that field should be performed to determine that some form
of data, not blanks or zeros, is present. For example, a worker number on a new employee
record is left blank. This is a key field, and the request would be rejected if left blank.
Duplicate check - correct answer ✔✔ New transactions are matched to those previously input
to ensure that they have not already been entered. For example, not paying a vendor invoice
twice.
Logical relationship check - correct answer ✔✔ If a particular condition is true, then one or
more additional conditions or data input relationships may be required to be true and consider
the input valid. For example, the hire date of an employee may be required to be more than 16
years past his date of birth.
< or > - correct answer ✔✔ Strictly less than or greater than
<= or >= - correct answer ✔✔ less/greater than or equal
= - correct answer ✔✔ equal
, <> - correct answer ✔✔ not equal
Is - correct answer ✔✔ Compares two object reference variables
& - correct answer ✔✔ concatenate
Logical AND - correct answer ✔✔ All conditions are true
Logical OR - correct answer ✔✔ At least one condition is true
Logical XOR - correct answer ✔✔ One and only one condition is true
Logical NOT - correct answer ✔✔ Condition is not true
Logical BETWEEN - correct answer ✔✔ Upper and lower range, be careful to ensure the upper
and lower limit are included if you want them to be
Object - correct answer ✔✔ Programming constructs that encapsulate data, behavior, and
identity. Object data is contained in the fields, properties, and events of the object, and object
behaviors are defined by the methods and interfaces of the object.
A combination of code and data that can be treated as a unit. An object can be a piece of an
application, like a control or a form. An entire app can be an object.
