Data Type Check (Aiman)

2022-12-12 03:21:48 UTC

A data type check can test to ensure that a data item fits the required data type. For example, numeric field must have only numbers or numeric symbols, and an alphabetic field can contain only the characters A through Z or a to z.

Reasonableness check (KAREN)

2022-12-12 03:24:30 UTC

A reasonableness check would ensure that data meets the expected range, type, or value. It is a common-sense check that you can use to ensure that your data is what is expected. Of course, you must have a solid of what you expect the data to be.

Range Check & Limit Check (ARUL)

2022-12-12 03:26:06 UTC

Range Check = It performed on numbers to check they are within certain ranges. For example, a person age should be in the range of > 0 but < 120.

Limit Check = Performed on numbers to make sure that data is not above or below a specified limit. For examples, A learner driver's age must be >=17.

combination check (suwanni)

2022-12-12 03:28:52 UTC

A combination check is a Single Check followed by a Recurring Check.
type - Range Check. Format Check. Consistency Check.
A combination is a way of selecting items from a collection where the order of selection does not matter. Suppose we have a set of three numbers P, Q and R. Then in how many ways we can select two numbers from each set, is defined by combination.

BATCH CONTROLS EXAMPLE :

HASH TOTAL - a sum that is meaningless except for internal control purposes
RECORD COUNT - totals the number of source documents once

Validity check(ARIF)

2022-12-12 03:29:15 UTC

process of ensuring that a concept or construct is acceptable in the context of the process or system that it is to be used

Existence check

2022-12-12 03:29:33 UTC

The existence data rule definition logic checks whether anything exists in the source data.

INPUT TECHNOLOGY(KUGAN)

2022-12-12 03:43:55 UTC

Input device enables the user to send data, information, or control signals to a computer. The Central Processing Unit (CPU) of a computer receives the input and processes it to produce the output.
