​Change is not always easy

Changing a system can be difficult for a variety of reasons:

– Users don’t like change (too often/at all)

– New systems might omit old features

– Old systems might be faster in certain circumstances – People find change complex

– From a technology perspective, change might lead to incompatibility

– There might be data loss during migration

– It might be expensive (either in terms of money or time)

– … the list goes on!

What is difference between Data verification, and validation?

 Verification: include double entry of data and correct entry of data according to source of data.

 Validation: include the integrity of data enter with reference to a particular variable.

​What is needed to create a database input form design?

A database is required to create a data capture form and its design. To create a database following are to be considered:

 Defining Data types of inputted data

 Table / entities and their relationships

 Declaration of Type of field for a particular data e.g. for true or false data we use Boolean as data type etc.

Data Types Example

Number / Integer #####.### (sales, purchases, etc.)

Text Alphabetical data

Boolean Yes/no, true/false, etc.

Currency $, GBP, PKR, SAR etc.

Object Images etc.

Validation Checks

Presence Check To check data has been entered or present in the field

Length Check To check data entered must not be too short or too long in the field

Range Check To check data entered is within the range in the field e.g. 70-100 etc.

Format Check To check data has been entered or present is in correct style or format e.g. S123 etc. is show one alphabet and 3 numbers always. Or DOB, MM-DD-YYYY etc.

Validation Checks

Type Check To check data has been entered or present is correct e.g. Alphabet in number field is not a correct data type in the field. Etc. (Character check or number check)

Look up check It check that data enter exists and is stored in the reference table data

Check Digit Its and extra digit is the answer of calculated number added same number e.g. ISBN etc
