Rules can be collected through the requirements capture exercise.In evaluating the basics of data validation, generalizations can be made regarding the different types of validation, according to the scope, complexity, and purpose of the various validation operations to be carried out.

The simplest kind of data type validation verifies that the individual characters provided through user input are consistent with the expected characters of one or more known primitive data types; as defined in a programming language or data storage and retrieval mechanism as well as the specification of the following primitive data types: 1) integer; 2) float (decimal); or 3) string.(See also data type checks below)Checks for missing records.Numerical fields may be added together for all records in a batch.Data validation rules may be defined, designed and deployed, for example: Definition and design contexts: Data that does not conform to these rules will negatively affect business process execution.Therefore, data validation should start with business process definition and set of business rules within this process.Such complex processing may include the testing of conditional constraints for an entire complex data object or set of process operations within a system.

Checks to ascertain that only expected characters are present in a field.For example, an experienced user may enter a well-formed string that matches the specification for a valid e-mail address, as defined in RFC 5322 but that well-formed string might not actually correspond to a resolvable domain connected to an active e-mail account.Structured validation allows for the combination of any of various basic data type validation steps, along with more complex processing.A validation process involves two distinct steps: (a) Validation Check and (b) Post-Check action.The check step uses one or more computational rules (see section below) to determine if the data is valid.In modern Relational database values in two tables can be linked through foreign key and primary key.
