What are constraints and criterias?
A constraint "CONSTRAINS" what can be inserted in a field, or what is provided in a result set. As an example you can add a constraint to a field that says whatever data is inserted MUST be 10 characters in length. constraints format the existing system in an elucidating manner by enhancing or modifying the existing rules
What is structural constraints?
Structural constraints are set in place by a system or organization. This is based on rules that are to be followed as directed by the organization.
What is the difference between field level and record level validation rule?
The information entered and how the information is entered is a very dominate role in field/record level validation. However they share the same goal to enforce rules consistently, to write less code.
What are the substantive constraints in the Bill of rights?
The substantive constraints found in the Bill of Rights outline how much power the government actually has. One of these constraints is found in the rules for search and seizure.
What is field validation?
Field validation ensures that a program or form is using clean incorrect data. A set of validation rules are used to check data that is entered into a system before it is processed.
What methods would you use to maintain the integrity of the data in your database?
The use of Foreign key constraints together with the use of proper field formats and lenghths. You can also use defaults and rules.

What is data consistency constraints?
Data consistency constraints are rules that define the allowable values and relationships within a database to ensure that the data remains accurate and reliable. These constraints help maintain the quality and integrity of the data by preventing conflicting or incorrect information from being stored. Examples include primary key constraints, foreign key constraints, and unique constraints.
What is the name of The rules that ensure that data in related tables is not accidentally deleted or changed?
Constraints.
What are rules that the data entered by a user must follow in access?
Validation Rules
What kind of hockey rules was there when it was field hockey in Ireland?
It is a mixture of field hockey's rules and lacrosses rules.
What data validation can be used in a database?
A database is only as useful as the data it contains. Validation helps prevent invalid or inconsistent data from getting stored. At the most elementary level, it could be as simple are requiring a given element to only contain numerical data. More complex validation rules might entail a list of valid values, cross-field edits (if field A contains "xyz", then field B cannot contain "abc") and various more complex rules known as constraints (such as foreign key and NOT NULL rules.)
