1. Data type check= A data type check confirms that the data entered has the correct data type
2. Code check=A code check ensures that a field is selected from a valid list of values or follows certain formatting rules
3. Range Check=A range check will verify whether input data falls within a predefined range.
4. Format Check=Many data types follow a certain predefined format. A common use case is date columns that are stored in a fixed format like “YYYY-MM-DD” or “DD-MM-YYYY.” A data validation procedure that ensures dates are in the proper format helps maintain consistency across data and through time.
5. Consistency Check=A consistency check is a type of logical check that confirms the data’s been entered in a logically consistent way. An example is checking if the delivery date is after the shipping date for a parcel.
6. Uniqueness Check=Some data like IDs or e-mail addresses are unique by nature. A database should likely have unique entries on these fields. A uniqueness check ensures that an item is not entered multiple times into a database.
