Follow the steps to successfully fill out the Codd Rules form online.

1. Click the ‘Get Form’ button to access the form and open it in your preferred online document editor.
2. Begin with the first rule detailing the information rule, ensuring that you can articulate how all stored data corresponds to a specific table cell.
3. Move to the guaranteed access rule. Here, confirm that every data element can be accessed logically using the combination of table name, primary key, and attribute name.
4. Continue with the systematic treatment of NULL values. Provide examples of how NULL values can signify missing, unknown, or non-applicable data within your database design.
5. Describe the active online catalog rule, explaining how the database structure is documented in an online catalog accessible to authorized users.
6. For the comprehensive data sub-language rule, ensure you highlight the requirement for a support language that allows for data definition, manipulation, and transaction management.
7. Next, address the view updating rule, confirming that all theoretically updatable views must be executable within the system.
8. Discuss the high-level insert, update, and delete rule by specifying that operations must allow for batch modifications rather than single-row manipulations.
9. Clarify the physical data independence rule, indicating that applications should not be concerned with data's physical storage.
10. Explain the logical data independence rule, emphasizing that changes in logical structures do not affect user applications.
11. Present the integrity independence, highlighting how integrity constraints can be modified without impacting applications.
12. Conclude with the distribution independence rule, underscoring that users must interact with data as if it were all located in a single location.
13. Finally, ensure that once all sections are completed, you save your changes, and choose to download, print, or share the form as necessary.
