- All table names are singular and lowercase
- All field names are lowercase
- Delimit each word in table and field name with an underscore (_). eg., grand_total
- Add a 3 letter lowercase prefix followed by an underscore (_) to each field name
- nuBuilder and DB Normalisation rules requires the use of a Primary Key (PK) for each table
- Suggested that the PK be the name of the table followed by an underscore (_) and the letters id. eg., person_id
- Suggested that the PK should be a varchar(25), as it will automatically be populated by nuBuilder using the function called nuID() (when filled out as suggested), unless the PK is an auto-incrementing number
- If a varchar(25) is used for the PK instead of a number it allows for better use of certain hash cookies such as #nu_browse_filter#
- Also suggested that Unique Indexes not be used, allowing internal validating rules to check for duplicates. This is because of the way the project implements checking for PK types
- Foreign Keys (FK) should bear the shortname of the table as a prefix followed by an underscore (_) and then the original parent table's PK it refers to
