Using consistent naming conventions makes creating and maintaining a database easier and can earn extra marks on projects. The document lists the Leszynskil/Reddick naming conventions, which specify prefixes like "tbl" for tables, "qry" for queries, and "frm" for forms. Adhering to these or other naming conventions helps organize a database and clarify the purpose or type of different objects. More details on naming conventions can be found in the referenced book "Successful ICT Projects in Access".
