BUSINESS RULES Properly document and verify all business rules with the end users. Ensure that all business rules are written precisely, clearly, and simply. The business rules must help identify entities, attributes, relationships, and constraints. Identify the source of all business rules, and ensure that each business rule is justified, dated, and signed off by an approving authority. DATA MODELING Naming Conventions: All names should be limited in length (database-dependent size). ENTITY NAMES: Should be nouns that are familiar to business and should be short and meaningful Should document abbreviations, synonyms, and aliases for each entity Should be unique within the model For composite entities, may include a combination of abbreviated names of the entities linked through the composite entity ATTRIBUTE NAMES: Should be unique within the entity Should use the entity abbreviation as a prefix Should be descriptive of the characteristic Should use suffixes such as _ID, _NUM, or _CODE for the PK attribute Should not be a reserved word Should not contain spaces or special characters such as @, !, or & RELATIONSHIP NAMES: Should be active or passive verbs that clearly indicate the nature of the relationship Entities: Each entity should represent a single subject. Each entity should represent a set of distinguishable entity instances. All entities should be in 3NF or higher. Any entities below 3NF should be justified. The granularity of the entity instance should be clearly defined. The PK is clearly defined and supports the selected data granularity. Attributes: Should be simple and single-valued (atomic data) Should document default values, constraints, synonyms, and aliases Derived attributes should be clearly identified and include source(s) Should not be redundant unless they are justified for transaction accuracy, performance, or maintaining a history Nonkey attributes must be fully dependent on the PK attribute Relationships: Should clearly identify relationship participants Should clearly define participation, connectivity, and document cardinality ER Model: Should be validated against expected processes: inserts, updates, and deletes Should evaluate where, when, and how to maintain a history Should not contain redundant relationships except as required (see Attributes) Should minimize data redundancy to ensure single-place updates Should conform to the minimal data rule: “All that is needed is there and all that is there is needed.” Data Modeling Checklist Copyright 2019 Cengage Learning.
