Match the following benefits of naming conventions with their respective impacts:
Readability = Enhances the readability of databases for developers and administrators Maintainability = Simplifies the process of modifying and maintaining database structures Usability = Makes it easier to find, identify, and use specific objects in databases Collaboration = Facilitates collaboration among team members in database design
Match the following benefits of naming conventions with their primary advantages:
Readability = Makes databases easier to understand and navigate Maintainability = Simplifies the process of modifying and maintaining database structures Usability = Enhances the usability of databases by making it easier to find, identify, and use specific objects Collaboration = Facilitates collaboration among team members in database design
Match the following benefits of naming conventions with their impact on database development:
Readability = Enhances the readability of databases for developers and administrators Maintainability = Simplifies the process of modifying and maintaining database structures Usability = Makes it easier to find, identify, and use specific objects in databases Collaboration = Facilitates collaboration among team members in database design
Match the following principles of effective naming conventions with their descriptions:
Clarity and Simplicity = Use clear and concise names that accurately represent the object's purpose or functionality. Consistency = Maintain consistency in naming patterns throughout the database. Meaningfulness = Use meaningful names that convey the object's purpose or functionality. Standardization = Adhere to industry-recognized naming conventions whenever possible.
Match the following benefits of consistent naming conventions with their explanations:
Enhanced usability = Makes it easier for developers and administrators to understand and work with the database. Simplification of database structures = Contributes to the simplification of modifying and maintaining database structures. Self-documentation = Serves as self-documentation, providing additional information about the purpose and usage of database objects. Collaboration facilitation = Facilitates collaboration among team members in database design.
Match the following considerations for effective naming conventions with their explanations:
Context = Consider the context in which the object will be used. Use names that are relevant to the specific application or domain in which the database is used. Documentation = Document the naming conventions for reference, especially for complex or uncommon naming practices. This ensures clarity and understanding for all users. Avoidance of generic names = Use meaningful names that convey the object's purpose or functionality. Avoid generic or ambiguous names that provide little information. Consistency maintenance = Maintain consistency in naming patterns throughout the database. Use similar naming conventions for related objects and avoid introducing inconsistencies that can confuse developers.
Match the following attributes with their recommended actions in effective naming conventions:
hk_*** = Represents a hash key. It is recommended to use clear and concise names that accurately represent its purpose or functionality. gsr_rsrc = Represents Resource UUID.
