    Match the following considerations for effective naming conventions with their explanations:

    <p>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.</p> Signup and view all the answers
