E-R modeling technique is a :Options: Pick one correct answer from belowTop-down approachBottom-up approachLeft-right approachNone of the above

Analyzing the Question

To determine the correct answer regarding the E-R (Entity-Relationship) modeling technique, we need to understand its fundamental approach in database design.

Relevant Concepts

1. Top-down Approach: This involves starting with the high-level concept and breaking it down into smaller components.
2. Bottom-up Approach: This begins with specific details and builds up to a high-level concept.
3. Left-right Approach: This isn't a commonly recognized approach in E-R modeling.
4. None of the Above: This option implies that E-R modeling doesn't fit into the other categories.

Analysis

E-R modeling is primarily considered a top-down approach since it begins with identifying the overall structure and key entities in a system before detailing their attributes and relationships.

Verify and Summarize

After evaluating the options, it's clear that E-R modeling is about conceptualizing the database design from a high level to a more detailed structure.

Final Answer

Top-down approach
