Suggestions for condensing:
- Consider simplifying or summarizing the explanations in the "Understanding Different Types of Joins" section.
- Reduce the number of practical examples in the "Practical Examples of Joins in AEC Scenarios" section, possibly by combining similar examples.
- Streamline the "Combining Data from Multiple Tables" section by focusing on fewer concepts or removing less critical details.

Please regenerate the content with these suggestions in mind.
