Transfer the following verbal description into an ER diagram: 1. A group (gourp-ID) has several companies (comp-ID), whereas a company belongs to one group.

Sure, I can help you with that! Here is the ER diagram based on the verbal description you provided:

  +-----------+           +-------------+
  |   Group   |           |   Company   |
  +-----------+           +-------------+
  | group_id  |<--------o| comp_id     |
  |           |           |             |
  +-----------+           +-------------+

Explanation:

- There are two entities: `Group` and `Company`.
- Each `Group` has one or more `Company`(ies).
- Each `Company` belongs to exactly one `Group`.
- The relationship between `Group` and `Company` is one-to-many, indicated by the `o` symbol near `Company`.

I hope this helps! Let me know if you have any more questions.
