The image contains an Entity-Relationship (ER) diagram for designing a database system, possibly for a hospital setting. Here's a detailed transcription and explanation:### Entities and Attributes1. **Patient** - Attributes: - `ID` - `admit_date`2. **Physician** - Attributes: - `SSN` - `name` - `address` - `phone`3. **Room** - Attributes: - `Room_id`4. **Bed** - Attributes: - `bed#` - Under the category of `bed`, there is a specialization into: - **ICU bed** - **Regular bed**5. **Out Patient** - Attributes: - `Checkback_date`6. **Resident Patient** - Attributes: - `discharge_date`### Relationships- **Responsible**: Connects `Patient` to `Physician`. This indicates which physician is responsible for a given patient.- **Assigned**: Connects `Room` to `Bed`, where each room can have zero to two beds (noted as 0..2), and each bed can be assigned to exactly one room.- **ISA Relationships**: - Between `Patient` and its subtypes categorized as `Out Patient` and `Resident Patient` with conditions `{disjoint, complete}` indicating that a patient can only belong to one of these subcategories and every patient must belong to one. - Between `Bed` and its subtypes `ICU bed` and `Regular bed`, also with `{disjoint, complete}`, indicating similar exclusivity and completeness.### InstructionsThe instruction provided is: "Provide a complete Relational Schema of the database described by the following Entity Relationship diagram. You must use Merge Rule whenever possible." This calls for translating this ER diagram into a relational schema, optimizing by merging tables where appropriate using rules of database normalization and merger of entities/attributes in relational database design.

Below is the relational schema for the above entity relation diagram. The schema contains the name…

Your job as a database designer is to design a database with a schema that captures all the information that galleries need to maintain. Galleries keep information about artists, their names (which are unique), birthplaces, age, and style of art. For each piece of artwork, the artist, the year it was made, its unique title, its type of art (e.g., painting, photograph, sculpture), and its price must be stored. Pieces of artwork also classified into groups of various kinds, for example, portraits, still lives, works by Picasso, or works of the 19th century; a given piece may belong to more than one group. Each group is identified by a name (like those just given) that describes the group and property. Finally, galleries keep information about customers. For each customer, galleries keep that person’s unique ID, name, address, total amount of dollars spent in the gallery, and the artists and groups of art that the customer tends to like. Draw the ER diagram for the database.
