The following Figure 2 shows an EER schema for a database that can be used to track sales at a car dealership. Map this schema into a relational data model, including all primary keys and referential integrity constraints (foreign keys). For the VEHICLE to CAR/TRUCK/SUV generalization, consider the four Step 8 options presented in the lecture notes for mapping specializations/generalizations. Show the relational schema design under each of those four options (8A, 8B, 8C, 8D).

Create a relational schema for this diagram
Relations describe the intersection between two axes, x and y. For example, a table (tuple) found in a database contains columns (attributes) and rows (records or observations). Database and Geospatial Mapping Application developers rely on tables and cartesian coordinate systems to adhere to the rules of relational database theory so that integrity in the location is preserved. Tables should only contain records that relate to the columns found in that table and the data domain determines what records should be stored in a given table. Database administrators can check for integrity in relationships within and between tables using structured query language (SQL). What other computer-science or IT jobs rely on relations?
translate the following ER diagram into the appropriate relational schema(s):
Produce a relational schema diagram that corresponds to the linked ER diagram for a database for the television show Saturday Night Live (SNL). Your relational schema diagram should include primary and foreign keys. Often-times in database system development, requirements will change after the conceptual data model has been drafted: in your rela- tional schema diagram, add the following three additional attributes: attribute “birth.date" for the relation schema Host; attribute “start.date" for the relation schema Writer; and attribute “salary" for relation schema Cast Member. Please refer back to the requirements in Question 6, for additional details that may constrain the design of the relational schema model. Use the tool linked to create an image. Hints: please carefully note that "rerun date", “address", and “phone" are multi-valued attributes; how would those be depicted in the relational schema diagram? Also, please carefully note the many-to-many relationships; how would those…
