It is possible to have a schema and a decomposition that were not produced by the process, are in BCNF, and are not lossless despite the BCNF method's assurance of lossless decomposition. Describe how a schema like this is broken down and provide an example.

The CAP theorem specification for a NoSQL database. What exactly are C and A, and why is it impossible to satisfy all of these requirements at the same time?

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).

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information.   Remember the ERD will eventually turn into the design for a database from a top down view.  Make sure you resolve any many to many conflicts.  Label an identifier or primary key and all pertinent attributes given.   If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity.  Therefore, all entities should end up with at least an identifier and another attribute that makes sense.  You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common.  Make sure you show entities, relationships, cardinality, and optionality.  Swing Jazz Club The Swing Jazz Club teaches swing and jazz dancing and offers both private and group lessons.  Swing Jazz charges $60 dollars per hour for a private lesson and $10 dollars per hour for a group lesson.…
