The local community leader came up with the idea of a quick event wizard via which users can quickly organize an event (e.g., invite users and order all necessary snacks, drinks, and other products). The community leader already contacted a consultant for an initial sketch of a table that can store all relevant data. The consultant came up with the following relational schema for that table: event(id, user_id, date, inv_id, inv_confirmed, product, p_price, p_amount). In this relational schema, each event has a unique identifier id. Furthermore, the system keeps track of the user that organizes the event (user_id) and the date and time of the event (date). The system also keeps track of all invited guests. In specific, the systems keeps track, for each invited guest with identifier inv_id, whether that guest already confirmed its participation in the event (inv_confirmed). Finally, the system keeps tracks of all products, e.g., snacks and drinks, that need to be ordered to organize the event (product), the price of each of these products (p_price) and the amount required of each product (p_amount). Next, an example of an instance of this relational schema: id 1 1 1 1 2 2 user_id 1 1 1 1 1 1 date Nov. 3, 3am Nov. 3, 3am Nov. 3, 3am Nov. 3, 3am Dec. 5, 7pm Dec. 5, 7pm inv_id 2 3 2322 2 inv_confirmed product p_price_ p_amount chips $2 chips $2 cola $4 cola $4 $2 $4 yes no yes no no no chips cola 000021 8 8 The local community leader is not sure of the quality of this table, but has understood from the consultant that knowing the dependencies that hold on this table will help analyzing the quality of this table. Hence, the local community leader contacted you to determine all dependencies that hold on this table. Question 1. Provide a minimal cover of all realistic non-trivial functional dependencies that hold on the above relational schema. Argue, for each functional dependency, why this functional dependency hold. HINT: The local community leader only requires a minimal cover. Hence, there is no need for trivial functional dependencies and functional dependencies that can be derived from other functional dependencies. 2. Are there any other non-trivial dependencies that hold on this table? If so, provide an example of such a dependency and argue why this dependency holds. HINT: E.g., multi-valued dependencies, inclusion dependencies, or join dependencies.
