Represent the following statements as formulas of Predicate Calculus, stating the
intended interpretation of any predicates and constants that you use. You should
give two versions of each formula, one using the existential quantifier and one
using the universal quantifier .

ii. All novels are books.
iii. All novelists, poets and journalists are writers.
iv. Poets are not the only writers.

2. Martha Gellhorn was an American novelist and journalist.
3. Sylvia Plath was American and wrote a poem called Ariel.
4. Arundhati Roy is an Indian activist and novelist.

University Database  A prestigious university has recently implemented a consolidation strategy that will require it to centralize their student records. In order to move forward, the local university will need to develop a data model that will retain student records and perform various data extract transform and load (ETL) processes. Imagine that you have been …

Using these findings, write a three to four (3-4) page paper in which you: Analyze the university’s requirements and provide a proposal to organize all the required data elements. The proposal should include the following: Provide an Entity Relationship Model (ERM) that will describe the data structure that will store all data elements. Note: The graphically depicted solution is not included in the required page length. Describe any assumptions or limitations for each relationship. For example, professors are able to teach more than one course or students can only be enrolled in one program. Create the primary key and foreign keys using a UML Class diagram for each table. Suggest at least four (4) types of business intelligence reports that could help the university in course management, student enrollment, or historical tracking. Support your answer by providing specific business functions that these reports could assist executives of the university. As an alternative for development of the database, you are considering outsourcing the functions above. Research the Internet and other media sources for vendors who develop registrar and school management database systems. Read More »
