The assessment 1 Context document Contains Additional Information Abou The assignment requires you to organize a relational database for employee information by representing entries as sets of tuples and analyzing relations and functions within this context. Specifically, you will create sample entries, examine the properties of binary relations derived from specific fields, determine if certain relations are functions, identify an appropriate unique key field, and describe a relation between two fields as a function, analyzing its properties.
Paper For Above instruction In the realm of relational databases, the foundational concept revolves around the organization of data in terms of relations and functions, represented as sets of tuples. A tuple is a finite ordered list of elements, which in databases corresponds to a single record or row. To exemplify, consider a database that stores employee information with six specific fields: firstName, lastName, SS#, age, yearsAtCompany, and phoneNumber. Creating sample data involves devising realistic or fabricated entries for three employees, which can be expressed as a set of three 6-tuples. For example: ("John", "Doe", "123-45-6789", 30, 5, "555-1234") ("Jane", "Smith", "987-65-4321", 25, 3, "555-5678") ("Alice", "Johnson", "555-55-5555", 40, 10, "555-8765") These entries collectively form a relation of degree 6 (or a 6-ary relation), since they encompass six fields per record, encapsulated as a set of six-tuples. Moving forward, focusing on two particular fields—firstName and lastName—enables the construction of a binary relation, which is a set of ordered 2-tuples, each pairing a firstName with a lastName from the database. This relation's properties such as symmetry, transitivity, and reflexivity can be evaluated through concrete examples. For instance, the relation R defined by: R = {("John", "Doe"), ("Jane", "Smith"), ("Alice", "Johnson")} would be considered symmetric if, whenever ("John", "Doe") is in R, ("Doe", "John") also belongs to R. Since the last name is generally not related to the first name in such a manner, R is not symmetric. Transitivity would require that if ("John", "Doe") and ("Doe", "Smith") are in R, then ("John", "Smith") should also be in R, which is not necessarily true. Lastly, R is reflexive if all individuals share their own
