1. List the advantages of a relational model specific to ACME Global Consulting.
Relational models can provide some very significant advantages over other methods. First, they are very easy to read due to the nature of two-dimensional tables. Columns and row format is straightforward and consists of a collection of similar data among rows that allow for the user to easily locate what they need.
One of the biggest advantages of the relational model of database design is that its foundation is formal mathematical theory. It allows its concepts to be defined and examined with great precision. In other systems, the calculations may need to be done separately prior to using the database.
2. Summarize in your own words the purpose of an E-R model specific to ACME Global Consulting.

The E-R model can provide ACME Global with a specific, but open-ended design that is tailored to the company’s needs. This also allows us to sketch the design of a database informally and incorporate changes in order to avoid problems later on. The E-R model allows for growth beyond its ideas at inception. It lays the groundwork for later database relational designs.

3. List and describe essential components of the model such as entities, attributes, keys, relationships, roles, and dependencies specific to ACME Global Consulting.

Entity: real-world object or thing with an independent existence and which is distinguishable from other objects. Examples are a person, car, customer, product, gene, book etc. Attributes: an entity is represented by a set of attributes (its descriptive properties), e.g., name, age, salary, price etc. Attribute values that describe each entity become a major part of the data eventually stored in a database. A key is a set of attributes for one entity set such that no two entities in this set agree on all the attributes of the key.
