What is a surrogate key, and why might it be used in data modeling?
A data model is a collection of data description constructs. The main purpose of a data modeling is to assist in the understanding of the meaning (semantics) of the data and facilitate communication about the information requirements. Discuss FIVE (5) evaluation criteria for a good data model.
[Hint: As a database designer, you have to interview customers, you are required to include questions you may ask to customers in your answers]

- When translating an ER model into database tables a.) all of the entity attributes become the foreign keys. b.) the entity attributes become the tables. c.) for each entity, two tables need to be created. d.) the entity attributes become the fields of the new table. The goal of normalization is to, (please select all that apply): a.) eliminate data duplication. b.) is create only 1:N relationships. c.) to create as few as possible tables to promote efficiency between the tables. d.) construct tables so that each table has a single topic or theme.arrow_forwardFor questions 1 through 3, state whether the statements are True or False (Do not provide anyexplanation or comment but only an answer of either True or False): 1. “Logical data model” is another term for requirements visualization.2.

Things to be considered in the applications to be developed: Creating a model with at least 15 tables for vaccination tracking system. The characteristics and relationships of the tables are in the model. Step by step analysis of the normalization steps for a table with multiple relationships in the model. It will briefly be stated which entity-tables will be used for what purpose. Only special rules will be added in the relational data model that cannot be directly specified.arrow_forward
