What is physical independence? Physical independence is a condition in which the physical model can be changed without affecting the internal model. Also called the associative or attribute-value data model. It makes use of shared-nothing commodity computersMost (but not all) NoSQL systems (Use a Crow's Foot ERD to illustrate connectivity.). Describe the basic features of the relational data model and discuss their importance to the end user and the designer. Why is an object said to have greater semantic content than an entity? But. Translator training is one of the most important analytics investments a company can make, because companies seldom capture the full value of analytics without capable translators. What are the three components of relational data model? Metadata is data about data characteristics and relationships. As a general rule, a noun in a business rule will translate into an entity in the model, and a verb (active or passive) associating nouns will translate into a relationship among the entities. An entity relationship model, also known as an ERM, helps identify the database's main entities and their relationships. It is described by its factual content and unlike an entity, an object includes information about relationships between the facts within the object, as well as information about its relationships with other objects. database design environment. leverage less expensive commodity processors that have separate RAM and disk. Translating Business Rules into Data Model Components Generally, nouns translate into entities Verbs translate into relationships among entities Relationships are bidirectional Two questions to identify the relationship type: - How many instances of B are related to one instance of A?
