Physical independence is a condition in which the physical model can be changed without affecting the internal model. Explain how the entity relationship (ER) model helped produce a more structured relational database design environment. business rules set the stage for the proper identification of entities attributes and relationships and constants. On the other hand, it introduced a gap between the end users and their data, which then influenced the development of many types of computer technologies, system designs, and uses of many technologies and techniques. Weve seen companies hatch ambitious plans to apply analytics in dozens of situationsonly to pull back because they employ too few people who can deliver solutions. 2. These business rules are then translated into data structures to formulate a concrete database design. 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. The name of the relationship is usually an active or passive verb.Figure 2.3. Department managers Tables are especially useful from the modeling and implementation perspecectives. The formal charges on the O\mathrm{O}O atoms in the ion [ONO]+[\mathrm{ONO}]^{+}[ONO]+is 1. What is connectivity?

Our experience suggests that translators spend six to twelve months in training. Graphically represents the database's entities, attributes in those entities, and relationships among entities. the task of creating a conceptual data model that could be implemented in any DBMS. The output of the conceptual design process. Therefore, database designers label the relationship "PAINTER paints PAINTING" as 1:M. Note that entity names are often capitalized as a convention, so they are easily identified. 7. While translators can acquire some of the requisite knowledge for the job through coursework, they make the most impact once they have developed practical skills through on-the-job experience. The translator first helps define a business problem and translates it to data scientists in technical terms. A relational diagram is a visual representation of the relational database's entities, the attributes within those entities, and the relationships between those entities. Name, Surname, ID_CARD_NUMBER, address etc. acts as the interface between the user application. Analysts define these constraints during the data design stage, rather than during application design.
