UML Class Diagram. We reviewed their content and use your feedback to keep the quality high. A data model can, however, portray the data parameters that . In translating business rules into data model components, a noun is translated as an entity, a verb (active or passive) associated with the nouns translates the relationship between the entities, and an adjective translates as an attribute for the associated noun(s). Standardization is important to users and designers because it allows them to shift from one commercial application to another with little trouble when they operate at the logical level. They support very large amounts of sparse data. Companies are using social media to gain information and competitive advantages and huge volume of data requires data analytics to make the best of this phenomenon. Each relation (table) is conceptually represented as two-dimensional structure of intersecting rows and columns. What is a table, and what role does it play in the relational model? Velocity refers to the speed with which data grows and the need to process these data quickly in order to generate information and insight.
