This Database Design Document template includes the following chapters, sections and sample text. Package. Like the Talend best practices, I believe we must take our data models and modeling methods seriously. Data Model Documentation. Depending on how you wish to efficiently slice a dataframe, you can choose to model it with either a 1D dense or a ND sparse array. PBG operates on directed multi-relation multigraphs, whose vertices are called entities.Each edge connects a source to a destination entity, which are respectively called its left-and right-hand side (shortened to LHS and RHS).Multiple edges between the same pair of entities are allowed. Type = Reference - this is an attribute reference to another Data model. The Oracle Utilities Data Model is a pre-built, standards-based data model designed and optimized for Oracle data warehousing systems.

Data modeling is a process used to define and analyze data requirements needed to support the business processes within the scope of corresponding information systems in organizations. The data model consists of classes (frames) that describe the different concepts (e.g., reaction, simple entity). Knowledge is captured as instances of these classes (e.g., “glucose transport across the plasma membrane”, “cytosolic ATP”). It enables you to generate entity-relation diagrams.
