The relational model has been a dominant database model in the computer industry since the 1980s mainly for storing and retrieving data. However, due to exponential growth of data it is becoming complicated to work with relational model as joining a large number of tables is not working ...
Tree visualizations A tree is a particular type of relational data, consisting of a set of nodes (also called vertices) and a set of edges, where each edge represents a connection of a pair of nodes. In a tree, we can define a unique path (i.e., a set of nodes connected by ...

Database design: ER diagrams are used to model and design relational databases, in terms of logic and business rules (in a logical data model) and in terms of the specific technology to be implemented (in a physical data model.) In software engineering, an ER diagram is often an initial ...
