Which type of relationship is logically supported but can't be represented by Visio or any database modeling process?

The type of relationship that is logically supported but often can't be represented in Visio or traditional database modeling processes is a many-to-many relationship with attributes. While many-to-many relationships can be depicted using junction tables, the additional attributes associated with the relationship itself are typically not easily represented in standard diagramming tools. This complexity often requires a more nuanced approach, such as using additional entities or notes to capture the attributes effectively.


What is difference between System Analysis and Unified Modeling Language?

System Analysis is the process of studying a system's components and their interactions to understand its functionality and identify areas for improvement or redesign. Unified Modeling Language (UML), on the other hand, is a standardized visual language used to create models of software systems, facilitating the representation of system components, behaviors, and interactions. While system analysis focuses on understanding and evaluating systems, UML provides the tools to visually represent that understanding. In essence, UML can be a part of the system analysis process, serving as a method for documenting findings.


What are the types of relationships used in Database modeling?

In database modeling, the primary types of relationships are one-to-one, one-to-many, and many-to-many. A one-to-one relationship means a single record in one table is linked to a single record in another table. A one-to-many relationship allows a single record in one table to be associated with multiple records in another table. Lastly, a many-to-many relationship occurs when multiple records in one table relate to multiple records in another, often necessitating a junction table to manage the associations.


Difference between an entity class and an entity instance?

"An entity is a person, place, event, or thing about which data is collected...An instance is an occurence of an entity." - Systems Analysis & Design (4th) - DennisAn example of this would be STUDENT as the entity while JACK SMITH is an instance of that entity.If an entity is an individual "person, place, event, or thing about which data is collected", then an entity is an instance. Linguistically, entity is just another word for a single thing ("The existence of a thing as contrasted with its attributes.", Merriam-Webster's On-line Dictionary). Entities that have the same attributes are grouped in what are best called entity classes (it doesn't make sense to refer to a collection of entities as an entity). Entity and entity class are data modeling terms. The corresponding object modeling terms are object and class, albeit that a class typically has operations, which are foreign to an entity class.
