Database design is the process of specifying the logical and/or physical parts of a database. The goal of database design is to make a representation of some \"universe of discourse\" - the types of facts, business rules and other requirements that the database is intended to model
Questions : 1 :: What Is Database Design?
Database design is the process of producing a detailed data model of database. This data model contains all the needed logical and physical design choices and physical storage parameters needed to...View answers
Questions : 2 :: What Is The Logical Design Of A Database?
The process of logical design involves arranging data into a series of logical relationships called entities and attributes. An entity represents a chunk of information. In relational databases, an...View answers
Questions : 3 :: What Is The Structure Of A Database?
Instead of having all the data in a list with a random order, a database provides a structure to organize the data. One of the most common data structures is a database table. A database table...View answers
Questions : 4 :: What Is A Logical Data Model?
A logical data model or logical schema is a data model of a specific problem domain expressed independently of a particular database management product or storage technology (physical data model) but...View answers
Questions : 5 :: What Is A Conceptual Data Model?
A conceptual schema is a high-level description of a business's informational needs. It typically includes only the main concepts and the main relationships among them. ... The conceptual model is...View answers
Questions : 6 :: What Is The Physical Data Model?
A physical database model shows all table structures, including column name, column data type, column constraints, primary key, foreign key, and relationships between tables. Features of a physical...View answers
Questions : 7 :: What Is The Conceptual Design Of A Database?
This phase is called conceptual design. The result of this phase is an Entity-Relationship (ER) diagram or UML class diagram. It is a high-level data model of the specific application area. It...View answers
Questions : 8 :: What Is A Conceptual Model For Research?
A conceptual model is a representation of a system, made of the composition of concepts which are used to help people know, understand, or simulate a subject the model represents. Some models are...View answers
Questions : 9 :: What Is The Framework Of A Research?
Theories are formulated to explain, predict, and understand phenomena and, in many cases, to challenge and extend existing knowledge within the limits of critical bounding assumptions. The...View answers
Questions : 10 :: What Is The Conceptual Framework?
