A database is a collection of data, typically describing the activities of one or more related organizations. Entities such as students, faculty, courses, and classrooms. Relationships between entities, such as students' enrollment in courses, faculty teaching courses, and the use of rooms for courses.
A database management system, or DBMS, is software designed to assist in maintaining and utilizing large collections of data. Data Analysis: How can a user answer questions about the enterprise by posing queries over the data in the DBMS? A data model is a collection of high-level data description constructs that hide many low-level storage details. A widely used semantic data model called the entity-relationship (ER) model allows us to pictorially denote entities and the relationships among them.
A description of data in terms of a data model is called a schema. The conceptual schema (sometimes called the logical schema) describes the stored data in terms of the data model of the DBMS. The physical schema specifies additional storage details. The Entity Relationships (ER) data 'model allows us to describe the data involved in a real-world enterprise in terms of objects and their relationships and is widely used to (levelop an initial databa.'3e design. The database design process can be divided into six steps. The ER model is most relevant to the first three steps. 1. 2. 3. 4. 5. 6.
unified modeling language (UML) approach 1. Business Modeling: 2. System Modeling: 3. Conceptual Database Modeling: 4. Physical Database Modeling: 5. Hardware System Modeling: Activity diagrams 8hmv the flow of actions in a business process. Statechart diagrams describe dynamic interactions between system objects. Class diagrams are similar to ER diagrams, although they are more general in that they are intended to model application entities (intuitively, important program components) and their logical relationships relationships in addition to data entities and their relationships.
These pieces of information are called data. A database is an organized collection of information. To manage databases, you need database management systems (DBMS). A DBMS is a program that stores, retrieves, and modifies data in the database on request.
A relational database is a collection of relations or twodimensional tables.
