Database Design

Business Rule

A brief and precise narrative of a policy, procedure, or principle within a specific organization's environment.

Database

A carefully designed and constructed repository of facts that is a part of a larger whole known as an information system.

Conceptual Design

A stage that uses data modeling to create an abstract database structure that represents real-world objects in the most realistic way possible.

Virtualization

A technique that creates logical representations of computing resources that are independent of the underlying physical computing resources.

Module

An information system component aht handles a specific business function, such as inventory, orders, or payroll.

Database Life Cycle Database Initial Study Phase

Systems Development Life Cycle's Analysis Phase

Discovery of user requirements, existing system evaluation, and logical system design.

Distributed Database Design

In the context of the database design process, the conceptual design step that defines the fragmentation and allocation strategy.

Data Analysis and Requirements

In the context of the database design process, the conceptual design step that determines end-user views, outputs, and transaction-processing requirements.

Data Model Verification

In the context of the database design process, the conceptual design step that identifies ER modules and validates insert, update, and delete rules.
