D (Visual Studio Team System Glossary)

This glossary defines key terms that are used in the Visual Studio Team System Help.

data collection logger

Software that logs profiling data to a performance data file.

Data Definition Language (DDL)

Statements in SQL that define, instead of manipulate, data (for example, CREATE TABLE, CREATE INDEX, GRANT, and REVOKE).

data generation plan

A file that contains information about a particular database schema and how Data Generator will generate data for it.

Data Manipulation Language (DML)

Statements in SQL that manipulate, instead of define, data (for example, INSERT, UPDATE, DELETE, and SELECT).

database development life cycle

A structured process that is imposed upon the development of the database portion of an application. It is essentially a subset of the software development life cycle that is specific to one or more databases in an application.

database object

A database component (for example, a table, index, trigger, view, key, constraint, default, rule, user-defined data type, or stored procedure in a database). Can also refer to a database.

database project

An offline representation of a database. Each database project contains the scripts that are required to deploy a new database or to update an existing database to a database server. A database project does not contain the data that resides in that database. Database projects are saved as .dbproj files.

database refactoring

The process by which you can modify the names of database objects in such a way that all instances of those names within the database project are modified at the same time. For example, if you rename a column in a database table by using refactoring, you also update all stored procedures, views, indexes, functions, unit tests, and so on that reference the column.

database unit test

A unit test that validates whether a certain aspect of your database is working as you expect.

declarative tests

Ordinary Web tests that are generated by using the Web Test Recorder that is launched when a new Web test is created.

dependent module

A module that contains dependencies from other modules.

development task

An assigned unit of development work usually created to build part of a scenario or quality of service requirement. The development task describes the objective of the developer in the context of an iteration.

differentiating factor

The part of a scenario that determines its uniqueness from other scenarios. The goal of a differentiating factor is to prevent multiple scenarios from being created that describe the same flow through the system.

directive

An instruction in a text template that directs the engine and the host on how to process the template.

disable rule

Choose this option if you do not want to do the analysis for a particular rule, versus suppressing a particular instance of message.

disciplines

Particular specializations that categorize activities and guidance within a process according to a common theme; these may relate to one or to many roles. Key disciplines span across the project lifecycle.

distribution group

A collection of users, computers, contacts, and other groups that is used only for e-mail distribution.

document template

The individual .doc, .dot, .xls, .xlt files, and so forth that we provide with a process to give users a starting point. Some are samples that are edited. Others are templates that must be saved to a new file (from .dot to .doc); these must be in sync with, but separate from, process guidance, both of which roll into the process templates.

domain class

A diagram element that represents a class in a domain-specific language.

domain model

The graphical and in-memory representation (store) of a domain-specific language. You create a domain model by using the Domain-Specific Language Designer Wizard, and you customize a domain model by using the Domain-Specific Language Designer.

domain model element

A diagramming element that defines a domain-specific language. Domain model elements include domain classes, domain relationships, connectors, and shapes.

domain relationship

A diagram element that represents an embedding or reference relationship in a domain-specific language.

domain-specific language

A custom language that targets a problem domain and defines the problem at a high level of abstraction.

DREAD

A ranking of the risk that is associated with a vulnerability or a security requirement. DREAD stands for Damage potential, Reproducibility, Exploitability, Affected users, Discoverability.

duplicate link

A Team Foundation link between two work items that represent the same work item. In practice, this occurs when two people report the same bug.
