A specific software component created to fulfill a specific function defined in the
functional and system design documents.
A stage in the software development lifecycle during which a software product is created
from the design specifications and testing is performed on the individual software units
produced. Also referred to as the programming stage.
A software development technique where multiple small software development lifecycles
are used to develop the overall software product in a modular fashion.
A specialized data structure used to facilitate rapid access to individual database records
or groups of records.
Data that has been shaped into a form that is meaningful and useful to humans.
Interrelated components working together to collect, process, store, and disseminate
information to support decision-making, coordination, control, analysis, and/or
visualization in an organization.
A feature of object-oriented programming where a specific class of objects receives the
features of a more general class.
INITIAL DATA LOAD
When a new database application is first brought online, certain sets of data are
preloaded to support operations. In some cases, a large amount of data is transferred
from one or more legacy systems that the new database application is replacing. The
initial data load figure is calculated as the sum of all records in operational and support
data areas on day zero of the applications production lifecycle. This figure is used as a
baseline for estimating development effort, server hardware requirements and network
Synonym for sub query.
The position of the cursor within a block of text.
Also termed desk checking. A quality assurance technique that relies on visual
examination of developed products (usually source code or design documentation) to
detect errors, violation of development standards, and other problems.
A software lifecycle stage that consists of the testing, training, and conversion efforts
necessary to place the developed software application into production.
The degree to which a software component or application prevents unauthorized access
to, or modification of, programs or data.
A whole number, usually limited to a range of -32,000 to +32,000.
A formal connection point defined between two independent applications for the purpose
of data exchange.
A testing technique that evaluates whether software components pass data and control
correctly to one another.
A group of data elements included in two or more tables as part of a Join operation.
