A software requirements specification (SRS) is a description of a software system to be developed.It is modeled after the business requirements specification.The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
More than 99 percent of DCHA's funding comes from the federal government. In 2012 and 2013, about 77 percent of the agency's total revenues were provided by the U.S. Department of Housing and Urban Development (HUD) for HCVP and an additional 11 percent for DCHA-administered public housing grants.

Historically, MAC was strongly associated with multilevel security (MLS) as a means of protecting classified information of the United States.The Trusted Computer System Evaluation Criteria (TCSEC), the seminal work on the subject and often known as the Orange Book, provided the original definition of MAC as "a means of restricting access to objects based on the sensitivity (as represented by ...
Occasionally, a system as a whole is said to have "discretionary" or "purely discretionary" access control when that system lacks mandatory access control. On the other hand, systems can implement both MAC and DAC simultaneously, where DAC refers to one category of access controls that subjects can transfer among each other, and MAC refers to a ...
The documentation typically describes what is needed by the system user as well as requested properties of inputs and outputs (e.g. of the software system). A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirements Document "PRD" [citation needed].
Business requirements, also known as stakeholder requirements specifications (StRS), describe the characteristics of a proposed system from the viewpoint of the system's end user like a CONOPS. Products, systems, software, and processes are ways of how to deliver, satisfy, or meet business requirements.
