Glossary

(IEEE) A record of the execution of a computer program, showing the sequence of instructions executed, the names and values of variables, or both. Types include execution trace, retrospective trace, subroutine trace, symbolic trace, variable trace.

To produce a record as in definition (1).

To establish a relationship between two or more products of the development process; e.g., to establish the relationship between a given requirement and the design element that implements that requirement.

Analyzing constituents present in ppm and ppb concentrations. Trace analysis requires extremely pure reagents made with ultrapure Type I reagent grade water.

(ISO) Ability to trace the history, application or location of that which is under consideration.

(IEEE) The degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor or master-subordinate relationship to one another; e.g., the degree to which the requirements and design of a given software component match.

The degree to which each element in a software development product establishes its reason for existing; e.g., the degree to which each element in a bubble chart references the requirement that it satisfies.

The ability to link a user requirement specification through functional specifications and design specifications to test cases. It should be possible to look at a specification and determine how it was tested, or to look at a test and determine what specifications it challenges.

A prerequisite for trustworthy records, apart from data security. Traceability is the part of the laboratory data system audit trail that holds the evidence of who did what to a record and when.

(IEEE) The tracing of Software Requirements Specifications requirements to system requirements in concept documentation.

The tracing of source code to corresponding design specifications and design specifications to source code. Analyze identified relationships for correctness, consistency, completeness, and accuracy.

The tracing of software design descriptions to software requirements specifications and software requirements specifications to software design descriptions.

(IEEE) A matrix that records the relationship between two or more products; e.g., a matrix that records the relationship between the requirements and the design of a given software component.

Substance or microorganism used to measure the quantitative development of soiling. ISO 14698-3.NOTE 1: In order to measure the efficiency of a process, the microorganisms which have developed within soiling, with or without formation of a biofilm, may be used as a tracer.NOTE 2: Activities such as cleaning, rinsing, and biochemical or mechanical action eliminate soiling and biofilm by removal. The aim of disinfection is, by definition, to destroy or inactivate microorganisms. Consequently, it may be desirable to measure, in the overall efficiency of a process, that which may be attributed to the eliminative action, in order to distinguish this from the effect of the killing (destructive) action. To this end, one or more additional tracers may be chosen, whether naturally present in the soiling or to be added to it, that ere not liable to be destroyed.

A radioactively labeled nucleic acid component included in a reassociation reaction in amounts too small to influence the progress of reaction.

Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts

The HIPAA Privacy Rule gives individuals the right to request an accounting of disclosures of protected health information over the previous six years. If an individual authorizes uses or disclosures for research, the disclosures do not need to be tracked, but disclosures must be tracked if the researcher receives an IRB-approved waiver of authorization. The accounting of disclosures generally must include: the date of the disclosure, the name of the entity or person (and address if known) who received the protected health information, a brief description of the information disclosed, and a brief statement of the purpose of the disclosure. An alternative tracking option is available for research involving 50 or more people.

Designates an assembly of connected equipment, which as a unit, serves to process and deliver a product. A train is not an architectural entity, and does not equate to a room or processing space. Trains can and often do transcend several "Suites" in their implementation.

In a database management system, a unit of processing activity that accomplishes a specific purpose such as a retrieval, an update, a modification, or a deletion of one or more data elements of a storage structure.

An exchange between and end user and an interactive system.

(ANSI) A command, message, or input record that explicitly or implicitly calls for a processing action, such as updating a file.

A structured software design technique, deriving the structure of a system from analyzing the transactions that the system is required to process.

A model of the structure of the system's [program's] behavior, i.e., functionality.

(IEEE) A matrix that identifies possible requests for database access and relates each request to information categories or elements in the database.
