A database engine is the underlying system that a database uses to function. Many different technologies rely on internal "engines," which are the fundamental building blocks on which they operate.
A process specification is a method used to document, analyze and explain the decision-making logic and formulas used to create output data from process input data. Its objective is to flow down and specify regulatory/engineering requirements and procedures. High-quality, consistent data requires clear and complete process specifications.
A process specification reduces ambiguity, allowing an individual or organization to obtain a precise description of executed tasks and accomplishments and validate system design, including the data dictionary and data flow diagrams.
Process specifications are created for primitive processes and data flow diagram processes of a higher level (minispecs). Process logic is best represented through structured English, decision tables, decision trees or specified formulas or algorithms and is used to communicate engineering requirements and procedures to businesses involved in the creation of a process. Process descriptions may exist on a form or in a computer aided software engineering (CASE) tool repository.
Process specifications are not created for processes requiring physical input or output, processes representing simple data validation or processes with preexisting and prewritten code.
