  2. IDEF1X - Wikipedia

    en.wikipedia.org/wiki/IDEF1X

    Phase two – relationship definition The objective of the relationship definition phase is to identify and define the basic relationships between entities. At this stage of modeling, some relationships may be non-specific and will require additional refinement in subsequent phases. The primary outputs from phase two are: Relationship matrix

  3. Pushdown automaton - Wikipedia

    en.wikipedia.org/wiki/Pushdown_automaton

    In the theory of computation, a branch of theoretical computer science, a pushdown automaton (PDA) is a type of automaton that employs a stack. Pushdown automata are used in theories about what can be computed by machines.

  4. Deterministic pushdown automaton - Wikipedia

    en.wikipedia.org/wiki/Deterministic_pushdown...

    As an example they are (effectively) closed under complementation, but not closed under union. To prove that the complement of a language accepted by a deterministic PDA is also accepted by a deterministic PDA is tricky because one has to avoid infinite computations and correctly handle transitions that manipulate the stack without reading ...

  5. State-transition table - Wikipedia

    en.wikipedia.org/wiki/State-transition_table

    In automata theory and sequential logic, a state-transition table is a table showing what state (or states in the case of a nondeterministic finite automaton) a finite-state machine will move to, based on the current state and other inputs.

  6. Decision matrix - Wikipedia

    en.wikipedia.org/wiki/Decision_Matrix

    A decision matrix is a list of values in rows and columns that allows an analyst to systematically identify, analyze, and rate the performance of relationships between sets of values and information. Elements of a decision matrix show decisions based on certain decision criteria.

  7. Cardinality (data modeling) - Wikipedia

    en.wikipedia.org/wiki/Cardinality_(data_modeling)

    The entity–relationship model proposes a technique that produces entity–relationship diagrams (ERDs), which can be employed to capture information about data model entity types, relationships and cardinality. A Crow's foot shows a one-to-many relationship. Alternatively a single line represents a one-to-one relationship. [4]

  8. Link analysis - Wikipedia

    en.wikipedia.org/wiki/Link_analysis

    Link analysis focuses on analysis of relationships among nodes through visualization methods (network charts, association matrix). Here is an example of the relationships that may be mapped for crime investigations: [3]

  9. Responsibility assignment matrix - Wikipedia

    en.wikipedia.org/wiki/Responsibility_assignment...

    In business and project management, a responsibility assignment matrix [1] (RAM), also known as RACI matrix [2] (/ ˈ r eɪ s i /; responsible, accountable, consulted, and informed) [3] [4] or linear responsibility chart [5] (LRC), is a model that describes the participation by various roles in completing tasks or deliverables [4] for a project or business process.
