    HTML 4.01 Specification since PDF 1.5; HTML 2.0 since 1.2 Forms Data Format (FDF) based on PDF, uses the same syntax and has essentially the same file structure, but is much simpler than PDF since the body of an FDF document consists of only one required object. Forms Data Format is defined in the PDF specification (since PDF 1.2).

  3. Design structure matrix - Wikipedia

    en.wikipedia.org/wiki/Design_structure_matrix

    The design structure matrix (DSM; also referred to as dependency structure matrix, dependency structure method, dependency source matrix, problem solving matrix (PSM), incidence matrix, N2 matrix, interaction matrix, dependency map or design precedence matrix) is a simple, compact and visual representation of a system or project in the form of ...

  4. Data structure - Wikipedia

    en.wikipedia.org/wiki/Data_structure

    A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.

  5. von Neumann architecture - Wikipedia

    en.wikipedia.org/wiki/Von_Neumann_architecture

    The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [1] The document describes a design architecture for an electronic digital computer with these components: The ...

  6. Unified Modeling Language - Wikipedia

    en.wikipedia.org/wiki/Unified_Modeling_Language

    The unified modeling language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. [ 1 ] UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure diagrams.

  7. STL (file format) - Wikipedia

    en.wikipedia.org/wiki/STL_(file_format)

    STL format is not the most memory- and computationally efficient method for transferring this data, but STL is often used to import the triangulated geometry into the CAM system. The format is commonly available, so the CAM system will use it. In order to use the data, the CAM system may have to reconstruct the connectivity.

  8. Software design pattern - Wikipedia

    en.wikipedia.org/wiki/Software_design_pattern

    Software design pattern. In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code. Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase ...

  9. Structured systems analysis and design method - Wikipedia

    en.wikipedia.org/wiki/Structured_systems...

    Structured systems analysis and design method. Structured systems analysis and design method (SSADM) is a systems approach to the analysis and design of information systems. SSADM was produced for the Central Computer and Telecommunications Agency, a UK government office concerned with the use of technology in government, from 1980 onwards.
