    The situation, task, action, result (STAR) format is a technique [1] used by interviewers to gather all the relevant information about a specific capability that the job requires. [ citation needed ] Situation : The interviewer wants you to present a recent challenging situation in which you found yourself.

  3. GRASP (object-oriented design) - Wikipedia

    en.wikipedia.org/wiki/GRASP_(object-oriented_design)

    The indirection pattern supports low coupling and reuses potential between two elements by assigning the responsibility of mediation between them to an intermediate object. An example of this is the introduction of a controller component for mediation between data (model) and its representation (view) in the model-view-controller pattern.

  4. Star schema - Wikipedia

    en.wikipedia.org/wiki/Star_schema

    The star schema is an important special case of the snowflake schema, and is more effective for handling simpler queries. [2] The star schema gets its name from the physical model's [3] resemblance to a star shape with a fact table at its center and the dimension tables surrounding it representing the star's points.

    In Unicode, the "Eight Spoked Asterisk" symbol is U+2733.; The spikes are specially visible around Jupiter's moon Europa (on the left) in this NIRCam image.. The 8-pointed diffraction spikes of the star images from the James Webb Space Telescope are due to the diffraction caused by the hexagonal shape of the mirror sections and the struts holding the secondary mirror.

  6. Optical flow - Wikipedia

    en.wikipedia.org/wiki/Optical_flow

    Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. [ 1 ] [ 2 ] Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image.

  7. Software design description - Wikipedia

    en.wikipedia.org/wiki/Software_Design_Description

    A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.

    Using a "Dictionary Definition Language" file, itself a STAR File, STAR sub-formats can be defined for particular use cases. One notable STAR-based [1] format is the Crystallographic Information File format. The "STAR FILE" name is a registered trade mark of the International Union of Crystallography. [2]

  9. Diffraction spike - Wikipedia

    en.wikipedia.org/wiki/Diffraction_spike

    Effect of a triangular star filter. A cross screen filter, also known as a star filter, creates a star pattern using a very fine diffraction grating embedded in the filter, or sometimes by the use of prisms in the filter. The number of stars varies by the construction of the filter, as does the number of points each star has.
