THE DATA STRUCTURES

THE DATA STRUCTURES

1. The data structures are sets of variables that are implemented through programming languages​​.

   • data structures can be considered from two points of view
     • physical point of view.
       • is basically focused on how the information is stored.
     • logical point of view.
       • focuses on the aspect of the relationships between the elements.

2. Operations performed on a data structure.

   • EXPLORE THE STRUCTURE: Make a tour of the structure with the purpose of retrieving stored information.
     • SEARCH: Determines if an item is missing or not in the structure.
       • QUERY INFORMATION: Gets information from one or more elements of the structure.
         • PARTIAL OR TOTAL COPY: Choose a structure wholly or partially with Similar to the original features.
           • TEST: Check if one or more elements meet certain conditions
             • MODIFICATION: Varies partly or wholly content information elements of the structure.
               • DISPOSAL: Deletes elements of the structure.
                 • PRINT: Enter the information contained in the structure.

3. Basic functions for creation, access and destruction of Data Structures.

   • FUNCTION BUILDER: Create the structure, ie, define the characteristics, delimitation, relationships and allocate space Correspondingly, leaving to the user the structure to proceed to place the information.
     • ACCESS TO FUNCTION: Facilitate the arrival of an element belonging to the structure
       • DESTRUCTORA FUNCTION: Return to the system resources assigned to the data structure so that they are available to it.

4. Fuzzy Logic.

   • A fuzzy proposition p is a statement whose truth degree is a real number comprised between 0 and 1, denoted by the expression g (p). The degrees of truth will be expressed in terms absolute through real numbers or in relative terms as percentages:
     • 0 ≤ g(p) ≤ 1 0% ≤ g(p) ≤ 100%.
