Elementary data organisation

  1. 1. Elementary Data Organization
  2. 2. Outline <ul><li>Data, Entity and Information </li></ul><ul><li>Primitive data types </li></ul><ul><li>Non primitive data Types </li></ul><ul><li>Data  structure </li></ul><ul><ul><li>Definition </li></ul></ul><ul><ul><li>Classification </li></ul></ul><ul><li>Data structure operations. </li></ul>
  3. 3. Data, Entity and Information <ul><li>Data represents a single value or a set of values assigned to entities. Data item refers a single or group of values with in the data </li></ul><ul><li>An entity is a thing that has some properties which can take values. </li></ul><ul><li>Processed or meaning full data is called information. This is used for taking some action. </li></ul>
  4. 4. Primitive data types <ul><li>These are the data structures which are directly supported by the machine.i.e.Any operation can be performed in these data items. </li></ul><ul><li>The different primitive data types are </li></ul><ul><ul><li>Integer </li></ul></ul><ul><ul><li>Float </li></ul></ul><ul><ul><li>Double </li></ul></ul><ul><ul><li>Character </li></ul></ul><ul><ul><li>boolean </li></ul></ul>
  5. 5. Non Primitive data types <ul><li>These Datastructures do not allow any specific instructions to be performed on the Data items directly. </li></ul><ul><li>The different non primitive data types are </li></ul><ul><ul><li>Arrays </li></ul></ul><ul><ul><li>Structures </li></ul></ul><ul><ul><li>Unions </li></ul></ul><ul><ul><li>Class etc. </li></ul></ul>
  6. 6. Data  structure <ul><li>A data structure is an arrangement of data in a computer's memory or even disk storage. An example of several common data structures are arrays, linked lists, queues, stacks, binary trees, and hash tables. </li></ul><ul><li>Algorithms , on the other hand, are used to manipulate the data contained in these data structures as in searching and sorting. Many algorithms apply directly to a specific data structures. </li></ul>
  7. 7. Data  structure <ul><li>When working with certain data structures you need to know how to insert new data, search for a specified item, and deleting a specific item. </li></ul><ul><li>Commonly used algorithms include are useful for: </li></ul><ul><ul><li>Searching for a particular data item (or record). </li></ul></ul><ul><ul><li>Sorting the data. There are many ways to sort data. Simple sorting, Advanced sorting </li></ul></ul><ul><ul><li>Iterating through all the items in a data structure. (Visiting each item in turn so as to display it or perform some other action on these items) </li></ul></ul>
  8. 9. Classification <ul><li>There are two types of data structure. They are </li></ul><ul><ul><li>Linear Datastructures </li></ul></ul><ul><ul><li>Non-Linear Datastructures </li></ul></ul>
  9. 10. Linear Data structures <ul><li>This Data Structures involve arranging the elements in Linear fashion. </li></ul><ul><li>Eg. </li></ul><ul><ul><li>Stacks </li></ul></ul><ul><ul><li>Queue </li></ul></ul><ul><ul><li>Lists </li></ul></ul>
  10. 11. Non-Linear Data structures <ul><li>This Data structures involve representing the elements in Hierarchical order. </li></ul><ul><li>Eg: </li></ul><ul><ul><li>Trees </li></ul></ul><ul><ul><li>Graphs </li></ul></ul>
  11. 12. Data structure operations <ul><li>Operation means processing the data in the data structure. The following are some important operations. </li></ul><ul><ul><li>Traversing </li></ul></ul><ul><ul><li>Searching </li></ul></ul><ul><ul><li>Inserting </li></ul></ul><ul><ul><li>Deleting </li></ul></ul><ul><ul><li>Sorting </li></ul></ul><ul><ul><li>Merging </li></ul></ul>
  12. 13. operations <ul><li>Traversing </li></ul><ul><li>To visit or process each data exactly once in the data structure </li></ul><ul><li>Searching </li></ul><ul><li>To search for a particular value in the data structure for the given key value. </li></ul><ul><li>Inserting </li></ul><ul><li>To add a new value to the data structure </li></ul>
  13. 14. operations <ul><li>Deleting </li></ul><ul><li>To remove a value from the data structure </li></ul><ul><li>Sorting </li></ul><ul><li>To arrange the values in the data structure in a particular order. </li></ul><ul><li>Merging </li></ul><ul><li>To join two same type of data structure values </li></ul>
  14. 15. The End <ul><li>THANK YOU </li></ul>
