Using simple arrays

• Similar data can handled more efficiently when
  stored and manipulated as a collection.
• Collections are two types Generic collections
  and non-generic collections.
•  System.Collections is a very important namespace

  specifying bracketed values for each row.
• 2-dimensional array is the easiest form of the

  System.Collections
• Generic namespace and it provides the methods and
  properties like other Collection classes such as
  add, insert, remove, search etc.
• Syntax Listltintgt iList new Listltintgt()
• Adding new values to the arrays using list
  follows
• Syntax iList.Add(2)

Managing unordered data with dictionaries

• Dictionaries in C sharp is like a hash table in
  some applications.
•  It's an unordered collection of data. 
• Each item in the collection has a key and a
  value.
• Data dictionary is one tool organizations can use
  to help ensure data accuracy.
