Introduction to Filter in DataSet

When you are using Dataset and your dataset is full of employee list. Sometime you want to filter a specific records based on employeeid and department code, here you can use DataSet select command. DataSet is disconnected from the data source, it is often impractical and resource-intensive to re-execute SQL commands to perform these actions.

Code Snippet
  1. DataSet dsQueue = GetMyEmployeeData();//return employees
  2.         
  3.         DataRow[] row = dsQueue.Tables[0].Select("EmployeeID = " +
  4.             emmpIdVariable + " And Department ='" + deptNameVariable + "'");
  5.  
  6.         if (row.Length > 0)
  7.         {
  8.             //Matching rows found
  9.         }
  10.         else
  11.         {

Hadoop Introduction


Hadoop (Apache Hadoop) is a world's best data management system to store and process the largest data( in distributed environment (Cluster), specially for unstructured data or Big Data for e.g. Data from social media such, Govt Data, Weather forecasting etc. Hadoop is good for storing large or Petabytes of data and it is not designed for Real time or low latency queries. Since 1990 Storage capacity has grown exponentially but read speed is not up to the mark, so Hadoop is the solution. In Hadoop 100, 200 drives are working at the same time and can read 1 TB of data in just 2 or less than 2 minutes.  Its a Open system and used by many big clients for e.g. Facebook, Linked In, Google, Yahoo & Indian Govt to process their AADHAR card(A unique Identity for their citizens).
