Efficient data management is one of the biggest challenges for companies dealing with large volume of data. This is where data mining comes into picture. This is the process of extracting patterns out of raw data and giving an easy to understand and execute data interface. However, when it comes to solving extremely large queries over cloud network using extensive databases, even the process of data mining can be too time consuming. MapReduce is a frame work developed by Google to facilitate various function required for managing large volume of data.
MapReduce frame work works on two basic functions, Ma p and Reduce. Whenever the master node in a cloud network is assigned a data query for execution, the Map function comes into play. It collects the query assigned to the master node and breaks it down to a number of smaller sub-problems. The sub-problems are then given to different nodes in the network. Once all the sub-problems are executes by the nodes in the network, the reduced function starts its work. It collects the solutions of the sub-problems from the nodes and delivers them back to the master node. The Master node combines the solution of the sub-problem to derive the output of the problem it was assigned.
This process of dividing the work and distributing it to all the nodes in a network greatly reduces the time required to execute a data processing request. Furthermore, MapReduce frame work has the capability of diagnosing any non responsive or dead nodes on the network. Under any scenario wherein any of the nodes on the network fails to deliver the expected output, its sub-problem is assigned to a different node in the network, and the faulty node is reported to the master node.
Today, IT solutions providers are offering enhanced frameworks to further improve the efficiency of a company’s data system. If you are planning to get a MapReduce based framework for you company’s needs of managing data, you can easily find a reputed company offering a robust MapReduce framework to enhance the efficiency of your data management system.
