Hi Welcome to Programming Hadoop
Hi,
Here I want to explain brief about "Hadoop".
Hadoop is a Opensource product developed by Apache. to handle BigData.
Generelly, DataWareHouses and BI(Business Intelligence) systems, are able to work
on structured data.... but not on unstructured data.
example for unstructured data is large text files, documents, log files(database log or weblog),
web crawling data... for these things definetely the storage should be in file systems.
That too... The BI tools and DW tools can not process huge volumes of data...if data is petabytes,
zettabytes or yottabytes....Where hadoop is able to process both structured and unstructured format
of data in big sizes.
to store this, powerful filesystem is provided by Hadoop called HDFS.
To process this data in faster manner, Hadoop is providing some echo systems as follows.
MapReduce,
Pig,
Hive,
Hbase,
flume,
Sqoop etc.
and other nosql databases are also used such as
MongoDb,
DynamoDb,
CouchDb etc.
for more details please send me reply...
