Thanks for the question, ritesh05! I searched on Google a bit and found out this site: https://hbase.apache.org/. Looks like it's an Apache sub-site. Looks to me that it's all about accessing the 'big-data' (latest technology buzz-word) in reliable, scalable, distributed computing (say Hadoop) environment. Of course, I do not know the technicalities of the HBase; maybe someone more informed can inform us about it.
Google's BigTable is nothing but a database system built on Google File System. So basically, it is a technology built for Google and by Google.ritesh05Recently heard about this technology even fb is using it for it messages. And what is google's big table.
Though it shouldn't go without noticing that we can access it through 'Google App Engine'.
