HBASE Vs. RDBMS Top Differences You can Unlock Now

HBASE in the Big data context has a lot of benefits over RDBMS. The listed differences below make you understandable why HBASE is popular in Hadoop (or Bigdata) platform. Let us check one by one quickly. HBASE Vs. RDBMS Differences Random Accessing HBase handles a large amount of data that is store in a distributed manner in the column-oriented format while RDBMS is systematic storage of a database that cannot support a random manner for accessing the database. Database Rules RDBMS strictly follow Codd's 12 rules with fixed schemas and row-oriented manner of database and also follow ACID properties. HBase follows BASE properties and implement complex queries. Secondary indexes, complex inner and outer joins, count, sum, sort, group, and data of page and table can easily be accessible by RDBMS. Storage From small to medium storage application there is the use of RDBMS that provide the solution with MySQL and PostgreSQL whose size increase with concurrency and performance.  Codd'

Linux Relative Vs. Absolute Path Top Differences

Linux directories are helpful to store files. Many a time, the programmer would trade in directory paths. The paths are two types - absolute and relative. I have shared simple ideas to remember the differences between these two. Linux Absolute Vs. Relative Path in Linux Below are the differences between these two. 1.

Relative pathname An example is cups, which represents the cups subdirectory of the current directory, whatever that may be.  Think of the relative directory name as giving the postal carrier directions from your house to the one next door so that the carrier can deliver the package. Useful differences, how to differentiate the differences between absolute and real paths. How to go back to the home directory If I type  cd cups  in
