5 HBase Vs. RDBMS Top Functional Differences

Here're the differences between RDBMS and HBase. HBase in the Big data context has a lot of benefits over RDBMS. The listed differences below make it understandable why HBASE is popular in Hadoop (or Bigdata) platform.  5 HBase Vs. RDBMS Top Functional Differences Here're the differences unlock now. 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 follows Codd's 12 rules with fixed schemas and row-oriented manner of database and also follows ACID properties. HBase follows BASE properties and implements 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 provides the solution with MyS

Linux Relative Vs. Absolute Path Top Differences

Here's the difference between the relative and absolute paths in Linux. Many a time, the programmer needs to trade in these paths. Here're simple ideas on how you can differentiate.

Linux directory pathnames are two types. Those are absolute and relative. I have explained the differences between these two with simple examples.

Absolute Vs. Relative Path in Linux

Below are the differences between these two.

1. Absolute pathname

  • An example is /usr/lib, which is an exact directory in the directory tree. 
  • Think of the absolute pathname as being the complete mailing address for a package that the postal service will deliver to your next-door neighbor.

2. Relative pathname

  • This path tells from the beginning.
  • An example is cups, which represent 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. 

3. How to go back to the home directory

If I type cd cups in /usr/lib, the current directory changes to /usr/lib/cups. If type the same command in /home/edulaney, the shell tries to change the current directory to /home/edulaney/cups.

If you type cd, without any arguments, it will go to the home directory.
