Creating Keyspace & Table...

Create Keyspace & Table

Column   : Is a name/value Pair #61
Row      : Is referenced using Primary Key #61
Table    : Similar to Table in RDBMS
Keyspace : Similar to Database in RDBMS

// Create Keyspace
cqlsh> create keyspace firstkeyspace WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};

// Create table

create table firstkeyspace. firsttable( 
   subject text, 
   mark text,
   primary key(subject));

A Column which has the same value for all the rows in a Table can be made as Static Column #60
