 Schemaless: Nosql Variable state has different instances that have different values that need to be stored inside them.  Common state when most of the instances have the same value so it is easier to reteive. the above is a method in which we can make our RDBMS system more flexible like NoSQL but make them more rigid then the NOSQL. Then in our traditional schema we need the data that fits the schema. But in the predicate one we can handle different types of data and decide how we are going to handle that data. We can use xml for this pupose. To keep a check on xml data we can use xml schema.. but now a days there is relax compact notation. RELAX NG is a simple schema language for XML, based on [ RELAX ] and [ TREX ]. A RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema thus identifies a class of XML documents consisting of those documents that match the pattern. Consider a simple XML represen...
