Motivation:
All these objects are placed on the DataFrame, but return not a DataFrame, but schema, also we are limited with this schema from DataFrame, but it could not keep, for example, the name of the table and other meta-parameters.
Solution:
Move these bunches of methods to the helper class SqlSchema
and introduce static methods on it, this class could be extendable and also reimplemented for any particular Database
