I ask you to help in development (or critic).

SQL4 consist of DDL, DML and TML (Tree Manipulation Language).
TML4 is new advanced query language, which processes trees and counts in database,
put them into it, and get them from it (tree's model of data is over rational model).

SQL 4.0.4 is project of novations:
* DDL4 installs right of access to each record
* TML considers records of tables, bound by foreign key, as elements of tree.
It's un-important, next element of tree is
parental table or branch table - it's necessary only foreign key between two tables
Elements of tree can be a set and a list
* TML uses mask for specification necessary sub-trees,
inserts and deletes elements of sets, of lists, and also whole sub-trees,
changes values of field in any nodes of tree
* DBMS transform got XML into records of tables;
transform records of tables, bound by foreign keys, into XML
* Way to solve collision is specified, when one record is bound
with several records of other tables
* Communication with external world occurs by HTTP,
that at least one of possible client of DBMS
could communicate with it without middle-ware.
Client gets picture from database by its URL and
separately from XML-data
