SQL 5.8.0

English Russian

SQL5 allow by XPath to create foreign key (FK) between rational and xml, between xml and xml; to copy rational data (tree's model is over rational model) into xml and xml-data into records of tables by XTree; to select, update, delete xml in fields of tables; to create predicates, permissions, triggers for xml-data. It's shown, that usage of XML and HTTP instead of formats and protocols, applied by separate company-manufacturer of DBMS, gives great advantage for end user, automating own activity without programmers. SQL5 allow to refer into several databases in one request, using nickname of database as prefix of table name and system table of nicknames; replication by this technology is possible. To specify right of access for each record, and to make some records invisibile for certain users. To use in-exact names, differing by one-two letters or permutation of words, in request. To create timer, to send next small portion of sorted data to client by usual sql-requests, and many others.
