Re[4]: [xml-dev] SQL5

Mukul,

---TML

MG> An XQuery program can
MG> operate on a data model constructed from a RDBMS schema.
(1) XQuery is procedural language like Basic.
If you try to extract whole path from root of XML-tree to specified element,
you get very bulky expression (compare with TML).
Unconvenient. Especially for applied (and busy) specialists.
(2) XPath extracts only specified element instead of whole path,
so it also un-suitable.
(3) ideology of TML is not only whole path, but "functions" for _whole_ tree, e.g.:
continuing and finishing function

aggregates
http://sql50.euro.ru/site/sql50/en/author/tree_eng.htm#aggregates

---DDL, DML

MG> IMHO, you are trying to re-invent the wheel
(3) There are chapters DDL and DML in contents !!
I ask you in which time - tell your opinion about other ideas:
about control of rights for each record
http://sql50.euro.ru/site/sql50/en/author/ddl_eng.htm ,
about extracting a part of sorted records
http://sql50.euro.ru/site/sql50/en/author/dml_eng.htm ,
about request into reference (inquiry) system,
e.g. when you are mistaken in one letter of name of city or something similar
http://sql50.euro.ru/site/sql50/en/author/rough_eng.htm ,
about request, portioned into several databases
http://sql50.euro.ru/site/sql50/en/author/mc_eng.htm .

These proposals for DDL and DML are strongly in way of _traditional_ SQL.
Tell your opinion, please.

I think in other terms: i'm interesting about secretion itself
