Re: SQL5 budget

Hi, Pgsql-hackers.

Full list of changes of two related projects (SQL5 & HTML6) at current moment
(not reflected in documentation yet).

===terms
 master table is table, to primary key of which this (slave) table refers (terms "master" and "slave" are used only for
MTD).if master table is not represented in the same html-document, where slave is (created by "select '<table
name="A">'"),then new separate browser window will appear, and content of master table will shown in it. master and
slavetable must be bound by only one foreing key in database. 
 communication - must be implemented via SQL5 over TCP (look at slides #27-28 of http://sql50.euro.ru/sql5.16.4.pdf)
withoutclosing TCP-connection after obtaining XML-document 
 because saments are saved in database, but baments are not (we don't need to save temporary service information),
insteadof sament 
<_ name= event= arg= > the following bament must be sent
<?mtd name= event= arg= /?>

<table name="M">
<table name="S"> with CSS
table[name=M] { online:yes; portion:50; visual:20 }
table[name=S] { online:yes; portion:40; visual:10; master:M }

table[name=S] { online:yes; portion:40; visual:10; master:M/§s3 N/§s4 P/§s5 } where §s3, §s4, §s5 are fields of table
"S"

 instead of sament
<_ name= event= arg= > the following bament must be sent
<?mtd name= event= arg= /?>  as well as instead of
<_ name= event= arg= >
<a a1= a2= a3=> the following construction must be sent

table [name=A] { §a2: B }                            /* 'portion', 'visual' are inherited */
 in addition to mentioned, statement
table [name=A] { §a2: B C } means, that "C" is master table for "B", "B" is master table for "§a2", and that browser
representscontent "C" before content "B" to choose sub-set of "B" 

 in addition to mentioned in paper, each 1-st click on column header (e.g. concerning to xml-attribute @a2) sends
bament
<?mtd name= event=asc  arg=a2/?>  each 2-nd click sends bament
<?mtd name= event=dsc  arg=a2/?>  each 3-rd click sends bament
<?mtd name= event=none arg=a2/?>

 in addition to mentioned in paper, master table rise appearance of new separete browser window and displaying content
ofslave table in it, if  *) additional virtual column is specified in CSS for master table    (slave field is specified
too,if several fields of slave table refer to one master table) 
table[name=M] §m20::after { slave:S/§s5 } *) user make double-click on this virtual column Relation "master-slave" is
servedby the same saments, as relation "slave-master"; but refering key will be specified

 in addition to mentioned in papers, tree as master element for table is possible
ul   [name=A] { online:yes }
table[name=S] { online:yes; portion:40; visual:10; master:A } and browser sends at user actions
<?mtd name=S event= arg= >
<li id=1>
</?mtd> it's supposed, that foreign key of database table "S" refers to primary key of database table "A"
 database table, corresponding to HTML-tree, consists of only two fields - of primary key (extracted as @id), and of
anyother field with any name (extracted as content of element LI) 

===other HTML6 additions
 pressing browser botton "back" not only display previos XML-document, but also sends bament
<?back/?> (which rollback transaction in DBMS to previos 'select ...')

--
 bottons to append and remove table row must be implemented in menu of browser window (implementation in way of
WebForms2is optional) 

--  botton to commit transaction must be implemented in menu of browser window, pressing on which will send
<?commit/?>

--
 property 'save' means, that at pressing ^S, html/xml-document will be saved with entered values
input { save:yes }

in regard to
http://sql50.euro.ru/sql5.16.4.pdf (slide #31,etc)
 in addition to mentioned in pdf-document, statement
SELECT ... COMMENTING. extracts additional record from table as first xml-element, attributes of which contain
comments,specified for each field earlier by statement 
COMMENT tab/@fld BY "column title"; this first xml-element contains additional service xml-attribute '_=comment'.
usuallycomments are specified for html-tables, instead of html-trees

 in addition to mentioned in pdf-document, obtaining single xml-element (instead of xml-tree) with primary key (PK) for
DBMStable (specified in some xml-attribute) means the following: 
*) if this PK is already in DBMS table, then DBMS *updates* fields of record with this PK
*) if this PK is not in table (this usually means, that record with this PK was already deleted), then DBMS *inserts*
thisxml-element under new PK (obtained from sequence for this PK), i.e. PK will be changed during insertion.

http://html60.euro.ru/site/html60/en/author/looker_eng.htm (for "select '<table name="A">'", i.e. extracting HTML )

http://html60.euro.ru/site/html60/en/author/quest_eng.htm#webforms_data (<data id="records">...</data>)
 each 'select ...' extracts data into LAN or WAN (instead of 'insert ... select ...' and 'select ... into ...', coping
datainto internal DBMS table). each 'select ... union ... select ...' interpreted as single extraction of xml into LAN
orWAN. 
 in addition to mentioned in pdf-document, each extraction of data into LAN or WAN is automatically:
*) anticipated by content of field 'beginning' of system table 'SysXmlFormatting'
*) ended by content of field 'end' of system table 'SysXmlFormatting' and
*) by bament <?new/?> (to inform client, e.g. browser, about end of parcel [sent by MTD]  and end of document [sent by
"select* from A"] ) 
P.S.
Other field of system table 'SysXmlFormatting' is URL
(which specifies browser URL; 'null' means all URL and is applied,
only if 'SysXmlFormatting' does not contain record with exact URL).

in regard to
http://sql50.euro.ru/sql5.16.4.pdf (slide #173)
 authentification (obtaining username and password, slide #173) must be implemented by baments (look at slides #26-27)
andis described nowhere.

http://sql50.euro.ru/site/sql50/en/author/mtd_eng.htm
http://html60.euro.ru/site/html60/en/author/looker_eng.htm in addition to mentioned in paper, following bament forces
toresent data, having appended ascendant sorting by field @a2 
<?mtd name= event=asc  arg=a2/?> following bament forces to resent data, having appended descendant sorting by field
@a2
<?mtd name= event=dsc  arg=a2/?> and following bament forces to resent data, having subtracted sorting by field @a2
<?mtd name= event=none arg=a2/?>
===other SQL5 additions
 in addition to mentioned in pdf-document, each 'select ...' (extracting data into LAN/WAN) is savepoint. DBMS
rollbacksto this savepoint, having obtained bament 
<?back/?>

--
 accepting bament
<?commit/?> DBMS commits current transaction to point of previous 'select ...'

--
 in addition to mentioned in pdf-document, if table "b" below is created
--------------------------
| b1 | b2 |      b3      |
|------------------------|
|         | a1 | a2 | a3 |
|------------------------|
|                        |
|                        |
-------------------------- then expression
IMPLY b/@b3 as b/@b3/@a2; influence so, that any 'SELECT @b3 FROM b' will extract only one elementary field (@a2)
insteadof all branch elementary fields (@a1, @a2, @a3), i.e. mentioned statement will be equivalent to 'SELECT @b3/@a2
FROMb'. it's for multi-language applications (@a1, @a2, @a3 contain notes in different languages) 

--  in addition to mentioned in pdf-document, permissions for field are controlled:
GRANT/REVOKE SELECT/INSERT/UPDATE ON tab/@fld FOR user1;

 DBMS creates separete CSS-file "username.css" for each user "username" in local (for DBMS) directory. table fields are
specifiedas ¶fieldname in it instead of §fieldname, because DBMS does not know, what fields are service (like @colspan,
@rowspan)or are values of properties (like in http://html60.euro.ru/site/html60/en/author/chart_eng.htm), and what
fieldscontain data for visualization - so mark ¶ acts like comment for this xml-attribute 
 all master tables are specified for each slave table in it, i.e. if database table "S" refers to database tables "M",
"N","P", then the following lines are in CSS   
table[name=M] { online:yes }
table[name=N] { online:yes }
table[name=P] { online:yes }
table[name=S] { online:yes; master:M N P } all slave tables are specified for each master table after last column
table[name=M]    ¶m20::after               { online:yes; slave:S1; }
table[name=M]    ¶m20::after::after        { online:yes; slave:S2; }
table[name=M]    ¶m20::after::after::after { online:yes; slave:S3; }
table[name=M][_] ¶m20::after               { content:"s1_fk_comment" }
table[name=M][_] ¶m20::after::after        { content:"s2_fk_comment" }
table[name=M][_] ¶m20::after::after::after { content:"s3_fk_comment" }  all accessable database fields (for user
"username")are listed in this file for 
select * from tab; except fields, which are primary keys in database, and which are always specified (and never
ignored)as invisible 
¶pk           { display: none} if user can update database field, than corresponding xml-attribute will be specified as
re-writable
t             { display: table-row       }
¶t1, ¶t2, ¶t3 { display: table-cell input} /* read-write */ if user cannot update database field
REVOKE update ON t FOR user1; then corresponding xml-attribute will be specified as read-only
t             { display: table-row       }
¶t1, ¶t2, ¶t3 { display: table-cell      } /* read only */ fields, calculated upon other fields and don't saved really,
specifiedin CSS as calculated via @onforminput, implemented in browser as property (pay attention at "§" inside braces) 
¶t1           { onforminput="value=§t2.value*§t3.value" }    CSS-files are available for editing for DBMS
administrator.DBMS does not re-write corrections, made manually.
