=head1 DESCRIPTION

This is a database layer for Perl scripts, implementing triggers,
record versioning, 
access control at the record level, 
file attachments to records,
materialised views.
There is a web user interface also.

Based on DBI and DB_File data engines. Based on CGI for user interface.

Currently implemented and tested on Win32 Apache and IIS (considering w32IISdpsn warnings).

CGI::Bus, the previous project, was: focused on CGI user interface to database tables, not database metaphor; too complex in record version control programming; too complex and surplus in architecture and setup.

WODA has a very interesting database metaphor, but not many features.

WIKIs are good in hypertext metaphor and records versioning, but may be without database records metaphor, file attachments, access control at the record level.


=head1 CONCEPTS
RELATIONAL DATABASES
Have several disadvantages:

Record Level Access Control
Many of relational databases have not explicit record level access control. It may be implemented via views and triggers, within another application code. Fields for readers and authors names are useful, further needs dependences between records.

=item Temporal Data Model

Many of relational databases have not temporal data model. It may be implemented via triggers and views, within another application code, but see R3 data model architecture...

But it may be useful recognize, who, when, what record edited. Further needs date-times of actuality of record.


=item Polymorph records

Can I query and view data not from concrete tables but from database? It may be implemented via materialized views metaphor, using triggers. Further needs uniform record identifiers, to point to any record from any record, or URL. Full-text queries are also useful.


=item Storage Size

Record types are implemented via database tables. Some tables due to generalization may grow. Very big tables may be difficult in repair or maintenance.


=item File Attachments

May be implemented via BLOBs. But how to attach several files to any record?


=item GROUPWARE DATABASES

Alike Lotus Domino, have several additional disadvantages:

Bad Development Capabilities
There are no triggers, transactions, joins...

=item WEB DATABASES

Have several disadvantages:

Triggers Implementation
All application codes are concentrated at the server. Why programmer needs to use different programming languages to implement triggers and stored procedures in the database and another procedures in the web server? Why user interface hooks may not be considered as a kind of triggers?

Should be interesting a separate 'triggers server'? Or this may be considered as a kind of application servers?


=item Database Engines

Why sole engine should be core? Another data engines or sources may be interesting.


=item WEB COLLABORATIVE TOOLS

Alike Wikis, may include record level access control, file attachments, forms, views and queries, may progress towards database metaphor. But transition from from initial hypertext metaphor to database may require a great effort in implementation.


=item THIS DATABASE

The goal may to be conceptually better then Lotus Notes or to look alike some Wiki, but with remaining ability to implement any relational database and any data source interface.

Any case, this database has several disadvantages too:

Effectiveness
Triggers level implementation is not very efficacious.

One of the problems is repeating cursor loops in recUpd (one for '0R' trigger and one inside dbiUpd) and recDel (for '0R' trigger and dbiDel or recUpd). The last loop is always effectively implemented inside DBI SQL databases, but for DB_Files it should be implemented implicitly inside dbiUpd or dbiDel. To implement efficacious '1R' triggers inside recUpd or recDel, and also for effectiveness of DB_Files, dbiUpd and dbiDel should not be oriented to the groups of rows, or there should be a fast additional single row oriented interface. Also recDel should use a fast single row oriented interface of recUpd. So, there should be two interfaces to recUpd, dbiUpd and dbiDel for effectiveness. But this is difficult in develop and test.


=item Restricted Database API

Database API implements restricted choice of SQL capabilities. SQL is comprehensive, but alien to any host language. It is too difficult to translate host programming to SQL, SQL to triggers implementation, triggers implementation to SQL towards database.


=item Restricted Database Implementations

It is too difficult for embedded Database Engines to support transactions and many SQL features. It is very difficult to implement transactions covering file attachments.

It is very difficult to implement real full-text search and full-text indexing both for database records and file attachments. Existed external indexing machine should understand data records and access rights. Embedded indexing machine should understand formats of files attached. Database may have it's own full-text implementation also.

($self, {command}, {new field => value}, {prev field => value})

Values for 'by-command' triggers are given from arguments of command. Values for 'by-row' triggers are corresponded to a whole record. Previous values are available only in 'by-row' triggers only for existed records. Previous values are not available in recNew and recIns. New valies are not available in recDel. So, new or previous values may be not available is -recForm0R, -recFlim0R, -recEdt0R, -recChg0R, -recChg0W.

Special additional parameters of command may be:

-cmd => command or method name,

-table => table name,

-form => form name or immediate .psp file name,

-cmdf => form metadata,

-cmdt => table metadata,
