Hi Alexey,
Just my 2cents from someone who has not had time to review the code and could not find a breakdown of the firebird code structure in a very cursory search.
> (1) Schema support as per oracle not microsoft (although you can simulate MS style schema with a proper implementation)
> agree, we need schema support
If we have a system table that has the columns (parent, child, type, internal_reference) and had it hold the user facing table names, while referencing a system generated name (the internal reference) that is used in blr and other tasks, then most of the work would be adding a name lookup function to the parser which uses a recursive CTE to do the name matching. This would be the least amount of work and would mostly involve the parser.

This is hard and can wait, because it is mostly making the api's/result sets be bug for bug compatible with the MS platforms

This can wait, but, I do believe it is critical in many work places.

All this needs is some system tables to be created and parser support added. The actual implementation can be written by third parties as long as the tables exist and are documented.

Great news!

Sounds like this would be in 5.0
Overall, things like JSON can be done with packages, stored procs and psql functions, not needing anything from the developers, but the schema and schedular support could be covered by someone who knows the parser well.
Best regards

Hello Dalton,

There is no list of features yet. However, as a member of Technical Task Group, I will work to include into 5.0 the 3 main features: multi-master replication, partitioning/table spaces, schema support.
>I have been a supporter of firebird for years but there are several things that hold it back
My opinion:
(1) Schema support as per oracle not microsoft (although you can simulate MS style schema with a proper implementation)
agree, we need schema support
(2) Cube SQL support
would be good, but not critical
(3) Linked Databases in addition to the psql connections
would be good, but not critical
(4) Jobs with Schedular
would be good, not critical, can be implemented with bundled product (not core)
(5) Replication
Master-Slave is already in HQbird for 2.5 and 3.0, and will be in community Firebird 4.0
Master-Master is the next step for 5.0.
(6) High Available ClusteringRegards,
agree, it will be based on top of the replication.

Thank you!
In my opinion, Firebird will close the gap with PG in main features in 2
years, with FB5.0 version.
