Hey, how are you?
Thank you for including me in this discussion.
Indeed, in Java history, we have this kind of API: the Java Data

Both did not go further because NoSQL has a huge difference. Besides,
there are a couple of details in the NoSQL world, such as MongoDB has
transactions; however, we need to think twice because of the
performance issue. Also, there is Cassandra, who does not provide
transactions at all, and so on.
Summary, when we a boat API and move it on the plane just because both
are transport tends to be a bad idea.
I'm glad to help on it, and yes, once both are persistence API, we can
think about how we can work together, such as a standard way to follow
the Third Factor App and so on.
Please, let me know if you wanna do a meetup by hangout or zoom.

Yes, this is my idea.
1) if any database (SQL or NoSQL) is a storage for: connect to
it, write (insert), read (select) and modify (update) of data,
2) taking in account that now JDBC allows users to work with
different RDBMS (SQL) databases by: connecting to them,
writing, reading and modifying data,
3) and taking in account that now users accessing data via
JDBC write custom queries sutable for a specifical database
(queries for DB2 are not identical to the queries for Oracle DB)
why not allow users to:
1) write connection string for connecting to NoSQL database as
well,
2) write custom queries for select-insert-update-delete data
in that particular DB ?
Data can be always represented by java objects (both in the
case of SQL DB, "linear NoSQL DB" or "XML NoSQL DB") (in the
case of XML NoSQL databases the structure of data (I mean
Java-side) can be similar to X-stream approach).
There are always be "PreparedStatement", "ResultSet" and
"executeQuery", but on an extended level - users will have the
possibility to query "NoSQL DB".
Maybe I don't perceive the underlying problems because of my
ignorance, but if that problems can be overcome we will have a
universal (multipurpose) Jakarta DBC for ALL database types
similar to that as was JDBC for ALL RDBMS (SQL) database types.
Thank you,
Dmitri.

I am including the Jakarta Persistence and NoSQL mailing lists
as these are the right places to start this discussion.

This is an idea that I believe in particular has been well
discussed at least by Otavio Santana. The practical problem is
that it is very difficult to arrive at one API that suits all
data storage technologies adequately. Indeed it is very
difficult even to arrive at one API for all NoSQL taxonomies.
That said, I know folks involved have expressed interest in
having at least a common set of annotations - which is more
achievable. Perhaps the folks in the respective aliases can
share the current thoughts on the topic?
Hope it helps?

Please note views expressed here are my own as an individual
community member and do not reflect the views of my employer.
P.S.: JDBC is a Java SE technology defined by the JCP, not a
Jakarta EE technology. I don't think there are any plans to
move JDBC to the Eclipse Foundation or evolve it to cover NoSQL.

Hi Reza,
may be you remember me - I'm Dmitri - you are keeped me in
touch with "Jakarta EE Tutorial" group and I am very grateful
to you for that - thank you! My last activity in the Jakarta
EE Tutorial team was the full recreation of all images from
PNG to SVG format and I pushed all 68 images in a new format
yesterday! :)
Soon I'll review whole tutorial, because, in my opinion, some
paragraphs are structured no so well and are not quickly
understandable.
Thank you again for opportunity!
About my idea of how to relaunch Jakarta EE to make it the
standard even wider thean now in the field of Information
Technology - I think it's necessary to review all Jakarta's
components to make them global (multipurpose).
For example, JDBC that now is valid only for SQL-databases can
be trasformed in something like "Jakarta DBMS" standard (or
DBIS (database interacting standard)) capable of interacting
with ALL types of databases (RDBMS, SQL, No-SQL, ecc). This
can involve upgrade of some components of Jakarta EE, for
example, EJB, JPA, JTA to become universal (multipurposal).
I'm Java Developer Master with 6 Oracle's certificates in
Java, Database Administrator Certificated, Linux System
Administrator Certificated and now I'm preparing for Software
Architect certification.
If you like my idea I can start analyse the possibility of how
JDBC and various related components can be upgraded for
working with ALL types of databases.
After that we can analyse other Jakarta EE components of how
expand their use globally.
Thank you,
Dmitri.
