| Re: [jpa-dev] [nosql-dev] Ideas about relaunch Jakarta EE at a new level. |
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 Object, the JDO: https://www.oracle.com/java/technologies/java-data-objects.htmlWe've been discussing it several times in the email list, such as this one:
https://github.com/eclipse/jnosql/issues/165
In summary, we can use Oliver comments:We've analyzed also another solution on It such as: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.On Sat, Apr 17, 2021 at 6:46 AM Dmitri Cerkas via nosql-dev <nosql-dev@xxxxxxxxxxx> wrote:_______________________________________________"If I am understanding things correctly, what you are trying to suggest is a generic API for all data access technologies?"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.On Saturday, April 17, 2021, 04:52:47 AM GMT+2, Reza Rahman <reza_rahman@xxxxxxxxx> wrote:I am including the Jakarta Persistence and NoSQL mailing lists as these are the right places to start this discussion.
If I am understanding things correctly, what you are trying to suggest is a generic API for all data access technologies?
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.

I understand the popularity of Java spring.io versus Java EE is 80:20 in favour of spring.
What does the community think is the cause of this disparity and what can be done to close the gap ?
