ObjectDB Database Search

Hi, For last few days I was refactoring my application from standrad ORM aproach to ODB. Everything is fine for now, but I have a question about Explorer. It works only in R/O mode, which in some cases is insufficient for effective work. Is there any plan to release a R/W version of Explorer

Hi, for cascading persist, I have 3 choices: - Either locally (@OneToOne(cascade=CascadeType.PERSIST)) - Either at objectdb level ( ) - Either at JPA global level ( orm .xml).   For defining fetch policy, I know the local way to do it (@ManyToOne(fetch=FetchType.LAZY)). Is there any way

Hi all, I need to persist my application data and also access a legacy RDBMS system in the same Java application. Currently I use Hibernate for both purposes. I've heard ObjectDB is much faster than Hibernate, so I want to try the it to deal with my application data, but I still need some ORM

Here is the description of the problem we are facing:
We have an entity DialogActionNew which previously was located in ObjectDB and recently has been transferred to PostreSQL. We are using ORM Hibernate
When getting this entity from PostgreSQL with the key EntityManager.find(id), we receive

. Could you explain how can I fix this problem? Harman Alexander Golyshkin ORM /SQL annotations are silently ignored

I know you have answered this question some years ago, but I think about the databases that have recently "triumphed" like MySQL, MongoDB or SQLite and they are free databases. Also in the Java world we have the example of Hibernate ( ORM ) and Apache Hadoop (framework for Big Data). In my opinion

Hi All, For some reason I'm not able to make the @OrderColumn annotation work. The test case is attached to the thread. Kind regards Martin1978 Martin Mihalev As stated on this documentation page,  this ORM /SQL annotation is silently ignored by ObjectDB. This is because ObjectDB does not map

Okay, I'll be honest: I thought I am familiar with JPA on top of ORM solutions, but now when moved to ObjectDB I sometimes encounter, let's say, unexpected behavior and I begin to doubt in my JPA-fu. Sometimes I am not really sure if behavior I encounter with ObjectDB is correct or not, although I

Hi In objectdb site i found : Note: This ORM /SQL annotation is silently ignored by ObjectDB so i want  join tow table and generate a third table. Ex:  table 1: employee    table 2: address  and the generate table will be table 3: emp_add employee: e_id, e_name address: add

and eliminates the need for another dependency to an ORM , such as Hibernate, since it implements the JPA ... to avoid coupling it to a specific database. By adding ObjectDB as a database and ORM in a project

that would make it inadequate to do what I want, I just see it as an ORM tool used to awkwardly map

When using JDO without annotations, database sequences are normally defined in the ORM file. Following discussion on the forum I was told that ObjectDB supports sequences if specified in the JDO file. Unfortunately, it doesn't seem to be supported consistently. It appears to work only in
