Currently, i am doing DB Migration from SQL to NOSQL Db in spring boot application
I am looking for equivalent way of "#Embeddable" in cassandra 3.x or 4.x

How can I use both in same SpringBoot project? Will it not create conflict which one is going to create tables?
Liquibase is Version Control System dedicated for track, version, and deploy database schema changes.
Hibernate is an object-relational mapping (ORM) tool for the Java programming language which provides a framework for mapping an object-oriented domain model to a relational database.
Yes of course you can use both in same Spring Boot project. Check this official guide liquibase + Hibernate for Using Liquibase with Hibernate.
I am new to Spring and Hibernate. I have a project using Spring, Hibernate and PostgreSQL. I know that I can query the database using Spring Data JPA or Hibernate, but I don't know what the benefits and disadvantages of each approach. I also know that in the background, Spring Data JPA will call Hibernate. So what is the best way I should use to query the database to get the best performance, Spring Data JPA or Hibernate or depending on the specific usage situation. Thanks very much
I think it is based on the requirements of your project.
You can find more answers to this question at StackOverflow.
hi I am trying to update and delete the data in my application in spring boot and I came to know that postgresql is quite different from normal SQL can you provide the correct syntax for the update and delete operations in postgresql for spring boot application please I couldn't find it in internet.
If you use Spring Boot you actually could use Spring Data for creating queries and you'll not need to write queries by yourself.
In my project, there is a requirement to use different databases. We are currently using MySql database with Hibernate as ORM layer. And we are hibernate SessionFactory to query the database.
Now there is a requirement to use SQLite database as well. I have found several examples on the internet but they are all using JdbcTemplate.

But my requirement is to use separate sessionFactories for both the databases.
Please, help me in receiving that.
as it is stated at http://static.springsource.org/spring/docs/2.0.8/reference/orm.html
The Spring Framework provides integration with Hibernate, JDO, Oracle TopLink, iBATIS SQL Maps and JPA:
My question here is does not spring provide ORM support for JDBC?
Spring supports JDBC, and includes helper objects to map resultsets to objects, if that's what you mean. It's not listed on the page you link to because it's not considered to be an ORM. (Actually Ibatis isn't considered to be an ORM either, it's a "data mapper".)
