databases

The amount of data collected by applications nowadays is growing rapidly. Many of them need to support both relational SQL and non-relational NoSQL databases. Jakarta Data provides an API to allow easy data access. Developers can split the persistence mechanism and the model using common features like the Repository pattern and seamlessly switch between SQL and NoSQL databases or even use both in the same application.

Faster Data Access with MicroStream

Rudy De Busscher (Payara Services Limited)

Microservices are used more and more but many of them need to access data. Using a database is well established but also slow as data need to be retrieved from an external system in another format and structure and thus requires a mapping.

MicroProfile GraphQL and JPA: Meant for each other

Andy McCright (IBM)

Adam Anderson (IBM)

Can it really be that easy?! Yes it can! Come check out this session where we'll discuss and demo how you can rapidly build data-driven microservices using GraphQL. MicroProfile GraphQL makes it simple to create Java-based GraphQL services with a few annotations. JPA makes it simple to access data in a database. When you put these two technologies together, sparks will fly (the good kind)! With very little code, we can build services that allow clients to get exactly what they want from the database.

Rethinking Data in Reactive Microservices with CQRS

Simon Chemouil (Lambdacube)

Reactive microservices are today's choice to design Cloud Native applications. They promise an increased scalability, resilience and modularity, while allowing separate teams to work on large-scale, polyglot projects. But what about the data?

DBeaver: efficient way to work with SQL and NoSQL from Eclipse IDE.

Tatiana Krupenya (dbeaver.com)

Serge Rider (dbeaver.com)

Most of us, developers, use databases quite regularly.
SQL, NoSQL, flat-files, spreadsheets - it does not matter. We change our databases frequently. But we don't like to change our tools, we prefer to have one solid interface. Best option if our tools are integrated into our favorite IDE.
