Our main project, Source Mage GNU/Linux, is an operating system distribution for system administrators, power-users and others who really want control over their systems and want to understand better how "things" work. This is a "source-based" distribution which means that our package installation directly compiles the source code on the user's machine.

Data Pipelines

Data is at the center of everything we do. As each day passes, more and more of it is collected. With that, there’s a need to improve how we accept, store, and interpret it. What role do data pipelines play in the software profession? How are data pipelines designed? What are some common data pipeline challenges? These are just a few of the questions we address in our research.In DZone’s 2022 Trend Report, "Data Pipelines: Ingestion, Warehousing, and Processing," we review the key components of a data pipeline, explore the differences between ETL, ELT, and reverse ETL, propose solutions to common data pipeline design challenges, dive into engineered decision intelligence, and provide an assessment on the best way to modernize testing with data synthesis. The goal of this Trend Report is to provide insights into and recommendations for the best ways to accept, store, and interpret data.

Low-Code Development

Development speed, engineering capacity, and technical skills are among the most prevalent bottlenecks for teams tasked with modernizing legacy codebases and innovating new solutions. In response, an explosion of “low-code” solutions has promised to mitigate such challenges by abstracting software development to a high-level visual or scripting language used to build integrations, automate processes, construct UI, and more. While many tools aim to democratize development by reducing the required skills, others seek to enhance developer productivity by eliminating needs such as custom code for boilerplate app components. Over the last decade, the concept of low code has matured into a category of viable solutions that are expected to be incorporated within mainstream application development. In this Trend Report, DZone examines advances in the low-code space, including developers' perceptions of low-code solutions, various use cases and adoption trends, and strategies for successful integration of these tools into existing development processes.

JBoss BPM Suite Quick Guide: Import External Data Models to BPM Project

Nov 24, 2017 · James Sugrue

Hi Batuhan,


Yes you can, it needs to be imported as part of your project so it's on the path, when this is done you can define a Data Object in the Data Modeller and choose the custom class as the object.


Some of the articles that I wrote that should help:


- http://www.schabell.org/2015/06/jboss-bpmsuite-quick-guide-import-external-data-models.html


- http://www.schabell.org/2015/12/jboss-bpmsuite-data-models-whitelist-imports.html


- http://www.schabell.org/2016/10/modeling-your-business-process-data.html


Hope one helps?
