You have already obtained the L1 and L2 KNIME Analytics Platform certifications and now you want to be certified also for advanced features of KNIME Software for the enterprise context? Then you’re in the right place!
Here you will find all the resources that KNIME provides to be successful for the L3: Proficiency in KNIME Software for Collaboration and Productionizing of Data Science certification exam – we’ll even provide tips and tricks to pass it. First and foremost, the L3 test looks at how KNIME is used within the enterprise environment and checks your knowledge of functionality in KNIIME for collaborating, automating, managing, and deployment workflows.
How to prepare for L3: Become familiar with collaboration and productionization features
The L3 certification exam focuses on all the productionization and collaboration procedures for data science applications, as implemented by KNIME Server.
The certification exam tests your knowledge of:
Collaboration practices, based on versioning, access rights, workflow/node comparison
Deployment of web applications and REST services
Workflow remote execution and scheduling
Productionizing web applications as KNIME data apps
KNIME Server commands and features
Notice that the L3 certification exam does not cover topics pertaining to KNIME Server Administration. For more information on the KNIME Server Administration certification, please visit the KNIME Certification Program.
Study Material for the L3 Exam
You are excited to learn more about this but you don’t know where to start? KNIME offers several educational resources to achieve proficiency with KNIME Server.
1. Self-paced course
Just like the L1 and L2 certifications, KNIME offers a free self-paced course also for the L3 certification exam. You can access and enroll in it, after signing in to your KNIME account, from the KNIME Self-Paced Courses webpage.
The course consists of video tutorials of approximately 5 minutes, divided into 3 lessons and 18 modules going through and explaining all the topics you need for the L3 exam. The 3 lessons covers the following topics:
Lesson 1 is about collaboration features. More often than not, members of a data team need to share data and workflows. Shared repositories and versioning become key to a project's success.
Lesson 2 covers the deployment and productionization part: how to build a machine learning deployment application and how to productionize a general application via the KNIME Server
Lesson 3 concludes with features of the KNIME Server that help monitoring all applications available on the production server.
In the self-paced course, you will find short tests, thanks to which you will be able to verify your progress. Furthermore, there are a few “Hands-on” modules, containing exercises for applying the discussed functionalities.
2. Online Course Covering L3 Topics
The second option to prepare for the L3 certification exam is to enroll into the dedicated online course that can be found in the KNIME Events page, under the section Online Courses.
The L3 online course is run live via a conferencing tool with an instructor, and requires payment. The course includes 4 sessions of 75 minutes each and one 30-minute Q&A session.
The main advantage here is that you will be given the possibility to interact with the instructor, listen to live explanations, discuss exercise solutions, and ask questions during a dedicated Q&A session at the end of the course.
Check when the next course is scheduled and don’t forget to register!
We are also delighted to announce that a new online course [L3-WP] – Productionizing Data Apps will be presented during the KNIME Fall Summit 2022. This new course will place more emphasis on workflow testing, productionization, data app deployment, and orchestration using KNIME Server. Don’t miss the opportunity of being one of the first to attend the new [L3-WP] – Productionizing Data Apps course!
3. L3 Productionizing and Collaboration: Course Slides
If you are not a fan of educational videos, or you don’t have time to sit through a traditional instructor-led online course, KNIME offers a third option.
On the KNIME Course Material Download Page, you can download for free slide decks for each KNIME course. The slide deck of the [L3-PC] KNIME Server Course Productionizing & Collaboration contains detailed explanations of all the topics covered in the L3 certification exam, together with several graphics that help visualize key concepts more intuitively . If you have access to the KNIME Server, at the end of each chapter you have the possibility to test your knowledge with hands-on exercises.
Differences with Respect to L1 and L2
Having already clarified the distinction between KNIME Analytics Platform and KNIME Server, you might wonder whether there are differences between the L1 & L2 courses and the L3 course (and the respective certification exams).
The first two courses aim to help KNIME users gain a solid understanding of the usage of KNIME Analytics Platform, including knowledge of the node functionality, workflow building, and parametrization for different needs and applications.
On the other hand, the L3 course covers what is needed to put the workflows into production. The attention is shifted to address the enterprise necessity for collaboration, automation, management and deployment.
