Automation with Drools: Knowledge-Based Decision Systems from Coursera

This intermediate-level project is for business software developers who want to enhance their skills in building expert systems using Drools.

The goal of this project is for learners to showcase their programming and knowledge engineering abilities by constructing an expert system that automates decisions related to traffic violation incidents.

To accomplish this, learners will convert traffic violation rules and policies into a model using Drools. They will then implement business logic using decision tables and verify their model using Drools test cases. Finally, they will deploy their Drools model as an online service and consume it from a client application.

This project offers an overview of the capabilities of Drools and demonstrates its application in solving complex problems across various industries. By completing this project, learners will gain valuable experience in programming and knowledge engineering, as well as a deeper understanding of how to utilize Drools for automating business decisions.

To succeed in this project, it is highly recommended to have experience with flowcharts and familiarity with software development concepts such as variables, classes, and RESTful API calls. Additionally, being acquainted with running Docker images is beneficial.

Reviews summary

Practical drools for decision automation

According to students, this intermediate-level course provides a practical, hands-on introduction to Drools for automating business decisions, particularly through the use of decision tables and rule engines. Learners often highlight the clarity of the instructor's explanations and the real-world applicability of the traffic violation project. While many find the course well-structured and easy to follow, a common point of contention is the technical setup and environment configuration, which can be challenging for some. The course is praised for its project-based learning approach, allowing students to deploy and consume a Drools model as an online service.

Aimed at business software developers.

"As an intermediate business software developer, I found this course perfectly aligned with my skill development needs."

"It's great for those who already have some programming background and want to dive into expert systems."

"The prerequisites mentioned are quite accurate; experience with software development concepts is definitely beneficial."

The hands-on project solidifies understanding.

"The hands-on coding and projects are the strongest part of the course for me; building the expert system was engaging."

"Completing the traffic violation project really helped solidify my understanding of Drools capabilities."

"The structured project approach provided a clear path to apply what was learned, from rules to deployment."

Instructor provides clear and concise guidance.

"The instructor explained complex concepts related to Drools in a very clear and understandable way."

"I appreciated the step-by-step guidance which made it easy to follow along even with new topics."

"The course content was presented effectively, making the learning process smooth and engaging."

Focuses on real-world application of Drools.

"The project on traffic violations was very practical and helped me see how Drools applies to real business scenarios."

"I gained valuable experience in programming and knowledge engineering that I can immediately apply to my work."

"This course truly helps in understanding how to automate decisions using Drools in a practical manner."

"I found the ability to deploy the Drools model as an online service particularly useful for my professional projects."

Environment setup can be complex and time-consuming.

"I spent a significant amount of time troubleshooting the environment setup, which detracted from the learning experience of Drools itself."

"Getting Docker and the RESTful API calls to work correctly was a bit frustrating and could be smoother."

"The initial setup part requires some previous experience with specific tools; it's not entirely plug-and-play."

"I recommend having a solid understanding of Docker and basic backend development before starting to avoid setup delays."
