We add the Country and Category transactions and specify, in the Attraction transaction, that an attraction belongs to a country and category. We see how GeneXus keeps all related information consistent.
Version: GeneXus 17
GeneXus Core course
We show, in practice, the concept of referential integrity, to maintain data consistency. Introduction of foreign keys relative to primary keys and the significance of calling the corresponding attributes in the same manner. Introduction of the difference between the structure of the transaction and the associated physical table (with the concept of “inferred attributes”). Presentation of the selection list as an object automatically created by GeneXus to facilitate work with related data. We show how it is possible to indicate that a foreign key may have no value, through the Nullable property.

Presentation
Objective:
Through the development of an application, we will teach you the basics of GeneXus that will allow you to understand its logic and quickly build any type of application, now or in the future.
Prerequisites:
Basic programming and database skills. If you do not have them, we recommend that you study this material prior to the start of the course.
Suggested methodology for this course:
Alternate the theory with practice exercises you can download from the “Materials” section.
Watch every video and in parallel do the practice exercises corresponding to those topics, until you have completed all the videos of the course.
Approximate duration:
Theory/Practice: 45 hours (not including the optional "bonus videos" that appear at the end of the course)
If you purchase the course, you will work on it within a study platform (LMS) and you will also have:
Exam:
It is a computer-based exam, with multiple choice and true/false questions and exercises.
When you pass the exam, you will receive an internationally valid “GeneXus Junior Analyst” certification and will be included in the list of GeneXus-Certified Technicians.
