Hello, friends who are developing IRIS. I recently participated in the InterSystems Developer Tools Contest. This time, I made a tool based on the idea described in an article I published earlier as a template for quick query of messages. Currently, you only need to establish entity classes in IRIS, Then record the message corresponding to the entity class in the specified lookup table, and all the key fields generated in the message can be inverted indexed (the concept in ElasticSearch), which is convenient for quick query. The following is the design idea of my program.
