Transition from Cache to IRIS: Value Canvas

Some clients ask me about migrate from Cache to IRIS. Why migrate to IRIS? Cache is excellent, stable, has good performance. These clients are right, but in the last years, the digital transformation imposed more complete solutions for the new requirements and InterSystems was a visionary to perceive it and launch IRIS.
It is a data platform ready to this digital transformation challenge. To show this, I created a Value Canvas.

In the past, reading information from a bar code was limited to a simple alphanumeric code. The creation of a bar code with more than one dimension (2D), especially the QR Code, allowed to increase the amount and variety of data stored in a bar code. While conventional bar codes are capable of storing a maximum of approximately 20 digits, the QR Code is capable of handling several tens to hundreds of times more information. This revolutionized the markets. Now QR codes are everywhere and can be very useful for storing textual, numeric, alphanumeric and even binary data.

2. DTL: is a component to mapping and transform data between two components in the flow orchestration.

Currently, the process of using machine learning is difficult and requires excessive consumption of data scientist services. AutoML technology was created to assist organizations in reducing this complexity and the dependence on specialized ML personnel.

AutoML allows the user to point to a data set, select the subject of interest (feature) and set the variables that affect the subject (labels). From there, the user informs the model name and then creates his predictive or data classification model based on machine learning.
