This is a public announcement for the first release of Intersystems Cache Object-Relational Mapper in Python 3. Project’s main repository is located at Github (healiseu/IntersystemsCacheORM).
About the project
CacheORM module is an enhanced OOP porting of Intersystems Cache-Python binding. There are three classes implemented:
CacheClient This is the super class of CachePython module. It wraps two functions from intersys.pythonbind module pythonbind3.connection() and pythonbind3.database().
CacheQuery A subclass of CacheClient that wraps methods and adds extra functionality in intersys.pythonbind.database and intersys.pythonbind.query classes
CacheClass A subclass of CacheClient, that wraps methods and adds extra functionality in intersys.pythonbind.database and intersys.pythonbind.object classes
The intersys.pythonbind package is a Python C extension that provides Python application with transparent connectivity to the objects stored in the Caché database.
Source Code
The project’s code that is released to the public was originally written and used as a module of TRIADB project.
Tests and Demos
There are two folders in this release:
testCacheORM contains python jupyter notebook files that demonstrate CacheQuery and CacheClass
testCacheBinding are tests written for Intersystems Cache python binding
One can simply compare tests with demos to appreciate the work in this project to leverage intersystems cache python binding.

Although there has been significant progress with first and second generation AI systems in reasoning, learning and perceiving, abstraction has not been part of the game. The mechanism of abstraction can unify these other three processes.

Qlik Associative Model
Qlik's competitive advantage over other BI tools is that it manages associations in memory at the engine level and not at the application level. Every data point in every field of a table is associated with every other data point anywhere in the entire schema.

Association in RDF Data Model
In this article we will see how we can define an association in RDF and what are the differences with other data models that we analyzed in previous posts of our series
Do you Understand Many-to-Many Relationships ?
Associative entities are represented differently in various data models
It is 2016 and in my opinion the situation with associative entities has become darn confusing. Edges of a Property Graph data model are bidirectional but RDF links are unidirectional.

In this article, we continue our investigation with the Property Graph Data model. We discuss how a many-to-many relationship is represented and compare its structure in other data models

Association in Topic Map Data Model
In this post, we demonstrate how Topic Map data model represents associations. In order to link the two, we continue with another SQL query from our relational database
