Overview

Samples-BI is meant for use with the InterSystems IRIS Business Intelligence capabilities. In order to use this sample, you must have an InterSystems IRIS license that includes these capabilities.

These classes provide sample data that you can use to explore the capabilities of InterSystems IRIS BI. They also demonstrate ways to create BI models using InterSystems IRIS BI.

This sample contains two packages:

• The BI package, which provides simple data representing a fictitious medical study, and also provides an InterSystems IRIS BI model that uses that data. See details below.
• The HoleFoods package, which provides simple data representing sales of food products, and also provides an InterSystems IRIS BI model that uses that data. See details below.

The documentation for InterSystems IRIS Business Intelligence refers extensively to these samples. The HoleFoods model provides a quick and easy introduction to BI, and the BI model demonstrates null handling, list-based levels, and other features not included in HoleFoods. The BI package also explicitly demonstrates how to address more difficult modeling scenarios.

After setup:

• You can use the Analyzer to explore these BI models; for information, go here
• You can open the InterSystems IRIS dashboard and explore the sample dashboards and pivot tables. For information, see this
• You can work through the steps of creating a BI model, pivot tables, and dashboards. See this

The repository also includes a number of configuration files and scripts that are not part of the sample itself. Please refer to [dev.md] for more about the role of these files.

Contents of the BI package

This package provides simple data representing a fictitious medical study, and also provides an InterSystems IRIS BI model that uses that data.

• BI.Model package contains the classes that demonstrate BI model capability.

  • BI.Model.PatientsCube is the primary model; this defines the PATIENTS cube that is used in the MDX reference documentation and for most of the sample queries in the documentation. Other classes in BI.Model demonstrate special cases of various kinds; see the BI modeling guides.
  • BI.Model.CompoundCube package contains multiple cube definitions that collectively demonstrate how to create a compound cube. The Advanced Modeling guide discusses these cubes.
  • BI.Model.KPIs package contains sample InterSystems IRIS BI KPIs (key performance indicators). All of these KPIs are either discussed in the modeling guides or are used in the sample dashboards, to demonstrate different kinds of widgets.
  • BI.Model.Portlet package demonstrates a sample custom portlet. For details, see the Advanced Modeling guide.
  • BI.Model.RelCube package contains multiple cube definitions that collectively demonstrate how to create a set of related cubes. For details, see the Advanced Modeling guide.
  • BI.Model.SubjectAreas package contains multiple class definitions that that define subject areas, which are filtered cube definitions. The documentation refers to these in several places. The subject area DEMOMDX (DeepSee.Model.DemoMDX) is meant for use in getting familiar with MDX.

• BI.Study package contains the classes that generate the data used by these models. The most important classes are these:

  • BI.Study.Patient is the central class and provides the source table for the PATIENTS cube. The patients are generated in an age-sex distribution that follows the 2010 US Census data.
  • BI.Diagnosis generates the diagnosis data used when generating patients. This diagnosis data consists of a small set of diagnoses for chronic conditions, along with morbidity data for these conditions (that is, chance of having this condition, based on age & sex). When data for a patient is generated, the patient is assigned zero or more diagnoses, based on the patient's age and sex, using this data.
  • BI.Allergen generates a common set of allergens, and BI.AllergySeverity generates a common set of allergy severities. When data for a patient is generated, the patient is assigned zero or more allergies, each to an allergen, with a specific severity. This enables BI modelers to explore multiple list-based levels and see how they relate to each other.
  • BI.Study.Profession generates a set of professions, to which the working-age patients are assigned.

• BI.Utils.MDXAutoFiltersKPI is a sample class that adds cube-based filters to a KPI, when used as a superclass for that KPI. This class is discussed in the advanced modeling guide.

• BI.APISamples demonstrates how to execute BI queries programmatically on the server. For details, see the BI implementation guide.

• BI.DashboardsEtc contains the pivot table and dashboard definitions based on the models in the BI.Model package.

• BI.Populate contains the wrapper code used to generate the data for this part of the BI sample.

Contents of the HoleFoods package

This package provides simple data representing sales of food products, and also provides an InterSystems IRIS BI model that uses that data.

• HoleFoods.Transaction, HoleFoods.Country, HoleFoods.Outlet, HoleFoods.Product, and HoleFoods.Region generate the data. HoleFoods.Transation provides the source table used by the cube definitions for this part of the sample.
• HoleFoods.Cube defines the HOLEFOODS cube, which is meant as a quick and easy introduction to BI in InterSystems IRIS. The documentation refers to this cube in numerous places.
• HoleFoods.BudgetCube and HoleFoods.CombinedCube demonstrate a compound cube.
• HoleFoods.KPI* classes define sample InterSystems IRIS BI KPIs (key performance indicators). For details, see the advanced modeling guide.
• HoleFoods.SampleListingGroup is a sample listing group class. Via listing groups, you can define detail listings without modifying the cube definition. For details, see the modeling guides.
• HoleFoods.SubjectAreaAsia is a sample subject area. For details, see the modeling guides.
• HoleFoods.Utils contains the code used to generate data for the HoleFoods part of the BI sample. It also contains methods you can use to add or delete data, thus exercising techniques for keeping the cube contents synchronized with the source data.

Setup instructions

Setup with ZPM

ZPM stands for ObjectScript Package Manager. It provides a simple and unified way to install ObjectScript modules Learn More. You can either install ZPM on an existing InterSystems IRIS instance based on these instructions, or use one of the prebuilt Community Edition Docker images that have it pre-installed. The instructions below are for the latter option. If you already have ZPM installed, you can immediately proceed to jump to step 4.

0. Make sure you have Docker-desktop installed.

1. Pull the IRIS Community Edition image with zpm:

$ docker pull intersystemsdc/iris-community:2021.1.0.215.0-zpm

You can take the latest tag of IRIS or IRIS for Health Community Edition with ZPM here

2. Run IRIS container with ZPM:

$ docker run --name irisce -d --publish 52773:52773 intersystemsdc/iris-community:2021.1.0.215.0-zpm

3. RUN IRIS terminal

docker exec -it irisce iris session iris
Node: c6e0f00b8d42, Instance: IRIS

USER>

4. From the IRIS terminal, start ZPM and install Samples-BI:

USER>zpm  
zpm: USER>install samples-bi

5. Open IRIS analytics portal and work with Samples-BI: http://localhost:52773/csp/user/_DeepSee.UserPortal.Home.zen?$NAMESPACE=USER

Step-by-step Installation

1. Clone or download the repository. If you downloaded a ZIP, extract the files to a directory on the server. You will need to refer to these files' location in step 8.

2. If you have not yet created a namespace in InterSystems IRIS, follow the detailed instructions to do so.

3. In the Management Portal, click System Administration > Security > Applications > Web Applications.

4. Click the link in the first column of the row /csp/mynamespace where mynamespace is the namespace from step 2.

5. Click the Analytics checkbox and then click Save.

6. Open the InterSystems IRIS Terminal.

7. Enter the following command (replacing mynamespace with the namespace from step 2):

   ZN "mynamespace"
   

8. Enter the following commands (replacing full-path-to-Build.SampleBI.cls with the full path of the buildsample/Build.SampleBI.cls file):

   do $system.OBJ.Load("full-path-to-Build.SampleBI.cls","ck")
   
   do ##class(Build.SampleBI).Build()
   

9. When prompted, enter the full path of the directory to which you downloaded this sample. The method then loads and compiles the code and performs other needed setup steps.

Now, when you access the Analytics submenu of the Management Portal, this namespace will be listed. For example, you can now use the Analyzer with the cubes that are included within this sample.

IMPORTANT: If the namespace is not listed when you access the Analytics submenu of the Management Portal, see Setting Up the Web Application in the book Implementing InterSystems IRIS Business Intelligence.
