Your application is deployed and everything is running fine. Great, hi-five! Then out of the blue the phone starts to ring off the hook – it’s users complaining that the application is sometimes ‘slow’. But what does that mean? Sometimes? What tools do you have and what statistics should you be looking at to find and resolve this slowness? Is your system infrastructure up to the task of the user load? What infrastructure design questions should you have asked before you went into production? How can you capacity plan for new hardware with confidence and without over-spec'ing? How can you stop the phone ringing? How could you have stopped it ringing in the first place?
In the first part, I've shown how to start a new project on Django, as well as define new models and add already existing models.
This time, I'll introduce an admin panel, available out of the box and how it can be useful.
Important note: do not expect that if you try to repeat actions from this post it will work for you, it does not. During the article, I had to do some fixes in the django-iris project, and even in DB-API driver made by InterSystems to fix some issues there as well, and I think this driver is still in development, and we will get more stable driver in future. Let's decide that this article only explains how it could be if we would have all done.
In this article, I am trying to identify the multiple areas to develop the features we can able to do using python and machine learning.
Each hospital is every moment trying to improve its quality of service and efficiency using technology and services.
The healthcare sector is one of the very big and vast areas of service options available and python is one of the best technology for doing machine learning.
In every hospital, humans will come with some feelings, if this feeling will understand using technology is make a chance to provide better service.
I was wondering if someone could help me. I do not have docker available to me however a lot of the Open Exchange apps require it. Since I am using a Virtual Windows Machine I can not get docker installed, so I was wondering how to get around this? Someone at GS2022 suggested looking at the docker_compose.yml to figure out how to get around docker, but I am not sure I understand how to read it.
The Demo Day is the result of a four-month journey — the equator of the incubator, in which startups have explored InterSystems tech, validated their ideas and presented it on the first Demo Day. In case you missed it, enjoy watching it on InterSystems Developers YouTube:
Here is the list of presenters with pitch decks of the startups.

Having a recent project to create a FHIR repository, I want to know (as looking at the code) if HealthShare FHIR implementaton supports subscriptions?. I know it records the subscriptions ok, BUT does it handle sending the subscription out (based on the tags) to an endpoint (i.e. when a new FHIR request commits data that would trigger the subscription) ?, I'm 50% it doesn't, but would rather find out for sure before shoe horning something in.
I have an existing DTL and I need to insert a trace statement so that it writes the value of the target object. However, I haven't been successful in completing this.
I have opened the DTL viewer in Studio, and have inserted a trace statement.
Before I begin my writing journey here I wish to introduce myself briefly, so that everyone who reads and follows me will get a clear picture.
To start with I did my Bachelors in Physical Sciences, Mathematics and Computer Science were my core subjects. I have 4+ years of experience in HealthCare Revenue Cycle operations including Medical Coding, Billing, AR Collections, Denial Management and Fincial Reconciliation. Also, 2+ years of experience in Data Operations and Analytics, specifically in Python, PowerBI, SQL and MsExcel.
InterSystems IRIS 2019 is going to introduce new and exciting features. One of the areas with new interesting must-to-know things is the API Management.
I am writing documentation in VS Code, using markdown, and am including some COS snippets in it, e.g.:
```objectscript
[Some COS snippet]
```
The IRIS language server (etc.) is enabled, and classes in the repository this documentation is in, are syntax highlighted properly. However, the code fragment in the documentation isn't. Syntax highlighting for e.g. XML does work.
Am I doing something wrong, or is this not supported?
Following this GitHub we will see how the FIX protocol can be implemented easily using IRIS and Python.
If you don't have much time focus on the Send a Quote before the Order part near the end, as it will, in a matter of minute, tell you how to send a Quote Request followed by an Order Request and show you the result from the server, and that in no more than five clicks.
If one of your packages on OEX receives a review you get notified by OEX only own YOUR package. The rating reflects the experience of the reviewer with the status found at the time of review. It is kind of a snapshot and might have changed meanwhile. Reviews by other members of the community are marked by * in the last column.
An interesting pattern around unique indices came up recently (in internal discussion re: isc.rest) and I'd like to highlight it for the community.
As a motivating use case: suppose you have a class representing a tree, where each node also has a name, and we want nodes to be unique by name and parent node. We want each root node to have a unique name too. A natural implementation would be:
When we collect temporary data (the number of purchases in the store, the number of comments on the post), it may happen that there is no data for a certain period of time. In this case, this time period (hour, day, month) is not represented in the database, that is, there is not a single row for this period. In other words, there are no rows in the database for this period.
In this article, I would like to talk about the spec-first approach to REST API development.
While traditional code-first REST API development goes like this:
Writing code
REST-enabling it
Documenting it (as a REST API)
Spec-first follows the same steps but reverse. We start with a spec, also doubling as documentation, generate a boilerplate REST app from that and finally write some business logic.
This is advantageous because:
You always have relevant and useful documentation for external or frontend developers who want to use your REST API
Specification created in OAS (Swagger) can be imported into a variety of tools allowing editing, client generation, API Management, Unit Testing and automation or simplification of many other tasks
Improved API architecture. In code-first approach, API is developed method by method so a developer can easily lose track of the overall API architecture, however with the spec-first developer is forced to interact with an API from the position if API consumer which usually helps with designing cleaner API architecture
Faster development - as all boilerplate code is automatically generated you won't have to write it, all that's left is developing business logic.
Faster feedback loops - consumers can get a view of the API immediately and they can easier offer suggestions simply by modifying the spec
I have a project that needs to get DSTU2 resources ultimately to CSV files. My thought was if I could get there Resources to R4 I could use the FHIR SQL builder to help map the data. Anyone have ideas? Maybe DSTU2 to SDA to R4...
Is there anyone using this callback in the code? I was searching in the latest IRIS documentation for any handy callbacks of the %Persistent class which allows me to execute some codes just right after a transaction has been committed (TCOMMIT). The description of this %OnSaveFinally() sounds the thing I want because it said:
We have a downstream application that cannot accept more than 500 messages at a time. They want to restrict the number of messages being sent to them at a time.
