or "So you just got yelled at by your boss, for sending him an unformatted Hello World webpage"
Our previous lesson ended with us serving a Message value obtained from a Caché REST service to the client, using Angular as a runtime. While there is a lot of moving parts involved in this process, the page is not especially exciting at the moment. Before we can start adding new features, we should take a step back and review our tools.
For those of you who might be new to IRIS, and even those who have used Cache or IRIS for some time but want to explore beyond its usually-assumed boundaries and practices, you might want to dive into this detailed exploration of the database engine that is at its heart, and discover just what you can really do with it, going way beyond what InterSystems have done with it for you.
Recently, I needed to create templates for newsletters. I couldn't find any tools, so I decided to use the CSP (Caché Server Pages) to build the templates.
Let's figure out how to make a newsletter similar to Weekly OEX Digest.
For those that, at some point, need to test what means that of ECP for horizontal escalability (computing power and/or users and processes concurrency), but they're lazy o have no much time to build the environment, configure the server nodes, etc..., I've just published in Open Exchange the app/sample OPNEx-ECP Deployment .
If one of your packages on OEX receives a review you get notified by OEX only on YOUR package. So @Evgeny Shvarov suggested publishing my monthly summary of my reviews here in DC. It reflects my experience with the status I found at the time of my review.
After >40 years of writing in-countable lines of code in M*/COS/ISOS (and a bunch of archaic languages) I decided for myself to set a strong signal for the future. We have Embedded Python available (still pre-release)! I just felt it as a sacrilege to ignore this excellent NEW opportunity and stay with the old sermon that I had used for decades.
to dismount/mount a database, use Dismount() and Mount() methods in SYS.Database class available in %SYS namespace. NB: the database ID is its Directory
You'll find some examples of how to dismount/mount and check if a database is mounted (Mounted=1) or not (Mounted=0), and quickly see all the attributes of a database (via zwrite)
One of my colleagues had developed an interface in Health Connect (HealthShare 2019.1) to add large amounts of data to an external SQL Server database. The data comes from many text files with delimited rows and data for one table per file. There is a business process to read a file line by line and send an Insert Request to an operation.
As you can see in my profile I teach at a university and I wanted to share my take on teaching IRIS (or Caché before it).
It’s been some time but I remember seeing a series of articles by @Yuri Marx earlier this year about the course “Developing with InterSystems Objects and SQL”. He actually gave a brief description of what’s done on Day 1, Day 2, and Day 3 with comments from instructor @Joel Solon. And I thought to myself, it may be interesting to share my experience.
What about having your IRIS REST APIs scanned every push you did and being reported on possible vulnerabilities? This is what I am going to show you in this article.
Have you tried the InterSystems learning platform lab for IRIS IntegratedML? In that lab you can train and test a model on a readmission dataset and be able to predict when a patient will be readmitted or not, or calculate its probability of being readmitted.
You can try it without any installation on your system, all you have to do is start a virtual lab environment (Zeppelin) and play it around!
I was editing the properties of a persistent ObjectScript class the other day and noticed that the storage definition wasn't updating to reflect my latest changes.
In this case, I deleted a property that was no longer needed from the class definition, saved, recompiled, and still saw it in the storage definition.
Millions of professionals use a wonderful tool, spreadsheets, for engineering calculations and financial analysis. It attracts a user-friendly interface and clear data organization. Cell formulas provide rich opportunities for automating calculations. No programming is required.
The 2021.2 release of the InterSystems IRIS Data Platform includes many exciting new features for fast, flexible and secure development of your mission-critical applications. Embedded Python definitely takes the limelight (and for good reason!), but in SQL we've also made a massive step forward towards a more adaptive engine that gathers detailed statistical information about your table data and exploits it to deliver the best query plans. In this brief series of articles, we'll take a closer at three elements that are new in 2021.2 and work together towards this goal, starting with Run Time Plan Choice.
It's hard to figure out the right order to talk about these (you can't imagine how often I've reshuffled them in writing this article!) because they fit together in such a nice way. As such, feel free to go on a limb and read these in random order .
This is the third article in our short series around innovations in IRIS SQL that deliver a more adaptive, high-performance experience for analysts and applications querying relational data on IRIS. It may be the last article in this series for 2021.2, but we have several more enhancements lined up in this area. In this article, we'll dig a little deeper into additional table statistics we're starting to gather in this release: Histograms
Need to change your PRIMARY email address (login email) and not lose all your activity on the Developer Ecosystem resources: Community, Global Masters, and Open Exchange?
It's easy! We will take care!
1️⃣ We will correctly transfer all your information from the old DC account to the new one.
All your posts, comments, mentions, likes, etc. will be saved on the new account.
What if you could check if your REST application is susceptible to some vulnerability? What if you could check if any known attacks affect your application?
With these issues in mind, we've brought our sample application using the ZAP testing tool. A way to quickly, conveniently provide tools for developers to validate security issues in an accessible manner practically.
The InterSystems IRIS has a great audit system. It is responsible for auditing system events, but you can use it to audit your applications (great feature).
The audit system is based into event concept. The events can occur with IRIS or in an application. So, we have two type of events to the audit system:
1. System events: events occured into the InterSystems IRIS components (database, interoperability, analytics and core);
DTL Transformations and GetValueAt/SetValueAt calls on HL7 messages will truncate any fields longer than 32K. To avoid this, the methods GetFieldStreamRaw and StoreFieldStreamRaw must be used when dealing with fields that might be larger than 32K. OBX:5 is a frequent example. These methods have some subtleties and must be used carefully.
This can't be done by simply dragging from left to right in a DTL. It must be done with a code action. Also, the StoreFieldStreamRaw call must be the last edit made to the segment because the segment becomes immutable after that.
