In this article I would like to present the RESTForms project - generic REST API backend for modern web applications.
The idea behind the project is simple -after I wrote several REST APIs I realized that generally, REST API consists of two parts:
Work with persistent classes
Custom business logic
And, while you'll have to write your own custom business logic, RESTForms provides all things related to working with persistent classes right out of the box. Use cases
You already have a data model in Caché and you want to expose some (or all) of the information in a form of REST API
You are developing a new Caché application and you want to provide a REST API
Good afternoon! I faced a problem with HealthShare complete transfer to another PC. I have on the old computer a lot of interesting developments and test projects, including widgets, developments on DeepSee and other stuff. Would you please describe the details how one HealthShare installation can be correctly transferred to another PC. And that this should be done.
The purpose of this post is to ask for everyone's thoughts and input around the use of transient, SQLCalculated/Computed properties within persistent classes.
This approach allows for extra data values needed in SQL queries to be available without having to join to other tables.
Very simple/basic example to illustrate the topic:
Let's say I have a persistent class named ICDAutoCodeDefn to hold ICD Auto-Coding definitions, such as:
If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.
If the above does not sound familiar to you please start at the beginning with the following:
I have a class which defines a property as array of %String. Is it possible to index values of this property and use this property in SQL?
I have tried 'Index idx On prop(ELEMENTS)' and then a select from the generated collection table, but this is still orders of magnitude slower than queries to the containing class.
This post provides guidelines for configuration, system sizing and capacity planning when deploying Caché 2015 and later on a VMware ESXi 5.5 and later environment.
Hello. I am a student from Syktyvakar Forest Institute(Russia).
I need to make Research : "Databases for working with spatial data Consider MySQL, PostgreSQL and 1 to choose from". I want to explore Cache with subject library of spatial data.
Help.
Does Someone from the developers write the libraries of spatial data?
Coming from a C/C++/C# background, I was expecting the & and | operators in Cache ObjectScript to perform bitwise operations on integers, but apparently they don't.
I have to receive GPS tracks through a TCIP port using SOCKET listen port from INTERNET, how can I implement this in CACHE? through websocket ?. Thanks if you can help me.
to connect job on one MUMPS server to other job on other MUMPS server in client-server mode. This tool can connect different MUMPS systems on different OS and with different processors - MiniM, Cache and GT.M in any pairs.
Hyper-Converged Infrastructure (HCI) solutions have been gaining traction for the last few years with the number of deployments now increasing rapidly. IT decision makers are considering HCI when scoping new deployments or hardware refreshes especially for applications already virtualised on VMware. Reasons for choosing HCI include; dealing with a single vendor, validated interoperability between all hardware and software components, high performance especially IO, simple scalability by addition of hosts, simplified deployment and simplified management.
A calculated measure is a powerful feature in DeepSee and can help to enrich your analyzes. In the case of complex or long running computations plugins can be useful. This article shows with a simple example how you can build and use a plugin in DeepSee.
Just curious how many companies use in their work Docker containers, I mean not only with InterSystems products. And if such companies exist, which of them uses docker and doesn't use it for InterSystems products by some reasons. What are the reasons? For companies which already uses InterSystems in containers, how do you use it? Development environment, testing or even in production ?
And if you don't use but thought about it, what are the reasons which stop you.
As for me, I've been using InterSystems Caché inside a Docker container in some different cases:
I know that when specifying Caché password rules (i.e. what constitutes a valid password definition) that the "Pattern Matching" logic is what is getting leveraged under the covers to enforce the "A Password Must conform to X" rule. I was hoping that people could share some more sophisticated pattern matching rules. (in particular, I was wondering what a rule that would require non-repeating mixture of letter, numbers, & punctuation of an overall minimal size)
I have a Zen page, and I would like to have an onload handler to run a bit of javascript when the page is ready. Unfortunately, the page inherits from a template, and the template already has an onload handler that does all kinds of useful things. Is there any way to override the onload handler in my page, while still being able to call the onload handler that is inherited from the template? In ObjectScript, there is ##super, but in javascript, there is no equivalent of that.
When creating a filter located on a dashboard that targets all, is there a way to narrow that filter down?
For example, in our data we have some dates that are well out of range due to data quality issues, but they still appear in the drop downs. Is there a way to say, only make available the below dates in the filter?
Another example, If we want to only look at Emergency data, it still provides all the wards for inpatient activity and activity in other hospitals, meaning, to get to just the Emergency wards you have to scroll through everything?
We have a development instance of cache that was installed and the person that installed and set it up is no longer here. We have no id's that we have the passwords for. I have brought the database up in emergency mode and I can get access thru the terminal using my emergency id but I do not know how to add a user/password thru the terminal. Can someone enlighten me or point me to documentation that I haven't found yet.
We tested REST Services as described for Caché DocServer example and for requests using http protocol it works without problems. However when we use the https protocol for the same REST Service it is not available. Our infrastructure is as follows: Apache with openssl, which works on the other hand well for CSP with https. If we switch on the web gateway http trace facility we could see the request of CSP pages by https://... but again a request of a REST Service by https:// will not result in a entry in the tracer. We hope that this description of the problem is understandable.
