Mapping of classes, routines, globals to Namespaces.

Article Lorenzo Scalese · Apr 4, 2022 6m read

Hi Community,

This article describes the small ZPM module global-archiver.
The goal is to move a part of a global from a database to another database.

Why this package?

A typical use case is read-only data sequentially added to your database that you can never delete.
For example:

  • User log access to patient medical data.
  • Medical documents versioning.

Question Chip Gore · Aug 18, 2016

I'm VERY novice on all things "OpenAM", and beyond knowing that Caché supports working with OpenAM, I have nothing else to go on.

The documentation doesn't seem to be very deep on the nature of how this works beyond a single paragraph saying it's supported for Single Sign On (SSO).

For Caché to use this, I get that there is an environment variable (REMOTE_USER) which is set to "something", but it's not clear to me how this ends up mapping to a provisioned caché user (or LDAP provisioned user for that matter) and ultimately to the %Roles in effect and subsequent system access.

您好,我想问一下为什么我无法通过Iris中的内置转换模板将从HAPI-FHIR服务器下载的患者资源转换为SDA格式。它总是表明缺少某个默认值,或者这就是我们需要更改格式吗?我想问一下我们如何快速创建自己的映射,以及如何通过json将所需的数据转换为sda并将其存储在iris中,然后我们可以通过齐柏林飞艇进行调用,非常感谢您解决我的问题问题

Question Carl Emberger · Apr 5, 2021

My dilemma is that I'm working with a file that has three different data records plus the header and trailer.  The record type is in positions 21-23.  The header and trailer have spaces in positions 1-20.  The data records have a variable data in positions 1-20.

I tried to use pattern matching in the leading data field however that field is treated as a literal string for matching.

Header Row                             000

Data Row 001       139459911           001

Data Row 002       139459911           002

Data Row 003       139459911           003

Data Row 001       139459044           001

Question Michele De Chiffre · Mar 11, 2021

I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />

My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.

Question Oliver Wilms · Dec 7, 2020

Hello,

I like to know if we need to have the message in a file to process a Record Map?

I am working with Interoperability Production that processes files /messages using Record Maps. My team was asked to redesign the solution for deployment in AWS. We use containers. We had problems with having multiple containers processing files from the same directory. We are considering Amazon Simple Queue Service instead of having files on a shared file system.

Has anybody migrated a Record Map to a Schema Definition to validate a message as a Virtual Document as I have seen with X12 messages?

Question Lawrence Williams · Aug 23, 2019

I am putting together a new interface to take in a CSV file and output an HL7 message.

I have used the record mapper to create the source class and I am putting together the transform, but when trying to test it I am not seeing the data populate the HL7 as intended.

Also.... if I put a <DatofBirth> in the tester, it shows up in the HL7 as I would expect..... that's what really has me scratching my head here.

In MX any global can be displayed on a sheet in the form of a table.

We will look at the simplest example (work only with  CACHE-2014+ or IRIS)

Upgrade or install  MX.

Start mx.xlsb  and connect to your namespase with vmx-routines.

After opening first sheet, click button  []   ##class(SYS.Stats.Dashboard).Sample()

Then press button [design-mode]   (top of screen ).

You will see something like this in the top four lines:

M-Formulas works in cells in the process of opening this sheet,  step by step :

Question Arto Alatalo · Apr 15, 2020

If two globals have same structure, how to reuse one CacheSQLStorage-based class to read both locations?

Thanks!

Update:

Let's say we have two globals:

^a(1)="dataa1"
^a(2)="dataa2"

and

^b(1)="datab1"
^b(2)="datab2"

i.e. the structure difference is global name only.

I would like to have two classes TableA and TableB both are inherited from TableAB, and TableAB taking global name as a parameter.

Question Nauris Gruduls · Mar 12, 2020

In my Data Transformation, the Target class needs to create a new List of objects (ListOfObj), depending on some conditions of Source class (Source/Target are completely distinct/different classes).

I experimented with Lists of 'primitive' data types (ListOfDT), and I could add new %String items (as an example) to a List of %String property, with "append" action in DT.

Does anyone have an example, or guidance, how to create new Lists of Objects in data transformation?

For example, if I have a 'container' class like this, it works:

What if you could serialize/deserialize objects in whatever format: JSON, XML, CSV,...; attending different criteria: export/import some properties and not others, transform values in this or that way before exporting/importing,...; and all of this without having to change the class definition? Wouldn't that be great??

Well, perhaps it's a goal too ambitious to reach 100% but, exploring this idea, I've developed a bunch of classes that I thought it was good to share. If you want to test, change, modify or improve the code, or just take a look at it, you can do it here. There you'll find a more detailed explanation (see Readme.md)

Be aware, this is a proof of concept for myself done in spare times, sure it's not robust enough or it can be done much better... but, I was just playing...ok, I could just wait to the new JSON Adaptor (coming soon!) that sure is going to resolve much more scenarios in a cleaner way, but... meanwhile... :-) ...

Hi, we are a veterinary lab and we use both the LAB and FIN systems of Antrim. Now we are looking to expose the data in a SQL/Object compatible way so we were wondering if same / similar things had been done by other community members already? If so, could you please share your approach / experience / gotchas with us and we are all ears. I can be reached at yang.jiao@antechmail.com . Thank you!

The InterSystems DBMS has a built-in technology for working with non-structured data called iKnow and a full-text search technology called iFind. We decided to take a dive into both and make something useful. As the result, we have DocSearch — a web application for searching in InterSystems documentation using iKnow and iFind.

How Tax Service, OpenStreetMap, and InterSystems IRIS
could help developers get clean addresses

 

Pieter Brueghel the Younger, Paying the Tax (The Tax Collector), 1640

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.

Question Alexey Maslov · Jan 31, 2019

Sometimes global mapping of the same globals can be defined in different ways. E.g., I need to define it for 3 globals ^qAuditC, ^qAuditLog, ^qAuditLogC from the same database named APP-NOJOURN. Which approach should be better from the performance point of view?

1) qAudit* => APP-NOJOURN (one record in global mapping table)
or

2) qAuditC => APP-NOJOURN
qAuditLog => APP-NOJOURN
qAuditLogC => APP-NOJOURN (three records in global mapping table)

The following post outlines an architectural design of intermediate complexity for DeepSee. As in the previous example, this implementation includes separate databases for storing the DeepSee cache, DeepSee implementation and settings. This post introduces two new databases: the first to store the globals needed for synchronization, the second to store fact tables and indices.

It's well-known that namespace global mapping helps us to write code independent on database storage details (Caché instance name, directory path). But sometimes we can face problems accessing an unsubscripted global which has subscript level mapping (SLM) defined. Most of such cases are evident and associated with administrative tasks that should be done on database level, but some of them can confuse even an experienced developer. Just to start:

  • We can't export such a global using Caché Block format (a.k.a. GOF).
  • We can't kill such a global.

Maybe you can continue this list.

The following post outlines a more flexible architectural design for DeepSee. As in the previous example, this implementation includes separate databases for storing the DeepSee cache, DeepSee implementation and settings, and synchronization globals. This example introduces one new databases to store the DeepSee indices. We will redefine the global mappings so that the DeepSee indices are not mapped together with the fact and dimension tables.
