#Databases

Hi Team, we are going to deliver a speech on a developer forum where most developers hv not used our tech before but using other database and integration technologies , Pls give us some key points on why they should adopt us and the benefits you can get, especially if you change your tech stack from others to IRIS. Thanks a lot!

In this article, we’ll dive into the inner workings of the database management tool, exploring the architecture and technologies that power it. Understanding how the application functions behind the scenes will give you insight into its design, how it manages databases, tables, and how the API interacts with data.

We're excited to announce a new version release of the SQLTools VS Code extension.

SQLTools connects VS Code users to the most commonly used databases using drivers, including InterSystems IRIS. With over 3.5 million downloads, it is helping users work with their data much more easily.

InterSystems FAQ rubric

You can see the free available space for the database using the radio button "Free Space View" in Management Portal: System Operation > Databases.

And it can be obtained programmatically by the FreeSpace query of the system class SYS.Database.

Found one interesting behaviour in one system with Ensemble. Some Request class has a property with type %XML.CharacterStream by design, this class is the heaviest request in the system, and with profiling journal files, it got about 40% of the file. When I counted all the sizes of such streams per one day and found that the real stored data is three times less.

How can you find referenced entries in a table that have been deleted with the drop column?
I have to find all fields in the database afterwards and then delete them properly.
Has anyone had this problem yet?
Can the information be found in the class or storage definitions?

Thanks for a quick feedback.

Hi Community,

In this article I compared the features of the main leaders in the ODBMS gartner quadrant - 2019. See the list sorted by number of existent features.

What is the best free/open source option to generate the database diagram (MER) to the iris or cache persistent classes?

A More Industrial-Looking Global Storage Scheme

In the first article in this series, we looked at the entity–attribute–value (EAV) model in relational databases, and took a look at the pros and cons of storing those entities, attributes and values in tables. We learned that, despite the benefits of this approach in terms of flexibility, there are some real disadvantages, in particular a basic mismatch between the logical structure of the data and its physical storage, which causes various difficulties.

Hello Community,

Thank you all for your continued feedback and support of our ad hoc reporting platform, VDM. There's been some questions around setting up a non-ODBC connection for InterSystems platforms. We published a new YouTube video showing the steps necessary to connect to InterSystems Caché and InterSystems IRIS with BridgeWorks VDM.

I use rest service on Health Connect and will has utilized HL7 FHIR for get information of external database. But i don't find exemplo in oficial documentation.
Someone to utilize the HL7 FHIR for info request in to external database?

Hi,

If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.

Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance.
%NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.

Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.

Summary

Not sure there are many that connect to MS SQL to execute queries, stored procedures, etc, but our Healthsystem has many different MS SQL based databases we use within the Interoperability environment for various reasons.

With the push to moving from on-prem to the Cloud we ran into some difficulties with our SQL Gateway connections and knowing how to config them to use Microsoft Entra for Active Directory Authentication.
