Presenter: Jeff Semmens
Task: Model and access data as objects in .NET without designing the database first
Approach: Use InterSystems Entity Framework

Description: Come and experience how you can design your database model in .NET and evolve it over time by leveraging the Entity Framework.

Problem: Current bindings require database-first design. I cannot design my model in .NET.

Solution: The Entity Framework is an object-relational mapping framework that allows data-oriented applications to model and access their data as objects in .NET. Database- first is still supported but will fade away in future releases.

Task: Validate your performance and scalability claims, detect and correct bottlenecks, or determine the hardware needed to optimally run your applications
Approach: Discuss and demonstrate the use of our WebStress feature to design and run benchmark tests of your HTTP-based applications.

Conducting benchmark tests of your applications can help you highlight your performance and scalability claims, detect and correct bottlenecks in your application, and provide useful information about the hardware required to optimally run your solutions. Come to this session to learn about our “WebStress” feature that can help you design and run benchmark tests of your HTTP-based applications.

Task: Upgrade with minimal downtime
Approach: Provide examples of planning minimal-downtime upgrades from a variety of starting scenarios

When upgrading Caché, Ensemble or your application on your business-critical system, you want zero or minimum downtime. This session explores the problems and options when upgrading, and how mirroring can reduce or eliminate business disruption, with practical steps and a demonstration.

Task: Avoid bottlenecks caused by scaling up, before they become a problem
Approach: Discuss what operating system and InterSystems metrics you should look at and how to interpret them

Systems behave differently when database activity scales up. In the worst case, bottlenecks appear and users are impacted. This session shows you which operating system and InterSystems metrics you should be looking at and how to interpret them so you can head off bottlenecks before they impact users. This sessions also shows strategies for planning infrastructure taking into consideration InterSystems' data platforms requirements.

Task: Take advantage of the NoSQL paradigm without adding another tool
Approach: Provide sample use cases that are an excellent fit for InterSystems’ new document data model

Description: Designing applications always requires you to make assumptions about your data model. Come to this session to learn how you can effectively handle the cases where you have to rapidly evolve your model. We will also discuss other use cases that are an awesome fit for the flexible document data model.

Problem: I’ve observed the NoSQL landscape and like the direction, but I have no use-case that fits and I do not want to add yet another tool.

Solution: InterSystems now has support for a well integrated document data model that brings the NoSQL paradigm to the enterprise within your current stack.

Here is a screenshot from my 2016.2 FT instance of Studio and Ensemble:

I don't recall having seen the highlighted "+" suffix on document names previously. Who can tell me what it denotes?

I originally posted this in the Field Tests group but it turned out to be a 2016.1 feature that I hadn't previously noticed. So I subsequently moved the post to the Cache group.

Hi -

I'm trying to create a method that will automatically create something I can save and use later, which will let me automate data migration from one version of a class to the next.

Hello all,

I know it is perhaps too vague question, but anyway:

Do you have experience from running a thick (preferably .NET) application in any of these modes - client installed locally, Terminal Server, Citrix ? Say, there are around 300-400 concurrent users using application.

Can you share your observations / opinions?

Thank you!

I am pleased to announce that Caché and Ensemble 2015.2.3 are now available as maintenance releases.
For a complete list of the corrections in 2015.2.3, please review the release notes.

Caché and Ensemble 2015.2.3 are available now for the same platforms as 2015.2.2

The complete set of supported platforms, including specific point releases and/or patches, is detailed in the Supported Platforms document.

Hi,

I am working on a DataGrid based upon ZenTest.Datagrid.cls

I want to save data after changes on a row.

The existing samples do not explain how to save changes on data in a grid.

I have tried something like zen(‘json’).save

Does anybody has some sample code?

I have existing projects in my Atelier environment. Where can I go to see which namespace they were created in?

Hi all,

I've been looking for a way to extract the sorting from the ^CacheTemp.zenData global that contain the tablePane snapshot data in order to use it on a report following the current UI sorting criteria.

I could see that if the column is sorted by one column, new entries with this structure are created:

^CacheTemp.zenData(<sessionId>,<snapShotId>,<tablePaneId>,"index",<columnId>,<value>,<dataId>)=""

Previously I showed you how to run pButtons to start collecting performance metrics that we are looking at in this series of posts.

Hi!

There is an example in Samples which shows how to implement 'running total' measure: "Pareto Chart for Category" dashboard.

To calculate running total this pivot uses calculated measure with %Cell expression:
