Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components.
Due to a new project I'm getting involved inside %Installer stuff deeper than ever I'd be happy to. Most of it was pretty easy to get, thanks to documentation, articles and SAMPLES example, while I can't dig good solution for one problem.
I am still working on a generic task where I need to apply journal file records to another database. Initially I didn't want to use Journal.Restore class methods as I need to perform some data transformation, and it seemed that the clearest way to achieve it was to read journal file record by record using %SYS.Journal.Record API.
If you are facing out the license expire warning message on your terminal ("*** Warning: This Cache license will expire in 3 days ***") and you do not want that message to be displayed, you can disable/enable that by rinning the following commands:
In this session, we will discussing SOLID Principle of Programming and will implement in a example. I have used Cache Object Programming Language for examples. We will go step by step to understand the requirement, then what common mistakes we use to do while designing, understanding each principles and then complete design with its implementation via Cache Objects.
In this webinar, we’ll discuss how you can now easily integrate Apache Kafka within InterSystems IRIS data platform, including via interoperability productions and programmatically via API calls, as both a producer as well as a consumer of Apache Kafka messages:
This summer the Database Platforms department here at InterSystems tried out a new approach to our internship program. We hired 10 bright students from some of the top colleges in the US and gave them the autonomy to create their own projects which would show off some of the new features of the InterSystems IRIS Data Platform. The team consisting of Ruchi Asthana, Nathaniel Brennan, and Zhe “Lily” Wang used this opportunity to develop a smart review analysis engine, which they named Lumière. As they explain:
In computer science, a programming language is said to have first-class functions if it treats functions as first-class citizens. This means the language supports passing functions as arguments to other functions, returning them as the values from other functions, and assigning them to variables or storing them in data structures. Some programming language theorists require support for anonymous functions (function literals) as well. In languages with first-class functions, the names of functions do not have any special status; they are treated like ordinary variables with a function type.
This quick guide shows how to serve HTTPS requests with InterSystems API Management. Advantage here is that you have your certs on one separated server and you don't need to configure each backend web-server separately.
1. Buy the domain name.
2. Adjust DNS records from your domain to the IAM IP address.
3. Generate HTTPS certificate and private key. I use Let's Encrypt - it's free.
PHP, from the beginning of its time, is renowned (and criticized) for supporting integration with a lot of libraries, as well as with almost all the DB existing on the market. However, for some mysterious reasons, it did not support hierarchical databases on the globals.
Globals are structures for storing hierarchical information. They are somewhat similar to key-value database with the only difference being that the key can be multi-level:
We have been using DeepSee which has been the integrated Analytic Dashboard built over Cache Cubes. It works fine but it's visual capabilities are limited and most probably is getting phased out.
If I am not wrong, Tableau is the suggested alternative to DeepSee . It is expensive and a big and considerable shift from existing technology
I wanted to get an opinion of the community as to these few key points
- What other BI tools others have been using with IRIS and what have been their experience
- For which tools are the best inbuilt support / api's avaialble in IRIS
I'm studying AngularJS now ( looking for a substitute for my zen-mojo application ) , I would like to understand how can I connect from the client (AngularJS) with the server , passing data & invoking methods server side.
I was understanding the cluster configuration supported by the Cache. Have couple of queries around that:
1. In Cache version 2018.2, there is a shrading concept which splits the data of a Master Data server into multiple small data server which store shraded data.
