#Data Import and Export

Thanks to @Yuri Marx we have seen a very nice example for DB migration from Postgres to IRIS.
My personal problem is the use of DBeaver as a migration tool.
Especially as one of the strengths of IRIS ( and also Caché) before is the availability of the
SQLgateways that allow access to any external Db as long as for them an access usinig
JDBC or ODBC is available. So I extended the package to demonstrate this.

Hi folks!

Sometimes we need to import data into InterSystems IRIS from CSV. It can be done e.g. via csvgen tool that generates a class and imports all the data into it.

But what if you already have your own class and want to import data from CSV into your existing table?

There are numerous ways to do that but you can use csvgen (or csvgen-ui) again! I prepared and and example and happy to share. Here we go!

This article is a follow-up to the previous one on how to migrate from popular databases (like PostgreSQL and MySQL) to IRIS.
We will use the same procedures utilized to migrate from PostgreSQL. However, you will see that it is even easier since the data types in MySQL are very similar to IRIS. That is why we will not need to create transformation rules in the columns.

In GitHub it is possible to download a docker-compose project to build and run 2 databases:

Hey community! How are you doing?

I hope to find everyone well, and a happy 2022 to all of you!

Over the years, I've been working on a lot of different projects, and I've been able to find a lot of interesting data.

But, most of the time, the dataset that I used to work with was the customer data. When I started to join the contest in the past couple of years, I began to look for specific web datasets.

I've curated a few data by myself, but I was thinking, "This dataset is enough to help others?"

Hi Community,

We are pleased to invite all the developers to the upcoming InterSystems Datasets Contest Kick-off Webinar! The topic of this webinar is dedicated to the Datasets contest.

In this webinar, we’ll do a quick tour of the new LOAD DATA feature, also chime in on packaging global data or file data with ZPM, and run a data-generation script as part of a method in the zpm install.

As always, our experts will answer the questions on how to develop, build, and deploy datasets using InterSystems IRIS.

Date & Time: Tuesday, December 28 – 10:00 AM EDT

Speakers:
🗣 @Benjamin De Boe, Product Manager, InterSystems
🗣 @Evgeny Shvarov, InterSystems Developer Ecosystem Manager

The capacity of taking numerous records every second while also facilitating real-time queries simultaneously in real time is called Hybrid Transactional Analytical Processing (HTAP). It is also called Transactional analytics or Transanalytics or Translytics and is a very useful element in scenarios where there is constant flow of real time data coming from IIOT sensors or data on fluctuations in stock market, and supporting the need for querying these data sets in real-time or near real-time.

This is the fourth part of the series of articles on migrating from the main databases on the market to InterSystems IRIS. In this part, the procedures for migrating from Microsoft SQL Server will be detailed. As described in previous articles, there are currently a few options to do the migration, but the two most popular options include the use of DBeaver (https://openexchange.intersystems.com/package/DBeaver) or SQLGateway.

Hey Developers,

Let the voting week begin! It's time to cast your votes for the best applications in the Datasets Contest!

How to vote? Details below.

Transition and transfer from Caché to Iris databas. I have a question about import-export from Caché to Iris. Someone will tell you how to do this with a regular one, i.e. using standard procedures from Caché itself or Iris? I am asking in connection with the planned transition from Caché to the new IRIS DBMS.

Hi developers!

Sometimes we need to test this or that library, framework, or function vs some dataset. And often we want to deal with some meaningful data.

Recently I added two very simple but meaningful datasets that could be installed with one line.

Titanic Dataset

Application

Contains 800+ records about passengers from the famous cruise liner. The dataset could be installed with:

zpm "install dataset-titanic"

This installs one class dc.data.Titanic with 800+ records.

Countries dataset

Application

The dataset contains data about 167 countries such as population, surface, capital, the average life expectancy. The dataset could be installed as:

zpm "install dataset-countries"

This installs one class dc.data.Countries and the global with data.

Sometimes you need quickly and easily import data into IRIS. For this, an IRIS import manager has been developed.

This application allows you to import JSON data and also provides a really simple interface for transferring data from MongoDB collections to IRIS globals. It has never been so easy.

Let's look at examples.

Import JSON

Hi contestants!

We've introduced a set of bonuses for the projects for the Datasets Contest!

Here are the projects that scored it:

I need to generate a DDL file from a .cls class that already exists, the idea is to create a mirror table in SQL. Is it possible to do this export or do I need to do the CREATE TABLE manually?
