Added another blog post about using data sources with the Talend Runtime.

In the previous post, we set up a database Data Source within the Talend Runtime. The Runtime is the actual component that opens the connection to the Database, and your Data Service uses this pool…

In the previous 4 posts, we installed and configured the Talend Runtime to be a SSL secured, system service. In this post, we're going to install and configure a database data source for use within a data service. Your Talend data service uses the connection that the Runtime holds open rather than the data service managing the connection directly. We're going to be connecting to a MS SQL Server in this example, but other data source connectors exist....

In the previous 3 parts, we downloaded, installed, configured the Talend Runtime as a System Service and then revised the configuration to be secure using a self-sign SSL certificate. In this part, we're going to remove the self-signed certificate and replace it with a CA certificate. You can either purchase a long term certificate or use one of a number of free short term certificate authorities....

In the previous two parts, we downloaded and installed the Talend Runtime then deployed it as a System Service. In this Part, we're going to address securing the Talend Runtime. We will be using a text editor (Notepad++ is my favourtite) and a tool to edit the Java Keystore used by the Talend Runtime (Keystore Explorer is the only Freeware tool that I've found that is easy to use)....

In Part 1 of this series, we performed the basic installation and verification of the Talend Runtime. In Part 2, we're going to continue the installation process and create a service to run the Talend Runtime automatically on startup. First of all, we're going start a Command Prompt in Administrator mode and change directory to where we installed the Talend Runtime, …...

New post, not done one in a while, on how to use a High Water Mark.

When acquiring data from a source to load into something like a data warehouse or as part of a data integration, a common practice is to use a High Water Mark (HWM) mechanism. An HWM is normally a …

A short discussion on splitting your dimensional data.

When designing a star schema, an important set of decisions you will need to make, is the number of and structure of the dimensions you’ll be creating or using. The two most commonly used dim…

Wrote this some time ago on Dimensional Data Quality.

When you’re populating your fact tables in any data warehouse, it’s normal and accepted that sometimes not all of your dimensional joins will succeed. Given that most data warehouses ar…

I hope everyone put their clocks back one hour last night.

How does your data warehouse deal with it?

As we enter into Autumn, the rather spikey issue of how to deal with the end of daylight saving hours crops up. I’ve never really come across a satisfactory and simple solution for how to represent...
