It includes many tools and software for data warehousing, data mining, and data analysis with a graphical, easy-to-use, no-code, and user-friendly GUI environment. Easy, isn’t it?

A Brief History Of Pentaho Data Integration:

PDI is also referred to as Kettle.

Kettle was a powerful ETL tool based on Java. Kettle itself represents its meaning, KETTLE stands for Kettle Extraction Transformation Transport Load Environment. Matt Casters, an independent BI consultant developed Kettle and it was open-sourced in 2005.

It was acquired by Pentaho in 2006 and the name was changed to ‘Pentaho Data Integration.’

There are many components such as Spoon, Pan, Kitchen, Carte – all these names are culinary metaphors given to these offerings.

Let’s learn how these components make PDI a perfect solution for data integration jobs.

Here Are Key Components Of Pentaho Data Integration:

  • Spoon:

Spoon is a desktop application that allows developers to create workflows – transformations and jobs. Transformations refer to sourcing, processing, and loading the data. Jobs are used to coordinating resources, dependencies, and execution of ETL activities. Transformations and jobs are two basic file types in data integration.

  • Pan:

Pan is the PDI command-line tool for executing transformations. Transformations can be from a PDI repository or a local file.

  • Kitchen:

It is also a command-line tool for executing the jobs developed through Spoon (PDI Client).

  • Carte:

Carte is a simple web server that allows executing transformations and jobs by setting-up a remote environment.

The most important component of PDI is Spoon. All these components are widely used for smooth, end-to-end, and hassle-free data integration.

Now, let’s learn what makes PDI popular for data integration jobs. To understand this, we have to talk about key data integration challenges faced by the organizations.

Data Integration Challenges Your Business May Face:

  • Data Is Everywhere:

No one can ignore this fact. To get the most out of data, you first need to identify sources and that’s where a problem may occur. Data is everywhere and consolidate it all in one place becomes a challenge for most organizations. Along with that, data accuracy, timeliness, and relevancy are important factors for data integration.

  • Inconsistency of Data:

Inconsistency in data formats may take a lot of time for developers and by the time developers manually format, refine, validate, and correct, data might have lost its value. Data transformation tools make this easier like never before and make data actionable by identifying base language and automatically making changes.

  • Timeliness of Data:

Sometimes you might need real-time data to meet specific demands. If your system or solution can’t perform this effectively, you may end up losing opportunities related to it. This challenge becomes more complex when there are large datasets and sources. Slow performance may also become an issue when there are large datasets and multiple data sources.

  • Poor Quality:

Not all data is used in decision-making. Due to an ever-increasing amount of data, it often happens that more than half of the data goes unused for analytics. Quality of data must be managed to take accurate business decisions and implement data-driven strategies. Data quality management requires constant monitoring, smart solutions, and a proactive approach.

Apart from this, lack of approach to data integration and choice of wrong software may become troublesome for the organizations.

What Are The Advantages Of Pentaho Data Integration And Why PDI Is An Answer To Every Data Integration Challenge?

Here are some of the key advantages of PDI, making it a popular tool in the data analytics market.

  • Metadata-Driven Approach:

Pentaho uses a metadata-driven approach that allows users to specify what to do exactly and not how to do it. This allows developers to choose from a wide range of predefined plugins and widgets and tell them what to do as per requirements.

This makes developers’ jobs easier and offers more flexibility in creating data manipulation jobs.

  • Easy Learning Curve:

PDI offers intuitive and drag-and-drop interfaces, making it very easy to learn and use. It saves a lot of time with prebuilt components to rapidly onboard data from various sources. Developers can also add their own custom extensions easily and quickly with a plug-in architecture. It lets developers create data pipelines in minutes by using Spoon (PDI Client) which is a no-code GUI and editor for running jobs and transformations.

  • Large Data Volumes? No Problem:

Pentaho’s architecture is capable to handle extremely large data sets. PDI is used for enterprise-level data integration, blending, and data cleansing. It is necessary to reduce the overhead of data integration and blending so that data-driven enterprises can focus on analyzing data to drive decisions. Pentaho simplifies the creation of data pipelines and processes data at scale.

  • Flexibility:

Data from any source in any environment – this sums up the capability of PDI in one sentence. PDI is an extremely flexible tool that offers a range of features that include integration, ingest, and preparing of data from any source. It offers broad connectivity to a variety of data sources that include structured, semi-structured, and unstructured data whether they are in the cloud or on-premise.

Cross-platform support, use of Java, and the ability to deal with large datasets are some of the key benefits PDI offers.

  • Performance:

Gartner recognized Hitachi Vantara for its ability to complete vision in the 2020 Magic Quadrant for Data Integration Tools. PDI delivers exceptional performance even when it comes to processing a large amount of data. Using PDI, organizations can gain real insights from data with less complexity and time. It is a Lumada DataOps Suite product that enables organizations to make good use of data, simplifying data management across the organization without any complexity and at speed.

Let’s learn about some common use cases of PDI:
