KNIME Essentials

Overview of this book

KNIME is an open source data analytics, reporting, and integration platform, which allows you to analyze a small or large amount of data without having to reach out to programming languages like R. "KNIME Essentials" teaches you all you need to know to start processing your first data sets using KNIME. It covers topics like installation, data processing, and data visualization including the KNIME reporting features. Data processing forms a fundamental part of KNIME, and KNIME Essentials ensures that you are fully comfortable with this aspect of KNIME before showing you how to visualize this data and generate reports. "KNIME Essentials" guides you through the process of the installation of KNIME through to the generation of reports based on data. The main parts between these two phases are the data processing and the visualization. The KNIME variants of data analysis concepts are introduced, and after the configuration and installation description comes the data processing which has many options to convert or extend it. Visualization makes it easier to get an overview for parts of the data, while reporting offers a way to summarize them in a nice way.

In Report Design, there are many preferences; we will cover only a subset of them.

Within Report Design, the Preview subpage might be interesting, because you can customize how the preview should work, such as setting the locale, time zone, bidirectional orientation, using external browser, or enabling SVG charts. You can also disable the master page in previews. In its Data subpage, you can set bounds on data usage for previews. If you are bound by your machine running KNIME, you can also use a server to generate the preview of the reports. To do this, you have to specify the server in the Preview Server page in Report Design.
