This is why I built DataPlexer, and what I've learned using it in production.Sun, 01 Mar 2026 12:00:00 GMThttps://mgm.sh/of-dashcards-and-drill-down-mapshttps://mgm.sh/of-dashcards-and-drill-down-mapsIn the world of Data Visualization, Context is King.Thu, 23 Jul 2020 12:28:03 GMThttps://mgm.sh/qvd-segmentation-20-speeding-up-qvd-partitioning-by-up-to-5xhttps://mgm.sh/qvd-segmentation-20-speeding-up-qvd-partitioning-by-up-to-5xThis technique is typically used in Qlik Deployments that deal with large datasets, and allows us to split a large table into multiple QVD files.Mon, 30 Sep 2019 00:01:49 GMThttps://mgm.sh/video-incremental-data-extracts-with-qlik-using-delta-tags-and-qvd-segmentationhttps://mgm.sh/video-incremental-data-extracts-with-qlik-using-delta-tags-and-qvd-segmentationThe following 14-min video is taken from one of the lessons in my Lean Data Processing online courseMon, 27 May 2019 18:46:40 GMThttps://mgm.sh/enhancing-your-data-strategy-on-qlik-projects-with-the-lean-data-processing-paradigmhttps://mgm.sh/enhancing-your-data-strategy-on-qlik-projects-with-the-lean-data-processing-paradigmOn the importance of having a solid Data Strategy in conjunction with a good Analytics Strategy to build and support a robust Data PlatformTue, 21 May 2019 18:46:17 GMThttps://mgm.sh/delta-tags-a-new-mechanism-for-efficiently-keeping-track-of-incremental-reloads-in-qlikview-and-qlik-sensehttps://mgm.sh/delta-tags-a-new-mechanism-for-efficiently-keeping-track-of-incremental-reloads-in-qlikview-and-qlik-senseWhen working with large datasets in QlikView and Qlik Sense, it's important to ensure the backend data processing jobs (Extracts and Transforms) perform efficiently, by following best practices to reduce execution time and keep resource usage at a minimum.
