dbslice - Flexible, Web-Based, Database-Driven Visualization

Recent developments to dbslice, an open-source tool for visualization of database-stored data are described. The data is accessed using a web client that allows the user to select the computational or experimental ‘Tasks’ of interest by interactively filtering based on the Task’s high-level description, or ‘Meta Data’. The user is then able to dynamically add plots of different types (point, line, contour, and three-dimensional surface) using data from the selected Tasks at particular locations, ‘Slices’, within the computational domain or experimental test. As well as the greater number of available plot types, dbslice now offers increased flexibility to interact with existing databases, interactive filtering of all plot types for more flexible and intuitive workflow, and the ability to capture, recall and share dbslice sessions using configuration data. Two Case Studies are provided to illustrate these improvements: a design study of 3-stage axial compressors, and a portal for real-time UK river level data.
