Project Management

A MIDAS project consists of the following resources:

• Primary Dataset - Source data loaded from CSV or other files
• Derived Dataset - Data generated by SQL queries or transformations
• Model - Fitted models such as GLM
• Report - Collections of graphs and statistical results

These resources have dependencies on each other. For example, a Derived Dataset depends on its parent Primary Dataset, and a Model depends on the dataset used for fitting. When you update an upstream dataset, downstream Derived Datasets are recomputed on the next access, and dependent Models are automatically re-estimated. See Datasets for details.

Project Management Tabs

Three dedicated tabs are available for managing your project. All can be opened from the File menu or the command palette (Cmd/Ctrl+P).

• Project Overview - View and manage resources (rename, delete, view metadata, etc.)
• Project Lineage - Visualize dependencies between resources as a graph
• Compare Project - Compare with an MDS file (the MIDAS project file format, extension .mds) to view differences. The File menu shows this as Compare with File...

Dataset Specifications

Deleting a dataset also deletes the Derived Datasets and Models that depend on it. For details on cascade deletion, lazy evaluation and caching, Materialized View, and automatic SQL updates on rename, see the Datasets page.
