This website provides access to the NASA IV&V Facility Metrics Data Program repository. The repository contains software metrics and the associated error data at the function/method level for NASA software development projects. The data is neither representative of nor generated by IV&V analysis.

The repository metrics include:

• McCabe Software Metrics
• Halstead Metrics
• Line of Code Metrics
• Error metrics derived from the association between errors and functions/modules
• Requirement Metrics

The association between the error data and metrics data in the repository provides the opportunity for users to investigate the relationship of metrics or combinations of metrics to the software.

The repository data is available at no cost.

The Metrics Data Program Data Repository is a database that stores problem data, product data and metrics data.

The primary goal of the repository is to provide project non-specific data to the software community.

The data that is made available to general users has been sanitized and authorized for publication through the MDP website by officials representing the projects from which the data has originated. The database uses unique numeric identifiers to describe individual error records and product entries. Projects are given a pseudo-name and can also be referred to with unique numeric identifiers. The level of abstraction allows data associations to be made without having to reveal specific information about the originating data.

The database is available to the software community through the Metrics Data Program website.
