A computer implemented rating system for rating a company using at least one non-economic factor stored in a database populated with hierarchical data and metadata. The system displays at least a portion of the hierarchical data and a formula that generates a sustainability score, the sustainability score defining a rating of the company incorporating the at least one non-economic factor. The user can input at weightings into the system which associates each weighting with a respective non-economic factor. A processor computes the sustainability score using the formula by mathematically applying each associated user-input weighting to the respective non-economic factor. The system displays the sustainability score, and, in response to a user interaction, displays at least a portion of the hierarchical data including the metadata. The hierarchical data can include a second level of data which is used to compute the first level by applying weightings in a formula.
