1. A computerized information system for capturing, aggregating, and visualizing model structural data representing an information technology architecture, the system comprising: storage medium at least one abstracted data model; a graphical user interface generation engine; a visualization engine; a scenario management engine configured to simulate, visualize and evaluate changes in the architecture; at least one data capture engine configured to capture and aggregate data stored on the storage medium according to a structured, hierarchical model which is adapted to provide a structured, hierarchical view of a model structure and to build a basic frame for analysis and visualization, the model being either a standardized model or a customer specific model; and a display engine configured to generate a plurality of different displays of the captured data according to the structured hierarchical model; wherein the structured, hierarchical model comprises tables of related records, which are associated by either strong links or loose links, wherein the strong links make use of Row-IDs, and are adapted to provide for every record having a foreign key relationship to a primary key of a record in another table, and wherein the loose links make use of a row's Row-ID, and are adapted to provide for establishing a foreign key relationship to another table, wherein the models and their components are strongly coupled together by at least one strong link, and relationships between models are loosely coupled by one or more loose links adapted to allow that end points of the respective relationship are moveable within a model or are removable without forcing the relationship to be removed as well, wherein a generic representation of a model is represented by strong links between core model tables and graphical representation tables.
