Rob Tweed

The document outlines various NoSQL database models including key/value, columnar, graph, and document databases, emphasizing their flexibility and capability. It illustrates these models using Global Storage with examples such as telephone records, linked lists, and graph relations. It also notes that additional models like relational and object databases are supported by Caché, along with native XML databases.
