Abstract: Several local databases may be linked together to form a large database. Each database may share a common type definition, but may contain only a portion of the large database. When a local database queries information from another database, the result may be stored locally using the type system. Across the entire database, items may be identified as their local or home database along with an identifier provided by that database. Cached information may be stored locally and may refer to the source for that information through the identifier. Once the cached information is present, queries that reference the record may be satisfied by the cached information. The cached information may be refreshed from the source database or may expire to avoid stale or changed data in the cache.

Abstract: Technologies are described herein for applying type projection queries to instance space graphs. Through the utilization of the technologies and concepts presented herein, a type projection may be used to describe the hierarchy of instance types connected by relationships within an instance space graph. A type projection query based on the type projection may be dynamically generated to query instances and relationships within the instance store. Filter criteria for the query can be expressed using a path notation. Results from of the type projection query may be provided as graphs of instances and relationships which are subgraphs of the queried instance space graph. Programmatic traversal of the resultant subgraph can navigate to each instance node within the result space.

Abstract: A remote server managing multiple client computers at a customer site communicates with a server at a service provider site. A proxy gateway at the remote server allows communications through a network to the server at the service provider site. Remote monitoring of the multiple client computers may be performed at the server at the service provider site through a central monitoring console.
