Abstract: A method for accessing information in a replicated database may include receiving a request for information in a database. The request may be associated with a table in the database. The table may include a plurality of identifiers each identifying a portion of the information in the table. The method may also include executing a logical structure associated with the table to produce a logical view of the table. The logical view may contain at least a portion of the information from the table, without containing the identifiers. The method may further include identifying the requested information in the logical view, and communicating the identified requested information in the logical view.

Abstract: A method for multi-site clustering in a network includes receiving a domain name from a client at a first domain name server, and identifying a first network address and a second network address associated with the domain name. The first network address is associated with a first site that includes a load balancer coupled to a plurality of web servers, and the second network address is associated with a second site that includes a second domain name server. The method also includes determining whether the first site is available to serve the client, and determining whether the second site is available to serve the client. The method further includes communicating the first network address followed by the second network address to the client based at least partially on a determination that the first site and the second site are available, and communicating the second network address to the client based at least partially on a determination that the first site is not available.
