Time-related properties may be modeled independent of a base object. Rather than storing time properties with the object, they may be stored independently. A given object may be stored once, even if it has a recurrent time property. The description of a 'meeting,' for example, may be stored once. Each occurrence of that object over time may be stored in a 'timeslot' (object &#x3c;foo&#x3e; occurs at time 't' on day 'd'). If it is a recurring property, recurrence information may be stored independently. &#x201c;Exception&#x201d; information may be stored independently as well.

Modeling recurring events in a data store

A client is authenticated by a server receiving an initial request from the client at the beginning of a session. The server receiving the initial request generates an authentication token and returns the authentication token to the client in response to the client being authenticated. The user's credentials used to authenticate the client are stored in the authentication token along with other information. After receiving the authentication token from the server that generated the authentication token, the client passes the authentication token with each of the future requests to the pool of servers. Using the client to pass the transferrable authentication token, the servers share the user's identity/credentials in a decentralized manner. Any server from the shared pool of servers that receives a subsequent client request is able to decrypt the token and re-authenticate the user without having to prompt the client for authentication credentials again.

Multi-server authentication token data exchange

The relationships between physical data store schema, object model, and end-user property may be encoded in the source of the object model using attributes. Reflection may be used to build the table of those relationships so that changes to the relationships between those three layers can be easily and quickly made without impacting higher levels in the software stack.
