Abstract
A system and method for storing data representing a multidimensional entity using corresponding dimensions for the data, storing a further dimension for the data, the further dimension being a modification timestamp indicating a time when the data was modified, receiving a request for the data representing the multi-dimensional entity, the request including a request timestamp indicating a further time when a previous request for the data representing the multi-dimensional entity was received and transmitting the data only when the modification timestamp is later than the request timestamp.
Claims18
A method, comprising:
- storing data representing a multidimensional entity using corresponding dimensions for the data, one of the dimensions being a modification timestamp indicating a time when the data was most recently modified;
- receiving a request for the data representing the multi-dimensional entity, the request including a request timestamp indicating a further time when a most recent previous request for the data representing the multi-dimensional entity was made;
- and
- transmitting the data only when the modification timestamp is more recent than the request timestamp.
A system, comprising:
- a memory to store data representing a multidimensional entity using corresponding dimensions for the data, a further dimension for the data, the further dimension being a modification timestamp indicating a time when the data was most recently modified and a set of instructions;
- and
- a processor executing the instructions to perform a method, comprising,
- receiving a request for the data representing the multi-dimensional entity, the request including a request timestamp indicating a further time when a most recent previous request for the data representing the multi-dimensional entity was most recently made, and
- transmitting the data only when the modification timestamp is more recent than the request timestamp.
A method, comprising:
- sending a current request for multidimensional data, the request including a request timestamp, wherein the request timestamp includes one of a null value request timestamp when the current request is an initial request for the multidimensional data and a time value of a most recent previous request when the current request is a subsequent request for the multidimensional data;
- receiving a response to the current request, wherein the response is a function of the request timestamp;
- storing the multidimensional data in a cache;
- applying a current timestamp to the multidimensional data, the current timestamp having a time value corresponding to the current request;
- and
- displaying the multidimensional data to a user.
