Abstract: A device includes: a first portion configured to be grasped by the hand of the user, and a second portion defining a reservoir containing a control material, wherein the control material contains a target analyte in a known or predetermined concentration. A method of verifying the accuracy of an analyte monitoring device includes receiving a fluid sample, identifying the fluid sample as a control solution, and analyzing the fluid sample.

Abstract: Exemplary embodiments are disclosed for a method and system of parameterizing data aggregation performed by a data integrator executing on a computer. Aspects of the exemplary embodiment include in response to receiving business rules input from an end-user through a graphical user interface, storing the business rules as aggregation parameters in a repository external to the data integrator; reading the aggregation parameters, the aggregation parameters specifying the source table of transaction data, a target table for storing aggregation results, and summarization requirements specifying aggregation actions to be performed on fields of at least one of the source table in the target table; and aggregating the transaction data based on the summarization requirements, including grouping and summing transaction values, whereby the aggregation parameters enable aggregation of the transaction data from the source table to the target table without modifying code comprising the data integrator.
