Multicenter data acquisition made easy

BACKGROUND The process for data collection in multicenter trials may be troublesome and expensive. We report our experience with the spreadsheet function in Googledocs for this purpose. METHODS In Googledocs the data manager creates a form similar to the paper case record form, which will function as a decentral data entry module. When the forms are submitted, they are presented in a spreadsh...

Data Exploration Made Easy

A comprehensive graphical analysis approach to perform data exploration utilizing the latest capabilities available in SAS systems are presented here. This ® practical approach integrates graphical analysis tools available in SAS systems and provides step-wise instructions to perform data exploration quickly without writing SAS program statements or using menu interface by running the SAS macro...

Concurrent Programming Made Easy

The task of programming concurrent systems is substantially more difficult than the task of programming sequential systems with respect to both correctness and efficiency. In this paper we describe a constraint-based methodology for writing concurrent applications. A system is modeled as: (a) a set of processes containing a sequence of “markers” denoting the processes points of interest; and (b...

Distributed CQL Made Easy

This talk is about making it easy to implement a distributed CQL. CQL is a continuous query language that extends SQL with a notion of windows over infinite streams of data. Programmers like using CQL, because its syntax is already familiar to them from their experience with other database-backed applications. CQL was originally designed to target a single node implementation of the Stanford St...
