R-IVEware (Remote usage of IVEware, Version 0.1 ) There are many situations where the data sets reside in one location and the analyst in a different location who wants to perform the analysis of data but cannot download data to his/her location and /or they do not have SAS installed on their local machine. These could be people working from home, in different buildings or living in different city or even country. There are several reasons for data to remain in one central server/location: To avoid duplication of data sets at various locations, confidentiality and privacy concerns and data use/software licensing restrictions.
The R-IVEware, is the modification of IVEware package that allows analyst from any location to submit the commands via web interface to a “web server”, the analysis is then carried out by the “compute server” and the the analysis output is then e-mailed to the user. The web server manages the login, provide access to relevant information for the user to develop the IVEware script and submit the analysis request. The analysis is then carried out by the compute server and the result is sent back to the user via e-mail associated with the particular login. The user in the remote location does not need any software installed and can use any standard web interface such as Internet Explorer, Firefox, Safari, Google Chrome etc. The webserver and compute server can be in the same machine or in two different machines. The R-IVEware requires the standard Linux operating system on both compute and web servers. The computer server should have SAS installed. The installation of R-IVEware requires administrative privileges and considerable knowledge of the computing architecture where the R-IVEware will be installed. The IT person manages the login access as well as tailor the access of the data sets to each user. For example, the login may be time limited and not all data sets may accessed by each user. Thus, R-IVEware provides considerable flexibility in carrying out the analysis of data. With Describe, Impute, Regress and Sasmod modules, R-IVEware can be used to analyze data from observational and experimental studies and from sample surveys.
