Extract-Transform-Load (ETL) tools have provided organizations with the ability to build and maintain workflows (consisting of graphs of data transformation tasks) that can process the flood of digital age data. Currently, however, the specification of ETL workflows is largely manual, human time intensive, and error prone. As requirements become(More)
This paper describes the workflow specification problem, how workflows are specified today, requirements for improved workflow specification, and begins to sketch a new domain-specific modeling language (DSML) approach for specifying intent that can be used to constructively generate a complete workflow meeting a collection of intent requirements. This is(More)
Data file layout inference refers to the problem of identifying the organizational characteristics associated with a structured text file, where every record in a text file shares the same structural properties. These properties include: character encoding, record length, field length (indicated by delimiting characters or fixed length), field position, and(More)
The scale of big data causes the compositions of extract-transform-load (ETL) workflows to grow increasingly complex. With the turnaround time for delivering solutions becoming a greater emphasis, stakeholders cannot continue to afford to wait the hundreds of hours it takes for domain experts to manually compose a workflow solution. This paper describes a(More)
Computers are getting smaller, cheaper, faster, with lower power requirements, more memory capacity, better connectivity, and are increasingly distributed. Accordingly, smartphones became more of a commodity worldwide, and the use of smartphones as a platform for ubiquitous computing is promising. Nevertheless, we still lack much of the architecture and(More)
