Big data

Carman dissertation focuses on algorithm codes over shared databases

Congratulations to Preston Carman, WWU assistant professor of computer science, on completing his doctorate in computer science from the University of California, Riverside.

Carman completed his dissertation, “Interval Joins for Big Data,” in September 2020. His research included reviewing five existing computer algorithms that had only been tested as a proof of concept and not implemented in a real database. He searched for the most efficient algorithm that joined intervals on big data using many machines.

Carman’s goal was to complete a project that would allow others to benefit from what he learned. His performance analysis allowed him to share his new algorithm implementation with an open-source database where it can continue to be used.

“I’m proud that the code I wrote is actually being utilized in a real database system,” Carman said.
