esProc

esProc SPL is a programming language that runs on the Java virtual machine and is designed for computing on structured data. It serves two roles: an interactive data analysis tool for working through datasets, and an embedded computing engine that Java applications can call to run data processing logic.

The repository topics place it among database, SQL, dataset and cluster computing tools, which suggests it targets the same kinds of jobs as SQL and scripting languages for reporting and batch processing. Its README is dominated by badge images and the project's documentation is hosted on a separate site, so this entry sticks to the repository description. The code is written in Java.

esProc is licensed under Apache-2.0 and runs on your own machines or servers. It suits Java developers and data engineers who want a specialized language for structured data computation that can be embedded in existing applications.
