The Spanish Conference on Software Engineering and Databases (JISBD) is a research forum for researchers from Spain, Portugal and South America working on Software Engineering and databases. The Ibero-American community around these research areas finds in JISBD an annual meeting point where researchers can present, discuss and interchange their research works and ideas, and network. Over the course of more than 20 editions, JISBD has significantly contributed to consolidate the iberoamerican research communities working on Software Engineering and databases. In the XXIII edition, JISBD is organised into tracks, among which the track on Search Based Software Engineering (SBSE) will be held.
