Database Journal Club is a public community for Database Research Lovers. Post papers of your interest and share what you thought. Adding a short summary of the paper is always appreciated, but it’s not mandatory for saving your time. You can use English, Japanese, or any other languages for the posts because we can use Google translate for multilingual communication. If you find a paper that can be a good candidate for on-site (off-line) reading groups, post it with`TO READ` tag. If you find some interesting article, clap (+1) this so that we can pick a good candidate paper to read in a democratic manner. Enjoy science of database designs through reading papers, and have wonderful discussions with enthusiastic members!
