I recently started building an application using Squeak and Seaside and was hunting for a persistence scheme. I looked at postgres and mysql. I looked at some magma examples, minnestore, goods. I settled on just doing something quick and easy – sixx xml to disk. This way I can load everything on start up, work out of an in memory db, write changes to disk and in the event of a crash we’re covered. This scheme is not super robust and won’t scale past a single seaside image but it should be enough to get us through the proof of concept phase. I want it to last a year and take us to the point where we start turning a profit.
