3. Certified Engineer Course OS/2 32bit OS from IBM In '94 competition to Win95 Presentation Manager > object oriented desktop > object usage Loyal user base Dead by now

4. Certified Engineer Course DataObject Logical object around FileObject > more than a plain content > copy, move, shadow, createFromTemplate Multiple files Factories > many implementations Document vs. Tool model > templates, missing save as

5. Certified Engineer Course DataLoader Factory > by mime type > by extension Context Actions > String actionsContext(); > read from a layer > regular swing actions Can have persistent state

6. Certified Engineer Course FileSystems vs. Loaders API One type vs. multiple types One file vs. group of files Raw data vs. operations on them A.java A.class B.properties B_ja.properties
