DB_Schema

Hi, I have gotten back to DB_Schema development. This build on Wolframs DB_Structure idea and maybe the following code will become DB_Structure in the end. Of course this code hasn't been tested at all yet and is just the result of two short hacking sessions. http://backendmedia.com/DB_Schema/Objects.phps Explanation: Basically the idea is that there will be readers and writers. Readers will build up an object tree of database objects and writers will serialize an object tree. Readers can get their data from any sort of source: Database server, sql file, xml file (in various formats), proprietary formats etc. Writers in turn can serialize to all of the above sources. Database objects are databases, tables, fields, indexes, sequences etc. For each database object there will be a class that knows what objects are allowed to be nested within. How to compare itself with another instance etc. Therefore DB_Schema will consists of: Various reader classes Various writer classes Various database object classes And a core class that ties the reader and writer together People can customize the reader, writer and database object classes. In conjunction with the extensibility of MDB 2.x in regards to the datatype and manager method this means that you have a very powerful framework in which you can manage your schemas. regards, Lukas Smith smith@backendmedia.com _______________________________ BackendMedia www.backendmedia.com berlin@backendmedia.com Linn Zwoch Smith GbR Pariser Str. 44 D-10707 Berlin Tel +49 30 83 22 50 00 Fax +49 30 83 22 50 07
