  1. Context … for projects and MyDB Kapteyn Astronomical Institute, Wednesday, 19 April 2006

  2. Context • Handling large amounts of data • Work together • Work in a consistent way • Experiment with source code • Know what data and code was used • Keep data private • Make data public • Throw away data

  3. Context • Organize in Projects, that have • A name and description • Users • Default privileges • Responsible - privileged – users • New objects are automatically part of the currently active context • Tools to safely delete or publish data • Be aware of dependencies for history tracking

  4. Setting and getting projects from astro.database.Context import context context.set_project('WORKSHOP2005') context.set_project('OCAM ILT') context.get_projects() context.get_current_project().name CALL AWOPER.AWSECURITY.SET_PROJECT('OCAM ILT')

  5. Migrating MyDB to other Project • Everything Toolbox/dbmigrateall.py AWMJACKSON KIDS • Single object, including dependencies sl = SourceList.name.like('*TEST*')[0] context.migrate(sl, 'VESUVIO')

  6. Deleting MyDB • Delete ALL objects that belong to MyDB project Toolbox/dbdeleteall.py AWMJACKSON • Includes files, which take up most space • No dependency check required

  7. Projects • Like MyDB, but for more users. • Delete all data that is private to KIDS Toolbox/dbdeleteall.py KIDS • Making data public, i.e. update privileges context.update_privileges(obj, 3)
