Incremental FDs

Build Status

Postgres

Tests are being run with embedded postgres and do not need any further configuration.

For regular database access (e.g. demos), a test database can be set up:

  • Make sure postgres is installed
  • psql -f countries.sql -U <user_name> -W -d <db_name>
    • <db_name> has to be an existing Postgres database (either create one or use "postgres", which already exists by default)
    • <user_name> is your postgres username ("postgres") by default
  • create a copy of "properties.default.xml" (in "../database/src/main/resources") named "properties.xml" and adjust the parameters as necessary

Code Cleanup

Cleaned repositories:

  • processor
  • data
  • algorithms
  • benchmarks-util

Documentation still needed:

  • processor.batch.source.*
  • data
  • benchmarks-util

Tests missing:

  • benchmarks-util

incremental-fds's Issues

Investigate Music brainz dataset

The Music brainz datasets provides a full dump and a complete edit history. Maybe we can create some useful data for testing our system from this dataset.

Support for deletes

Basic idea:
Save cropped list of violating value combinations for every fd's child nodes in the lattice. If delete occurs, check childrens list. Only validate, if element cannot be found in the list. If so, add generalizations.

  • annotate lattice nodes with list of violating value combinations
  • support addition of generalizations
  • prune validations as described above

Make Repository Public

Dear Developers,

I am writing this as an issue, because I don't have your current email addresses: Can we make this repository public?

Since our paper was successfully published, I got two requests for the code of DynFD. Up until now, I just shared the code via zip and email. It would though be much better to have it publicly available.

Many thanks!
Thorsten
