Some of database tables I worked with had over 100 columns.

  I don't think you need to map all of them to a single object - projections work well here. There are very few cases where you need to work simultaneously on that many columns.

    I can't imagine other way of dealing with database rather than using a single class per table. Projections are a way to optimize some niche queries which are too slow otherwise.

      A 100 column table will be slow either way.
