What do you like best?
Fast data access due to hashing and the ability to model data as it really exists in real life due to being a 4 dimensional database by design. You can have multiple dictionary definitions for the same data fields to fit different situations.
What do you dislike?
Lack of recognition in the industry if potential customers are concerned about name recognition of the underlying technology rather than what the application can do for them.
Recommendations to others considering the product:
If you have not used D3 before, realize that you have to adjust your thinking to model data since you can use 3 or 4 dimensions instead of being limited to 2 dimensions that SQL databases have.
