Not the only crock of doo-dah they bought from IBM ...
I would wish HCL on a worst enemy, but not on nice people!
Also had the misfortune to deal with them quite closely over two years on UrbanCode, another product they acquired from IBM along with Notes, Domino etc.
It is fair to say they knew nothing about basic database design and relational principles, but they were very good at dragging their knuckles on the floor, missing SLAs and holding management meetings. HCL were unable to provide any technical skill, support or experience for certain supported platforms and were largely incapable of engaging technical support from outside. The end customer was just left to flounder, strung along with meaningless promises. I found HCL to be arrogant and unwilling to listen and learn.
Just personal experience, but in the sheer awfulness stakes they are still pipped to the post by TCS and IBM India.
