I am not sure that not being able to Access data on a database is going to be the cause of bankruptcy unless the comapny in question has made some big mistakes! There could be some Problems whereby Trends normally analysed by a Data Warehouse would be missed that could result in Business operations being hindered but even that is avoidable.

I think maybe you should consider whether just the loss of a database is the central Focus or whether or not an effective Business continuity plan is in place. Normally, when Business continuity plans are effective, the Company in question can still operate just in a very restricted manner.

The summary for your Thesis should be "a Company without a disaster recovery objective or effective Business continuity plan is the Company that will go down in the Event of catastrphic dataloss".

All you Need to do now is fill in the gaps!
