I've been trying to find out more about Encirq and DeviceSQL for years. They have a very agressive marketing organization that plays fast and loose with the facts. But other than this, I haven't been able to learn much. Various web searches turn up nothing that isn't either written directly by Encirq or at least ghost-written by Encirq. I have never seen an independent 3rd-party evaluation of their product. If anybody is really using it, they have choosen not to blog about it. DeviceSQL is very different from SQLite. It is not a general-purpose SQL database engine. From what I understand, you enter SQL on your workstation. DeviceSQL then generates C-code that implements that SQL. Then you compile the C-code on your device. If you database schema changes, you have to regenerate the code and recompile your application. BTW, Encirq used to purchase Google ads claiming that DeviceSQL was 20x faster than SQLite. I don't know why they reduced that claim to 5x. -- D.
