The Problem In the current technology world, SOA is becoming more and more common and issues related to concurrency is inevitable if the system design is not proper. With increasing concurrent user requests, the system should be capable of establishing multiple database connections without any deadlock or race condition. Solution/The Design guidelines Some design guidelines I recommend and follow while architecting a system that should be able to establish simultaneous database connections. 1.

You can experiment with different distance from the subject with different apertures. These all pics are Straight Out of Camera. XQ2 is really good for the landscape as well. It cannot deliver ultra wide-angle shots, but goo...
