An interesting aspect of a non-relational database such as NoSQL is scalability. NoSQL uses the BASE system (basically available, soft-state, eventually consistent). Non-relational databases forgo the table form of rows and columns relational databases use in favor of specialized frameworks to sto...
Attachments and database design rules By default, each field in a relational database contains only one piece of data. For example, if an address field contained more than one address, finding addresses would be difficult, if not impossible. So at first glance, atta...
