Two points I found most interesting from this article:
1. The indexing of a database can speed up access to the information but slow down data maintenance. This is a dual-edged sword--we want the client to have fast access to the information provided in the database, but it costs money to maintain the databases, and if indexing requires more maintenance, then it seems indexing requires more thought than one would think.
2. Database replication. It is a simple concept, but one I hadn't really thought about: mulitple copies of a database could be running on different computers. Given the fragile state of computers, it certainly makes sense.
Database replication is a good idea. Although, the speed that technology advances, and computer companies eliminating operating systems, database replication could become out of date very quickly.
ReplyDeleteI had never thought about database replication either. As you say, it makes sense, though. I incessantly back up all of my files on either an external hard drive or via Gmail, and those are just personal files...
