NoSQL standouts: New databases for new applications: Cassandra, CouchDB, MongoDB, Redis, Riak, Neo4J, and FlockDB reinvent the data store.
From the post:
Was it just two or three years ago when choosing a database was easy? Those with a Cadillac budget bought Oracle, those in a Microsoft shop installed SQL Server, those with no budget chose MySQL. Everyone in between tried to figure out where they belonged.
Those days are gone forever. Everyone and his brother are coming out with their own open source project for storing information. In most cases, these projects are tossing aside many of the belts-and-suspenders protections that people expect from the classic databases. There are enough of them now that some joker started calling them NoSQL and claiming, perhaps tongue-in-cheek, that the acronym stood for Not Only SQL.
I remember reading somewhere that the #1 reason for firing sysadmins was failure to maintain proper backups. A RDBMS system isn’t a magic answer to data security and anyone who thinks so, is probably a former sysadmin at one or more locations. 😉
You need to read Jim Grey’s Transaction Processing: Concepts and Techniques if you want to design reliable systems. Or that is at least one of the works you need to read.
Do use the “print” option so you can read the article while avoiding most of the annoying distractions typical for this type of site.
Not detailed enough to be particularly useful. Actually I haven’t seen a comparison yet that was detailed enough to be really useful. I suppose in part because the approaches are different, would be hard compare apples with apples.
What might be useful would be to compare the use cases where each system claims to excel. Now that might be a continuum of interest to readers.
What do you think?
