Introduction to Amazon’s SimpleDB. Amazon’s SimpleDB is a NoSql datastore with a whole lot of no: no sql, no datatypes (except utf-8 strings), no transactions, no joins, no indexes, no schema, no administration, and no cost for minimal usage.
But when you google it, you find Amazon’s docs, a lot of bold predictions about it from 2007 and 2008… and not much else. SimpleDB seems like an interesting solution in search of a problem, but its ease of use and lack of administration effort make it worth at least checking out. SimpleDB (and Amazon’s other web services offerings) can be accessed through a number of different APIs. For java, they have an eclipse plugin. Distributed Database Systems. In today’s web-enabled world, the use of Database Management Systems (DBMS) is extremely common and becoming even more necessary as each day passes.
In most cases, the choice is your typical RDBMS such as MySQL, PostreSQL, SQLite or SQL Server. Some enterprise-level systems choose larger solutions such as Oracle. As a company grows, it becomes a much bigger pain and seemingly less logical to maintain data in this manner.
