1. Amazon SimpleDB
The developers are enabled with highly available and flexible NoSQL column
database called Amazon SimpleDB for storing and querying structured data items
through Web services requests. High availability and flexibility are offered by the
design along with Amazon SimpleDB as it reduces the database administration
burden.
Database as a service (DbaaS) offering is hosted by Amazon SimpleDB. An account
can be set up by Amazon SimpleDB for use for storing and querying data items with
the help of Web Services requests.
• Amazon SimpleDB Offerings
Basic (included), which offers 24 x7 customers service.
Best practice guidance and an assured response time to incidents which is less than
12 hours are included by the developer.
API support and assured response time to incidents which is less than one hour are
included in the business.
Direct access to a technical account manager is included by Enterprise infrastructure
event management and assured response of incidents which is less than 15 minutes.
• Amazon SimpleDB Features
For creating and storing multiple data sets, a simple Web Services interface is offered
by Amazon SimpleDB by querying your data and returning the results.
Here are few highlights:
A subscriber is any application, software or script for making a call to the Amazon
SimpleDB service. Each subscriber is identified by the AWS Access Key ID for
billing and metering purposes.
A single Web service API call also called Amazon Simple DB Request and it's
associated data that the subscriber sends to the Amazon SimpleDB service to perform
more than one operations.
Any results returned from the Amazon SimpleDB service is none other than Amazon
SimpleDB Response to the subscriber after processing the request. Authentication
success and failure are handled by the AWS platform.

2. For running a production database, Amazon SimpleDB makes you reduce the work
needed to run a production database. For entering the information it is the best and
low-touch data store about conditions or events, status updates, recurring activities,
work flow processes and application states. These data logs are meant to be set and
forgotten by Amazon SimpleDB and use them for things like tracking or monitoring,
trend analysis, metering, auditing and archival or meeting requirements.
Online gaming is supported by Amazon SimpleDB apart from that. There are a high
availability and scalability with a database which is free of administration for user
and game data especially for developers of online games on any platform.
If there is a need to do any data comparison like GROUP BY or aggregate data or
something more than simple storage and retrieval, Amazon SimpleDB is not about to
work as well.
• Amazon SimpleDB data types
Text Strings is the only way treated by all the data. You can organize your structured
data by using Amazon SimpleDB in domains and you feed data into it and get data or
run queries. Items described by attribute name-value pairs are present in the domain.
Various data stored in Amazon SimpleDB is not indexed manually for fast and
accurate retrieval.
• Getting started with Amazon SimpleDB
It is a known fact that Amazon SimpleDB is not an open source and there is no
licensed software for installing on a local server. Rather, you need to pay for what
you use and there is no minimum fee required. The price depends on the region to
establish your Amazon SimpleDB domain(s).
