Any insight, on what salesforc, zoho, googleapps, facebook uses, would be great we are looking for some concrete advise, so we can decide at the design stage.

Dear EE Members,

I am exploring the possibility of doing a SaaS based computing platform similar to those of salesforce.com, zoho, and the likes,

What we need to decide is which database platform to use i.e. MySQL, MS-SQL, Oracle, or any other format,

Any insight, on what salesforc, zoho, googleapps, facebook uses, would be great we are looking for some concrete advise, so we can decide at the design stage.

Database Engine for SaaS

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Databases

Cloud computing, also known as on-demand computing, is a kind of Internet-based computing where shared resources and information are provided to computers and other devices. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers, relying on sharing of resources to achieve coherence and economies of scale.

Cloud Computing

Amazon Web Services (AWS), is a collection of remote computing services, also called web services, that make up a cloud-computing platform  operated from 11 geographical regions across the world. The most central and well-known of these services include Amazon Elastic Compute Cloud, also known as "EC2", and Amazon Simple Storage Service, also known as "S3". Other services include Elastic MapReduce (EMR), Route 53 (a DNS web service),  provides a highly available and scalable Domain Name System (DNS) web service, Virtual Private Cloud (VPC), storage, database, deployment and application services.

A NoSQL database provides a mechanism for storage and retrieval of data which is modeled in means other than the tabular relations used in relational databases. Motivations for this approach include: simplicity of design, simpler "horizontal" scaling to clusters of machines and finer control over availability. The data structures used by NoSQL databases (e.g. key-value, wide column, graph, or document) are specified from those used by default in relational databases, making some operations faster in NoSQL. Sometimes the data structures used by NoSQL databases are also viewed as "more flexible" than relational database tables.
