Salesforce has technologies underneath which enables administrators to stack complex process, streamline actions and can even start new configurations like drag and drop applications, objects and code.
Technology companies offer the platform for all your needs. Few examples of platforms are

There are few basics on the platform technologies which is built in the Force.com platform, and they are more mandatory to be understood.
Software multitenancy is used in Salesforce database. This means one single instance of software will be run on the server and multiple tenants are served in return. In general, tenant means a group of users who shares a common access with only appropriate privileges to the software.
Each and every Salesforce customer will be allotted a private section from the larger database. Since all the orgs shares the same technology it is easy to release upgrades, do the bug fixes to all the customers at the same time without any hassle.
The common examples of multi-tenant architecture are Google Apps, Gmail, eBay, Amazon, and Microsoft Office 365.
The advantage of multi-tenant architecture is that the cost would be low and the speed at which the customers can adopt a solution is much faster. When customers wanted to give a try before deploying Salesforce they can opt for a trial version to make sure it would fit their needs. There is no necessity to purchase Salesforce before even trying them. There is no reason for the upgrade unless you decide to serve more people.
Since Salesforce is frequently updated in the cloud no matter how long a customer has been with Salesforce, they go through the same process and will be using the latest functionalities. Salesforce is a highly secure platform, and new functionality can be deployed very easily.
Salesforce AppExchange is just like an App store where customers and the third party companies can market their configured solutions based on business problems. These applications can be browsed and installed by the Salesforce users to the Salesforce org. The Apps in the App store can include anything starting from analytics to account management to survey the applications better.
