Below are some significant features of SharePoint 2013,
SharePoint 2013 introduces a Cloud App Model that enables you to create apps. Apps for SharePoint are self-contained pieces of functionality that extend the capabilities of a SharePoint website. An app may include SharePoint components such as lists, workflows, and site pages, but it can also surface a remote web application and remote data in SharePoint. An app has few or no dependencies on any other software on the device or platform where it is installed, other than what is built into the platform. This characteristic enables apps to be installed simply and uninstalled cleanly. Apps have no custom code that runs on the SharePoint servers. Instead, all custom logic moves “up” to the cloud or “down” to client computers. Additionally, SharePoint 2013 introduces an innovative delivery model for apps for SharePoint that includes components like the SharePoint Store and the App Catalog.
New and improved social and collaboration features make it easy for users to communicate and to stay engaged and informed. The improved My Site social feed helps users keep up to date with the people and content that they care about. The newCommunity Site feature provides a rich community experience that lets users easily find and share information and find people who have similar interests.
Search functionality in SharePoint 2013 includes several enhancements, custom content processing with the Content Enrichment web service, and a new framework for presenting search result types. Additionally, there have been significant enhancements made to the keyword query language (KQL).

Business Connectivity Services (BCS):
Business Connectivity Services (BCS) enables SharePoint to access data from external data systems such as SAP, ERP, and CRM, in addition to other data-driven applications that are exposed through WCF services or OData endpoints. BCS in SharePoint 2013 has been improved and enhanced in many ways, including OData connectivity, external events, external data in apps, filtering and sorting, support for REST, and others.
SharePoint Server 2013 includes several services for working with data in your SharePoint sites.

For converting files and streams to other formats, SharePoint Server 2013 has Word Automation Services and PowerPoint Automation Services (a new feature for SharePoint). SharePoint also provides data analysis tools, like PerformancePoint Services and Visio Services, that enable business intelligence, and powerful new features in Excel Services.
