The NCBI Genome Workbench is an integrated application for viewing and analyzing sequence data. With the Workbench, you can view data in publically available sequence databases at NCBI, and mix this data with your own private data.
A growing set of online tutorials to help you use the Workbench is available on NCBI's YouTube Channel.
