Difference between build and deploy?

Question

What is the difference between a build and deploy and re-deploy? What should be done when you just have some

Answer 1

Watch this deploying process:

------ Build started: Project: AdventureWorks, Configuration: Release ------
Skipping 'belyaev_db.rds'. Item is up to date.
Skipping 'Sales Rep.rdl'. Item is up to date.
Skipping 'Top_10.rsd'. Item is up to date.
Build complete -- 0 errors, 0 warnings

------ Deploy started: Project: AdventureWorks, Configuration: Release ------
Deploying to http://...
Deploying data source '/Data Sources/belyaev_db'.
Warning : ...
Deploying data set '/Datasets/Top_10'.
Warning : ...
Error ...
Deploy complete -- 1 errors, 2 warnings
========== Build: 1 succeeded or up-to-date, 0 failed, 0 skipped ==========
========== Deploy: 0 succeeded, 1 failed, 0 skipped ==========

In this case I have some issues but as you can see - first step is in building - verification data sources and reports and only after that - deploying.
