Reviewing Concepts

Begin the tutorial by reading a description of the sample project, and concepts applied in it.

• The Sample Project
  The PortfolioValuation project that you build in this tutorial applies current prices to a portfolio of investments to compute the value of each investment and of the portfolio. It uses simple queries to aggregate and join data from two input windows.
• Schema Discovery Using Input Adapters
  In the tutorial you use the schema discovery feature to discover an external schema and create a CCL schema based on the format of the data from the datasource connected to an adapter.
• Simple Queries
  Accomplish most common querying tasks using a set of simple queries available in the Visual editor: filter, aggregate, join, compute, union, and pattern.
