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.
