What we generally refer to as the report or report object is technically referred to as an RDLC Report. The RDLC Report is the information describing the logic to be followed when processing the data (the data model), as well as the output layout designed with Visual Studio Report Designer. RDLC Reports are stored in the NAV database.
We will use the term "report" whether we mean the output, the description, or the object. Reports share some attributes with pages including aspects of the designer, features of various controls, some triggers, and even some of the properties. Where those parallels exist, we should take notice of them. The consistency of any toolset, including NAV, makes it easier to learn and to use.
