A project contains a model, namespaces, packages, data sources, and related information for maintaining and sharing model information. A single project can span many data sources or tables.
A model is the set of related dimensions, query subjects, and other objects required for one or more related reporting applications.
The Framework Manager model is a metadata layer that adds value to a data source in several ways. Most importantly, it provides a business view of the information in the source data to simplify building reports, analyses, and queries.
A namespace uniquely identifies query items, dimensions, query subjects, and other objects. You import different databases into separate namespaces to avoid duplicate names.
A package is a subset of the dimensions, query subjects, and other objects defined in the project. A package is what is actually published to the Cognos 8 server, and it is used to create reports, analyses,and ad hoc queries.
A dimension is a broad grouping of data about a major aspect of a business, such as products, dates, or markets. The types of dimensions that you can work with in Framework Manager are regular dimensions and measure dimensions. In SAP BW, measure dimensions are called key figures.
A query subject is a set of query items that have an inherent relationship.
In most cases, query subjects behave like tables. Query subjects produce the same set of rows regardless of which columns were queried.
Three types of Query Subjects
A query item is the smallest piece of the model that can be placed in a report. It represents a single characteristic of something, such as the date that a product was introduced.
