 Organizing and grouping - package diagrams ◦ role ◦ basic concepts ◦ advanced concepts ◦ examples 2

 Package diagram is a graphical representation of the logical structure of the system as a set of packages combined with dependencies and decomposed. These diagrams are used for grouping and organizing complex project documentation. 3

 Package - a general-purpose mechanism that is used to organize the elements of a group. Package may include a variety of UML classifiers, complete diagrams, class libraries, subsystems, models or templates.  Dependency - the basic way to combine packages into a logical structure, which results in creation of package diagrams  Package nesting/decomposing – a natural way to organize packages, which can be multilevel 4

5 Package Dependency

6 Nesting/Decomposition

 Stereotyping of packages: ◦ model stereotype ◦ subsystem stereotype ◦ template stereotype ◦ class library stereotype  Stereotyping of dependencies: ◦ import ◦ merge ◦ access 7

 Model stereotype - describes the packages that are models; common model stereotype packages represent use cases models, business models and analytical models  Subsystem stereotype - is useful in modeling systems decomposed into hierarchically ordered packages  Template stereotype - describes a package which is model solutions to problems in a given field  Class library stereotype - describes a package which groups system components to be used by other packages 8

 Import stereotype - describes commonly used dependency, meaning inclusion of classifiers, which are inside the target package into the source package during the operation of the system  Merge stereotype - leads to merging of classifiers which are inside the target package with the classifiers included in the source package; such merging dependency means that the classifiers from the source package inherit from the target package, but only within the classifiers of the same type, identical names, with "public" visibility  Access dependency - means that the source package can access the contents of the target package without physical download of data 9

 identification and labeling of packages  classification of identified packages using appropriate stereotypes,  identification of packages nesting/ decomposition,  combining packages using dependencies,  specification of dependencies by giving them appropriate stereotypes 12
