c# - What are my controller in my application with a MVVM design pattern -

-

i have developed wpf-application. have mainwindow inherit window, tabcontrol , many tabitems in tabcontrol inherit usercontrol. every tabitem has own cs-file, code in c# businesslogic, , xaml-file development of ui done. have sql server database connect trough linq.

so have write choice of controller use in application. confused, since havent manually programmed controller , thought viewmodel behave controller in case. correct? can viewmodel behave controller?

a controller can send commands associated view change view's presentation of model (e.g., scrolling through document). can send commands model update model's state (e.g., editing document). model_view_controller

the viewmodel “model of view” meaning abstraction of view serves in mediating between view , model target of view data bindings. seen specialized aspect of controller (in mvc pattern) acts converter changes model information view information , passes commands view model. view model exposes public properties, commands, , abstractions. model_view_viewmodel

the introduction of mvvmc (mvc + mvvm) nessesary in cases drive many similar pairs of view-viewmodel (use cases). can introduce controllers. model_view_viewmodel_controller

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
