i using mvp structure project in c#. had imodel interface contained crud operations, have since split number of model interfaces (e.g. inotebookmodel, icategorymodel, iitemmodel etc.) each contain crud operations. would better have overall model has crud methods delegate appropriate specific models (e.g. create(string type)) or holds references each specific model in presenter? if having multiple models bad way it, how can pass down appropriate parameters model objects can created/updated? each object requires different information. having different models not bad way it. this surely make design more complex increase app's maintainability. if you're building app needs evolutionary in future upgrades, seperate model several models. in case want add different entity app. maybe books assigned persons, add ipersonmodel interface , 3 other interfaces (inotebookmodel, icategorymodel, iitemmodel) remain intact. however, if application simple , want favour rapid

Image
http://developer.android.com/guide/topics/providers/document-provider.html states: action_open_document not intended replacement action_get_content. 1 should use depends on needs of app: use action_get_content if want app read/import data. approach, app imports copy of data, such image file. use action_open_document if want app have long term, persistent access documents owned document provider. example photo-editing app lets users edit images stored in document provider. this indicates apps provides files should support both intent types. but when app supports both action_get_content (by having activity matching in intent filter) , action_open_document (by implementing document provider), shown twice when e.g. attaching a file gmail. due file picking ui showing both document providers , action_get_content matchers (the latter being shown further down below divider). is possible avoid duplicate showing of app avoid confusing users? see below screenshot , box entry sh

performance - GC in Java 8 get obviously slower compare to Java 7 -

-
i have server 72 gb memory running, use java 7 parallel gc , heap size in 25g. after switch java 8, particular task slower. task read file around 15gb in memory, , update relevant data in db. takes around 1 hour finished job, after java 8, becomes 1.5 hours. i tried: increase heap size 50gb => not help change gc algorithm parallel cms, becomes slower (1.8 hour) so not sure can start have look, java library run task still compiled in java 7 not sure if relevant? after switch java 7, performance came back. to compare/find gc issue, it's better enable gc logging: -xx:+printgcdetails -xx:+printgctimestamps -xloggc:logs/gc.log and use gcviewer parse/visualize gc log files. useful if gather gc log , attach question. in theory (and practice), java 8 faster java 7. mentioned java writes data db. may worth analyze resource consumption of both, may db root cause.
