algorithm - Client and server: data filtering and sorting synchronization. -

-

i have java client-server crud application. in client open person table , can set filter example city,age,sex. besides can add sorting rule, example sort name,and after age. these filtering , sorting rules sent server passed sql dao , used in sql code. server returns dto client according filtering , sorting rules. it's important - server implements these rules client passes these rules server. easy , clear.

now create new person in client application. newly added person must visible in table of persons. , came across problem. how add person table according filtering , sorting rules. solution see make client refresh data server according same rules. obvious bad solution.

i sure common problem crud application. possible solutions: patterns,algorithms,libs? name of problem (if exists)

the broad category of problem layered architecture (an architectural pattern) , question deals run domain logic of system.

on client-server systems decision needs made processing should occur. there broadly 3 different options:

1) run on server

this simplest case. great advantage simple upgrade , fix because it's in limited places. downside clients need make roundtrip server simplest functionality , causes user experience suffer. maintenance point of view best option.

2) run on client

the general arguments in favor of processing on client user interface responsiveness , disconnected operation. in case server acts dumb datasource. many times if need move logic client best move there - @ least in 1 place then. however, keeping clients in sync , avoiding compatibility errors brings challenges.

3) split processing between client , server

this option may have deficiencies of both worlds. main reason there small amount of domain logic needs run on client. trick isolate common functionality own self-contained module isn't dependent on other part of system. way can run module on both client , server.

the simplest option go (1) client send new person data server , server return updated, sorted , filtered person list client. requires server round-trip , may hurt user experience.

the other option go (3) duplicate domain logic of server on client. way forward isolate person handling module can use on both ends.
