Database Application Design Concerns


i redesigning invoice log application had designed in access.  one thing access took care of me confused on concurrency.

my original plan build custom invoice , invoice collection class load when program opened , work off it. or load dataset , work off data in it. 

however im not sure how handle concurrency in these scenarios.  since access shared same file have 6 processors opening 6 different apps , loading 6 different datasets if made change in 2 of them how handle this?  

 

 

 

coding 4 god!

i don't think link being rude nor condescending. used "managed" in context of choosing use sql server versus oracle or mysql... easy big fella, there many here many cultures trying use english common language.

 

the platform choose depend on research , preference cost, functionality, hosting requirements etc... question needs more details on how users access data either client/server app, asp web page etc... , answer need brief overview of main database engines offer.

namely: sql server, sql express ( free ), oracle, mysql, postgressql, , others.
