Project is ready to make C/S and B/S two parts; The middle layer using Delphi development of Com +; B/S part using C #, C/S and B/S program can be used at the same time the middle layer, without the need to develop two parts, the problem now is that the middle layer is not using Midas, use you transmit data directly to the calling side, so that at the time of the client to use, as we commonly used master-slave tables should be how to update? Because when we get the data from table often use the Join method is presented, and you in the update time often couplet BHB also updated, if it is in the client spelling a SQL statement updated, I think this also conflicts and three layer development, others say you pass in a single table to the client, so not to increase the data traffic? And we is not the primary key of the automatic growth, but generated using data in the table, that this generation I think should be in the middle tier, and should not be on the client side processing, but not consider how to deal with good, don't know if you have encountered this problem, also please do a three-tier friends advice, discuss everyone do the three layers of master-slave update when using what kind of method to update the data, to welcome you all to discuss

By themselves

CodePudding user response:

No one is to introduce development experience a three-tier system

CodePudding user response:

Wash brush, and introduce a three layers of development of things

CodePudding user response:

Only a c # is right
Should not only use Delphi
