(2) CRM management software in C / S structure and the B / S structure, distinction, explain in detail the management CRM software C / S structure and the B / S structure, the advantages and disadvantages.
The traditional C / S problems:
(1) client rather large and a bit complicated to install.
(2) the client need to configure the connection information in the database, the client software, connected directly with the database, there are security risks.
(3) the amount of data is large, the client response is slower. Because the client make server-side data via LAN to download to the client computer further analysis and processing.
(4) system upgrades inconvenient, functional upgrades, because it functions on the client to achieve, made it necessary to upgrade each client.
(5) The long-range use of flexible, if you want remote access to the necessary ports to internet open database, enterprise data is a major insecurity.
4. Three-tier C / S structure, the management software CRM software application is a more perfect
Three-tier C / S structure software, whether in the past, present, or in the future are strong function of the mainstream of enterprise management software application platform. (B / S structure is one of them, but it is IE browser and the WEB server that is limiting die, it is not possible applications in a complex function of competence.)
Three-tier C / S structure is divided into the applications layer, function layer and data layer of three parts. Its solution is: a clear division of these three-tier, and logically led to independence. Popular talk is: the client is a simple exe program on the server side is an application server, a database in the background. The client request to the application server - "calls to the database, application server, data and processing -" then the data returned to the client. Function in the server-side implementation, the client is not directly connected with the database.
Three-tier C / S structure, there is no such B / S and the traditional C / S the problems, has good stability of cross-platform, usability, tight data security. This structure technology development threshold is relatively high, have been a number of large software companies and some technical strength of the widely used software companies, such as UF and Kingdee. |
