Client-Server Application
Client-Server applications designed from source MS Access databases are typically written in Java or one of the Microsoft .Net languages (C#, Visual Basic .Net), and designed to run against a SQL Server or Oracle Database server. With a Client-Server migration approach, your source MS Access application serves only as a functional prototype for the new application — no components of the MS Access application are used following project completion.
The result is high application performance, tight security and the most robust user experience. Application deployment can be automated and may be restricted to MS Windows PCs. As a true Client-Server application, with a relatively small local PC memory requirement, the Client-Server approach enjoys standard Windows deployment and security coupled with high-end database server performance and robust security.
Client-Server Scorecard
| # End Users | <: 1000 | Supports continual use |
| Deployment | LAN Only | WAN or Internet use not recommended |
| Performance | Excellent | SQL Server design-dependent |
| Reliability | Excellent | SQL Server design-dependent |
| Data Integrity | Excellent | Assumes proper use of SQL Server database constraints and keys |
| Security | Excellent | SQL Server-level security controls |
| Data Limit | Unlimited | SQL Server datastore |
| Maintenance | High | Distributed application maintenance |
| # of Records | Unlimited | SQL Server datastore |
| Internet Access | No | Remote access will substantially impede performance and reliability |
Client-Server Architecture
Typically deployed to a network share, MDE Access Client-Server applications are recommended for non-regulated, shared data across a LAN, for example, inter-department management of statistics and production analysis. MDE Access Client-Server applications are limited to LAN deployment. Large front-end applications can be slow to load over a WAN. The MS Access Client-Server approach does expose the data tables directly to the End User, which can present security or data integrity issues.
