The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

System Architecture Question

Asked by WGIT in C# Programming Language, Software/Systems Design, Design & Methodology

Tags: SLQ, Disconnected Application C#, SQL Express, Architecture

I have a Winforms applicaton that writes data to a SQLExpress Database while working offline.
The electronic Ticket is stored as a set of records in a few tables.
80+ Clients operate this way, and when they have a connection to the internet, send the records to a central database via an ASP.NET Web Service.

This has been used successfully for a year.
Another group wished to consume some of the data in their own central database.
Since they want to follow a distinct set of business rules, they wish to create an additional database on the client and in our central office to store their portion of the information.
Furthermore they do not want to use the existing web services, but have their data transmitted by the same client application via a WCF call.

This essentially splits 1 electronic document between 2 different databases both on the client, and on the office client, and does not use the existing tried and true transmission technology.

My solution is to store the records for an electronic document in the SAME database both at the client and on the central database side, and to use the same integrity and transmission checks already in place, but to integrate their validation rules in the client.

Our DBA has taken the position that as long as the data is not duplicated in more than one database, he does not care if it is split.

I am seeking opinions on this, since I do not see much technical reason in their proposal.
I am willing to be convinced othewise, but would like opinions from other application architects.

Are there any precidents for their approach?
