So, I’ve tried to summarize the experience personally I had exploring functionality of below listed web-based apps. This is a brief description in alphabetical order:
Your front-end must be completely integrated into your web site? Are you a newspaper? A lot of your competitors are already using Caspio Bridge. You can be the next. If you are curious how MS Access would look if it was completely made on web-browser check out Caspio Bridge.
In case you need easy to use tool for data analysis over the web Dabble DB is your choice. This is not some useless web-based Excel clone, but a system with its own approach and philosophy. I think you’ll like it.
Are you searching for not that expensive solution as Salesforce? Check out LongJump. The system may even surprise with more powerful functionality than Salesforce in some areas. But I guess its complexity makes the system not so good for small business.
Looking for a solution from a mature vendor? Your budget isn’t strictly limited? Want a system with a time tested functionality and opportunity to create a full-fledged app? Try QuickBase. Besides, no developing skills needed.
Want to build a complete application, but QuickBase is too much for your budget? Check out TeamDesk. Salesforce styled interface and robust functionality is there for building a complete solution. If you can write few formulas in Excel, than you'll handle TeamDesk easily.
Looking for something simple to manage a couple of tables? Try TrackVia. Easy to use and learn, but in case you’ll need something more complex in the future, no way to do this within the system. I think the system is a bit costly for such a limited functionality.
Can’t reckon it up: tested not that much. It takes some effort to master a non standard interface though. From the first sight I can tell the WorkXpress is robust enough
If you are a programmer or pursue it, but PHP or ASPX scare you try Zoho Creator. Mastering Deluge Script is not easier, but you can do a lot with scripting.
Of course, this is my personal opinion and vendors can disagree at some points. Anyway, it never hurts to take it into consideration in case remarks are really reasonable. Well, we'll see if any...
Due to Treff LaPlante (WorkXpress President & CEO) concern:
"Further, when compared with the other reviews, it places us quite falsely in a negative light. If your intent is to print an incorrect review, then please let it stand; time will reveal the truth. If you acknowledge that maybe others who have spent more time with the platform overcoming the "non standard interface" are seeing some potential here then I encourage you to amend your review to focus on the lack of time you’ve spent with it."
Corrected. We’ll see what time reveals.
