    <p>Installing one database per client PC can be tricky. I think you have a decent handle on how to deal with the issue currently. It seems like the real issue you are currently facing is debugging. To deal with this, there are a couple ways you could go:</p> <ol> <li>Have the customer upload their copy of the database back to you. This would provide you with the data they have and you could use it with a debug copy of your code to identify the issues. The downside is that if the database is large it might be an issue transferring it.</li> <li>Remote onto the customer's machine. Observe the system remotely using something like <a href="https://www.copilot.com/" rel="nofollow noreferrer">CoPilot</a>. That way you could see what is happening in its natural environment.</li> </ol> <p>There are probably other ways, but these are a couple of good ones. As for using an online database, this is an option but it brings its own set of issues with it. You mentioned a couple. As for Azure, that is cloud-based (online) so the same issues will apply. SQL CE won't help you any more than your current installation does.</p> <p>Bottom line is that I would recommend you look into the ways to fix your one issue (as listed above) instead of creating a whole new set of issues by moving to an Internet-based solution. I would only recommend moving to the Internet if it was addressing a larger business need (for example, mobility). Doing the same thing you have been doing only online will probably just make life harder.</p> <p>To recap the comments below since they are so pertinent to the issue, if you are choosing between file-based databases that don't need to be physically installed on the machine, your best choices are probably between SQLite and SQL CE. Microsoft supports SQL CE better but it is a larger package and has less features than the trim SQLite. Here is a good discussion on the differences:</p> <p><a href="https://stackoverflow.com/questions/2278104/sql-ce-sqlite-what-are-the-differences-between-them">https://stackoverflow.com/questions/2278104/sql-ce-sqlite-what-are-the-differences-between-them</a></p> <p>However, the issue gets more complicated when you start looking at linq2sql since that is designed for SQL server. Microsoft does not support SQL CE with linq2sql out of the box, although there is a work-around that will get it to work:</p> <p><a href="http://pietschsoft.com/post/2009/01/Using-LINQ-to-SQL-with-SQL-Server-Compact-Edition.aspx" rel="nofollow noreferrer">http://pietschsoft.com/post/2009/01/Using-LINQ-to-SQL-with-SQL-Server-Compact-Edition.aspx</a></p> <p>SQLite is not supported at all with linq2sql but there is a way to use linq to talk with SQLite:</p> <p><a href="https://stackoverflow.com/questions/250071/linq-with-sqlite-linqtosql">LINQ with SQLite (linqtosql)</a></p> <p>This library also supports other common databases including MySQL and Firebird.</p>

    1. CO@BiggsTRC: Thank you for agree with my methods. i think SQL CE might do a little bit of work of help as when i need to deploy my software to my client outside of my country. I might required to travel to specific country just to install the SQL Express and Studio if following my steps above which i find not very feasible. Could you correct me if my point is wrong.

    2. COAhh, I see. You want to use a file-based SQL instance in order to get around the idea of installing SQL Express. In that case, yes, that would work. You could also look at SQLite to do the same thing.

    3. CO@BiggsTRC: comparing SQL CE and SQLite, which one would you think the best? To me, it seems like the SQLite is storing at client site, and client would required to send me the database if i need it for debugging.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
