    <p><strong>I see a few issues with the idea of persisting business data using object serialization:</strong></p> <p><em>These aren't necessarily show-stoppers for the idea, but rather something to think about...</em></p> <ol> <li>The data can't be queried, reported or inspected. It's entirely opaquely captured by the application.</li> <li>Debugging serialized data is harder than being able to view the corresponding data in a database, or even a format like CSV.</li> <li>There's no atomicity - it possible to corrupt your entire "database" with one power failure or application crash.</li> <li>If the data model changes, updating the existing persisted entities requires a version of the app that can read both the old and new format. With a database, you can just add a column (or sub table).</li> <li>There's no clean way to implement concurrent access. What happens if more than one user want to view or edit the data?</li> </ol> <p><strong>One thing I've learned, is that small apps tend to grow and become "large apps".</strong> When organizations guess incorrectly about the potential value of an application, they tend to incur the costs of this kind of unexpected, organic growth later. </p> <p>You also mention that you liked at SQLLite and didn't like it. What is it that you didn't like? What kinds of problems did you anticipate? </p> <p>If you're just looking for a way to "cut corners" to get this done quicker - that may be ok in the short term - but be careful - <em>these kinds of decisions have way of coming back to bite you</em>.</p>

    1. COPoint 3 is something I forgot about and very valid. Point 1 is less of an issue with LINQ to Objects. 2 is also valid, I had considered saving to CSV or XML. I guess I'll explore SQLite some more before I decide for sure.

    2. COAfter playing around with SQLite and System.Data.SQLite from http://sqlite.phxsoftware.com/ I decided I will go this route.

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).
