    <p>Contrary to what other people are saying, Jet is not dead and far from it: ACE is the new version of Jet and it's pretty robust and backward compatible. </p> <p>Both SQLite and Jet/ACE have their strengths and weaknesses and you need to get more information about the specific points that are important to you and your application.</p> <ul> <li>In either case you can redistribute the engine.</li> <li>Jet/ACE is a bit more integrated and supported out of the box in MS tools and Visual Studio.</li> <li>Jet/ACE has more granular locking, which may be important if your app allows multi-users or needs multi-threaded access to the database.</li> <li>Jet/ACE has more features in terms of what you would expect from a database (joins, unions and complex queries).</li> <li>Jet/ACE has a simple migration path to SQL Server, so if your database needs become big, you could move to SQL Server fairly easily.</li> <li>SQLite is cross-platform, so if your app needs to be ported to Linux/Mac under Mono then SQLite is a better choice.</li> <li>the SQLite engine is tighter so redistributing may be easier.</li> <li>datatypes are quite loose in SQLite.</li> <li>SQLite has more liberal redistribution rights (since you can basically do whatever you want with it).</li> </ul> <p>People who say that Jet corrupts databases are stuck in 1995.</p> <p>In the end, unless your application has some very specific requirements that are pushing the boundaries of either database engines, then it probably doesn't matter which one you chose.<br> Just use the one that easiest for you to include in your project.</p>

    1. COSQLite also supports joins and unions: sqlite.org/lang_select.html. Maybe you meant that it does not enforce the integrity of foreign keys?

    2. COA db that doesn't enforce foreign-key constraints is not really a database in any real sense.

    3. CO@David: it may not matter in some cases and if you're using an ORM, it will generally handle these for you. There is a place for all of these databases, you just need to pick the one that makes the most sense for your project.

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).
