Description

SDF Viewer isn't the prettiest program; it works with SQL Server Compact Edition databases in .SDF format. Its main feature is its complete autonomy: no need to install third-party SQL Server Management Studio or Visual Studio; you just need to open and edit the database, or you can create it from scratch. According to the author, it's suitable for both pro developers and beginners.

SDF Viewer is a paid program; after launch, you'll be asked to purchase it. To avoid this, you need a key or crack. It's included in the archive at the link below, so this is the unlimited version with activation.

Features:

You can work with the database structure—create, rename, modify, and perform other operations on tables. Work with indexes and foreign keys is also implemented.
Data management also includes viewing, sorting, and adding records to tables. There's a visual query builder if you're too lazy to write SQL manually. You'll get a full-featured editor for writing and executing SQL scripts.
Import and export help you transfer data from MS Access, SQL Server, and SQL Server Express. Tables can be exported to XLS formats. Images can be imported directly into the database.
Administration and utilities provide a comprehensive set of options, including installation, changing, and deleting database passwords. File compression and recovery are also available. Older versions of SQLCE databases can be upgraded to the latest version.
Visualization is a separate topic; it will help create database structure diagrams.

Overall, the program is, again, shabby in appearance, but its functionality is incredibly powerful. For anyone who needs to quickly view an SDF file, make edits, or transfer data, this software is superb.
