SQLite and multiple users
The UNICOM Intelligence Data File CDSC writes to a SQLite database, which has limited support for concurrency. While multiple processes can access a single database file at the same time, SQLite is designed to allow only one process to update the database at any given moment.
SQLite uses locks to control access to the database. However, file locking may not always work properly on all file systems and in all environments. As a result, you should use caution whenever a database might be updated by multiple UNICOM Intelligence Data File CDSC users.
