To check if a user has access to a specific record, implement an access control mechanism: 1. Fetch the user's access level and permissions from your database. 2. Use these details to query the record's permissions. 3. Return true if the user's permissions match, otherwise return false. Example code snippet in SQL might be: `SELECT * FROM records WHERE user_id = ? AND record_id = ?;`
