4DL File Extension

4th Dimension Database Log File – file format by 4D

4DL (4th Dimension Database Log File) is a file format developed by 4D and used to store database log files. These files contain a record of all changes made to a database, including the date, time, user, and type of change.

4DL File Format

A 4DL file is a database log file used by 4th Dimension, a cross-platform relational database management system (RDBMS) developed by 4D. It stores a record of database changes, including updates, insertions, and deletions. The 4DL file is used for data recovery and auditing purposes, allowing administrators to track and restore changes made to the database.

Technical Details

4DL files are typically stored in a proprietary binary format that is specific to 4th Dimension. They contain a timestamp, the details of the database change, and the user who made the change. The size of a 4DL file can vary depending on the volume of database activity. 4DL files are an important component of the 4th Dimension database system, providing a way to track and manage changes to ensure data integrity and maintainability.

4DL File Format Overview

The 4DL file extension is associated with the 4th Dimension Database, a cross-platform database management system developed by 4D. A 4DL file is specifically a database log file that contains a record of database transactions and changes. It serves as a valuable backup in case of database corruption or accidental data loss.

Opening and Using 4DL Files

4DL files can be opened and viewed using the 4th Dimension Database application. To open a 4DL file in 4D, follow these steps:

  1. Launch the 4th Dimension Database application.
  2. Select “File” > “Open” from the menu bar.
  3. Navigate to the location of the 4DL file you wish to open.
  4. Select the 4DL file and click “Open.”

Once the 4DL file is open in 4D, you can view the database log. The log contains detailed information about database transactions, including timestamps, user IDs, and the nature of the changes made. This information can be useful for debugging database issues, tracking user activity, and ensuring data integrity.

4DL File Format

A 4DL file is a database log file created by 4th Dimension, a relational database management system developed by 4D. It records changes made to a database, including additions, deletions, and modifications. The file serves as a backup and can be used to restore the database to a previous state in the event of data loss or corruption. 4DL files are typically stored in a log directory associated with the database. They can be viewed using the 4th Dimension Database Log Viewer tool.

4DL File Structure

4DL files are ASCII text files that follow a specific structure. The first line of the file contains the log file version number. Subsequent lines are transaction records, each of which begins with a time and date stamp followed by the type of operation performed (e.g., Insert, Update, Delete). The remaining lines of the transaction record contain the details of the operation, such as the table name, record ID, and field values. 4DL files can grow large depending on the frequency of database changes. Periodically archiving or purging old log files is recommended to maintain optimal database performance and reduce storage consumption.
