+## [Bootstrap](/Bootstarp/)--Auto-start settings and detection when the program is powered on
 
 1.  Reading and writing the registry under Windows enables self-starting at boot, and there are two locations where you can write;
+
     ```powershell
     HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run //对于所有用户
     HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run // 对于当前用户
     ```
+
 2.  Copy the plist file to ~/Library/LaunchAgents/ under MacOS, and use the launchctl load/unload command to achieve automatic startup at boot;
+
 3.  There are two ways under Ubuntu:
     1.  Use the systemctl --user enable/disable command to implement automatic startup at boot;
         1.  Copy the .service and .timer files to ~/.config/systemd/user/, and use the systemctl --user enable/disable command to implement automatic startup at boot;
         2.  The systemctl command is used in the .timer file, which is used to execute the .service file regularly to prevent the qxcbconnection: could not connect to display error from occurring after the graphical interface is started;
     2.  Copy the .desktop file under /usr/share/Application/ to ~/.config/autostart/ to achieve automatic startup at boot (not verified);

 1.  Log file name: application name (appname). time (time, accurate to seconds). host name. process ID (Tid). log (. count). If a single log written in a day is close to 1G, a suffix will be added automatically. (.1,.2.3..., and so on) Create a new log file to write, and rollFile will still be rolled at 0 o'clock every day;
     1.  Normal file name: LogAsynchronous.2020-04-26-20-29-03.Youth.11828.log;
     2.  The log written on that day was close to 1G, and the new file name was: LogAsynchronous.2020-04-26-20-38-55.Youth.11828.log.1;
 2.  Log format: time (time, accurate to milliseconds). Thread ID (Pid). Log level (debug). Print information (msg). File (File). Line number (Line).

-## [SqlTabview](SqlTabview/)——SQLite database call, model method;
+## [SqliteWAL](/SqliteWAL/)——Multi-threaded concurrent writing database program in Sqlite WAL mode
+
+### Advantages of WAL mode
+
+1.  Improved concurrency: WAL mode allows multiple readers and one writer to access the database at the same time, which can improve concurrency and performance;
+2.  Crash recovery: WAL mode ensures that the database remains consistent in the event of a crash by flushing all changes to the log file before committing the transaction;
+3.  Improved write performance: WAL mode allows concurrent writes, which can improve write performance better than the default rollback mode;
+
+### Things to note about WAL mode
 
-## [TableViewModel](TableViewModel/)——Table view;
+1.  WAL mode is only available in SQLite 3.35.5+ versions;
+2.  Increased disk usage: WAL mode requires more disk space than rollback mode because it writes all changes to the log file before committing them;
+3.  Slow read performance: In WAL mode, read operations are not blocked by write operations. If read and write operations are performed at the same time, data inconsistency may result.
