*{{Version badge 1}} The [[ImportCumulusFile|article here]] describes a method that can be used with Cumulus 1 to mimic the contents of dayfile.txt in a database table. However, be aware that the later versions of that script have been edited for MX, so you will need to use an older version of the script that fits the version of Cumulus 1 you are using.
*[[File:Badge vMx.png]] Please see [[MX_Administrative_Interface#Standard_Daily_Summary_Table]] section for details of how '''CumulusMX.exe''' has an optional feature with a standard option to insert a new row into a database table holding columns relating to the dayfile.txt fields.
==== Using a database table ====
For examples of some of the third party tools (Cumulus [[Category:User_Contributions|user contributions]]) using the database daily summary table see [[Daily Summary#Some_example_Scripts|here]].
In my case, I also store the equivalent of what appears on my version of "thismonth.htm" each month in another database table, i.e. I have one database table column for each of the weather derivatives I show on my web page that show this month's values; it is many more derivatives than are shown on the standard web page, but some are initially hidden. Consequentially, when my daily update script detects from the date that it is processing the last day of a month, it then starts another script that reads all the rows in the daily summary table for that month, and stores the highest/lowest/total (as relevant) in my monthly_summary table (nothing to do with the "monthly" table that MX can generate from its standard log file). This monthly summary table allows me to have web pages that compare consecutive months or compare months between years. Just another example of how much you can get from just one (daily summary) log file!
==== Alternative schemas ====
Of course you do not need to exactly mimic the log file with the schema in your database table, your weather station may not produce solar values so those fields in dayfile.txt need not be columns in your database table, or you may wish to add other values from external sensors or other log files.

**With Cumulus 1, you would need to be a programmer and write your own script to update the database table with your own schema. You might use the importCumulusFile article to start you off.
**You might also, as I did, want your script to validate what it reads from the daily summary log to ensure only valid numbers and times are stored in your database table, while any invalid inputs are stored as nulls by your script. In my own case, my daily summary table has no solar columns but it does have several additional columns (including the daily increment of chill hours, the cumulative chill hours, the contents of the Weather Diary, the time of the last rain tip, wind bearings as compass characters (e.g. NNW) as well as numerical bearings). When I used Cumulus 1 I wrote a PHP script to find all these additional values, for example it reads the [[today.ini]] and [[month.ini]] log files as stored in the end of day backup (not the ones being updated for new day in data folder), and the [[log.xml|weather diary in log.xml in data folder]]. ▼

**MX allows you to specify a different schema in the SQL it generates, but it does not offer that validation feature I just mentioned.▼
**MX automatically stores all end of month figures as log files, a feature that Cumulus 1 and 2 lacked, but as yet it does not actually use this extra data, and provides no simple facility to put what is in these files into database tables. There is no end-of-month selection for updates in MX, so you can't easily get as much from dayfile.txt as I do.▼
