[snip] I am writing an attendance system in php/mysql for my school. We have a little less then 1000 students. For every day of the school year one record will be entered into a table for each student representing their attendance status (present, absent, late, etc...). I also have several other supporting tables for relationships. When it comes to reporting and querying this DB I am worried that it will very quickly become very large and slow. Can mysql handle this? Are there any techniques to speed it up? I will trying indexing major columns.
I have also considered keeping all previous days attendance in a separate table from the current days attendance and moving things over in the middle of the night. This way any operations on the current days data will go quickly, but reports on long term things will still be slow. Good idea? [/snip] The short answer is that 10000s of records is no problem dependent upon the server, good coding, and good database optimization. We process millions of records each day with PHP and MySQL (today there are 58M records to be processed). Over time we have found bottlenecks and cleared them up. This is being done on a sub-1Ghz server (but I am looking forward to an updrade!). HTH! Jay -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
