this is a simple software company database 
important ##--------------##
when trying to delete a field name it may show an eror saying you cant delete because feild has engineers
in projects you can add tool delete tools and when triying to add new tool to a devolpment stage YOU DONT HAVE TO FILL ALL TOOLS JUST THE ONES YOU WANT 
example : i allow you you to add for six devolment satges but infact you can fill one only or too or what ever you like 
each project can have multiple milestones 

in the code if you want to check the TRIGGERS i have go to 
@delete inside engineer module 
@delete tool inside projects module 

in the code if you want to ceck the NESTED QURIES
@there every were!!!

i have forein key and some comit statments and transtiions and aslo a prepare stmt

befor trying to run the aplicatin please create a new database name (mydb)

***i have exported the data base if you want 
*also note when entring data you need to enter the date in a spesfic format

code overview :i have one index page that have the file to include so in each file we can get the mudule name and page name and most of the pages loop back to themselfs

and i guess that's it have fun ;)
