Apache presents the front-end on the web site, MySQL is the database acclimated to abundance information, and PHP is the middleware accent that moves abstracts amid the database and the web pages. There are absolutely bags of altered database and middleware options from which you can choose.
Create a database diagram that determines how your database will be structured. If you are application a database with a graphical development interface, your diagram can be acclimated as your database structure; otherwise, it is best to certificate your database afore you activate architecture it, so do so with a cartoon apparatus or with pen and paper.
Add a table to your diagram for the assets you charge to book. For example, if your booking arrangement is meant to handle several appointment apartment on a calendar, the apartment are the resources. This could additionally be airline seats or affair times.

Generally, these are best handled with abstracted tables of resources, or with one table for “people” and addition table for “rooms and equipment.”

For example, a accompany table ability accommodate “Dr. Smith” from the People table, “Exam Allowance 1” from the Apartment table, “10 a.m. Monday” from the Agenda table, and “John Doe” from the Patients table.
Build these tables in your database system, if you accept been clay your database separately. You should additionally accommodate placeholder abstracts (such as the names aloft in the doctor’s office), so you can analysis the arrangement as you body it with copy information.
Write the HTML web pages that will be acclimated by the bookers to cross the system. These pages about accommodate addition and documentation; a concern folio acclimated to appeal advice from the database; a acknowledgment folio assuming the requested information; a abide folio to add new information; and a submitted folio acknowledging that the acquiescence is stored. For example, a concern folio may acquiesce the user to ask aback Appointment Allowance 1 is free, or what apartment are accessible on Tuesday at 10 a.m. The abide folio would acquiesce her to book a chargeless room.
Use your called middleware accent to cull advice from the accompany table of the database as necessary, and abide advice aback into that table. For example, in a LAMP system, PHP is acclimated to action submitted forms on the web pages, again accelerate this advice in commands to the MySQL database; likewise, PHP additionally reads from the database abundance as all-important to body new pages.
Test your deployment of database, web pages and middleware with assorted booking options, again aggrandize the database or middleware arrangement as all-important to handle all booking requirements. Typically, databases of this blazon activate with simple structures and aggrandize to accord with added circuitous needs; the added time you took documenting your arrangement in the aboriginal stages will acquiesce you to handle this complication added easily.
