    <p>I have a web applications that stores data in a MySQL database on-line. It also retrieves data using PHP code, performs calculations on the server and sends the result back to the user.</p> <p>Data it's quite simple: names, descriptions, prices, VAT, hourly charges that are read from the database and manipulated on the server side.</p> <p>Often client work in environments where the internet connection is poor or not available. In this case I would like the client to be able to work offline: enter new names, descriptions, prices and use the last VAT to perform calculations. Then synchronise all data as soon as a connection is available.</p> <p>Now the problem is that I do not know what is the best way or technologies for achieving this. Don't worry, I am not asking to write code for me. Can you just explain to me what is the correct way to build such a system?</p> <p>Is there a simple way to use my online MySQL and PHP code locally? </p> <p>Should I save the data I need in a local file, rebuild the calculation in JavaScript, perform them locally and then synchronise the data if database is available.</p> <p>Should I use two MySQL database, one local and one online and do a synchronisation between the two when data is available? If yes which technology (language) shall I use to perform this operation? </p> <p>If possible, I would like an answer from PHP coders that worked on a similar project in the past and can give me detailed information on framework structure and technology to use. please remember that I am new to this way of writing application and I would appreciate if you can spare few minutes and explain everything to me like if I am six year old or stupid (which I am!) </p> <p>I really appreciate any help and suggestion.</p> <p>Ciao,</p> <p>Donato</p>

    1. COI suggest re-tagging your question - if you want this to be browser-based it's inevitably going to use javascript, the server-side technology (ie PHP, mysql etc) isn't really relevant. If you're not strictly limited to a web browser you might want to look at CouchDB ( http://couchdb.apache.org/) or similar - that's a document database that was designed for offline use & resynchronisation.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
