Q&A databases can be converted to a true relational database
using Java as the programming language. This simple demo illustrates what a converted Q&A might look like.
This demo was based on the DTFWIN DEMO (see below), which uses a combination of Q&A Windows and our DTFWIN
program. If you want, you can download that demo and open the databases with Q&A Windows to compare
what their forms look like to the Java demo equivalents.
The demo is of an extremely simple order entry application, with an ORDER, CUSTOMER, and STOCK database.
Why would you want to convert to something other than Q&A (or Sesame) when it is so easy to use?
The basic answer is that it is an end user databases, designed for people who run their business
by day and program Q&A by night.
Many of our clients were the original developers of the Q&A databases currently in use.
However, their businesses has been so successful that they have outgrown the capabilities of Q&A.
Now when they need more features to support a more complicated business,
they no
longer have the time to do further development, let alone learn something entirely new.
As professional software developers, we at Software Services and Products can convert your Q&A databases to
a true relational database and reprogram it in Java. With a true relational database, you have "scalability,"
which means that the amount of data you have can grow virtually without limits because, if needed, you can
pick and choose another database to stand behind your application, a database with greater capabilities.
Programming it in Java means we are not constrained by the limitations of an end user database. We can deliver
virtually any functionality you want. Data in multiple databases can easily be updated on the spot, with
no need to wait for later batch posting processes run by hideously large DOS macros. We can also build web-based access to your
data.
To run the demo, you need to have Java installed on your computer. Java was developed by Sun and can be
installed at no charge. Your computer may already have it installed. Download the demo and try it. If you don't
have Java on your computer, send us an e-mail and we'll provide download instructions.
