For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

SQLite is a database that's well suited for smaller volume applications as it embeds within the application rather than running as a separate server. Cleverly written, it overcomes the issues which have previously pushed even quite limited applications into using a client / server model. And it's built in to many of the products that we teach, so it's likely there and ready for your use.

4024SQL databases from Python - an SQLite example
There's a new example of relational database use in Python [here] on our site - from the Python course I ran last week. If you cut and paste the script onto your system, it should run with little fuss (and without needing a separate database engine) as it uses sqlite - the built in SQL database - as ...
4007Which database should I use? MySQL v SQLite
Which SQL Database would I advise newcomers with a new application to use? Five years ago, MySQL would have been the obvious choice in many circumstances. But these days, MySQL has grown into a much bigger product and there are very serious licensing and other commercial issues that need to be considered; ...
4006Ruby / SQLite3 example program, showing JOIN v LEFT JOIN
Ruby includes support for the SQLite3 database ... and SQLite is an excellent tool for developing and testing ("Spike solutions") your database structure and concepts before implementing a larger system. For a smaller and straightforward requirement, SQLite may be all that you require. Towards the ...
3269Files or Databases? MySQL, SQLite, or Oracle?
Are plain files a bad idea? Should you use a database instead? Plain text files are a great way of saving data in some circumstances ... but in other circumstances they have "issues": 1. If you're saving columns of data in a plain text file, you need to have some sort of separator between the columns, ...
3139Steering our Python courses towards wxPython, SQLite and Django
With our modular courses that we write ourselves, we've well placed to move forward with technology; more often than not, what's needed is a series of gentle changes, adding in the occasional module for private courses where a particular new subject is needed, with it being introduced into public courses ...
3099Perl - database access - DBD, DBI and DBIx modules
Perl's DBI module provides an excellent link from SQL databases to Perl, and the assorted DBD modules that fit underneath it allow it to operate well for a whole lot of different databases. But they are only excellent as far as they go - for the SQL statements have to be generated in your application ...
2786Factory methods and SqLite in use in a Python teaching example
I've just uploaded a neat little example - [here] from last week's Python course - it's amazing what you can do in a very few lines of code. The application scenario is that we have a database of customers - some are residents at our hotel and others are delegates on our courses. Being mercenary folks, ...
2744PyQt (Python and Qt) and wxPython - GUI comparison
We're running a tailored 3 day Python course at present, using Python 3 if it's practical, and today we compared the two contenders for the "Top GUI" prize - that's Python with Qt (PyQt) and wxPython. Now wxPython isn't yet available in Python 3, but PyQt is - although some of the documentation refers ...
2746Model - View - Controller demo, Sqlite - Python 3 - Qt4
The Model - View - Controller approach to application design keeps the Graphic User Interface (the view) separate from the database (the model), with the controller in between the two, describing how the data is displayed, and how changes to the data are saved away in the database. By separating the ...
2745Connecting Python to sqlite and MySQL databases
For developing a Python application, and for light use, the SQLite database may be a good choice ... but then you may want to be able to expand the system to use a central database with a more classic server such as MySQL at a later date. Using Polymorphism in Python, and with a careful choice of which ...
2561The future of MySQL
MySQL has grown from a very neat little open source database 10 years ago into a very powerful and widespread database that's not always fully open source any longer today. The MySQL company was bought out by Sun a couple of years back (January 2008), and in turn Oracle are now buying Sun. This deal ...
