[Year 12 SofDev] Real world problem

Wed Apr 3 01:13:20 UTC 2019

Hi All,

I just re-read my response, and I must apologise – there are lots of grammar and spelling mistakes.  Very poor form, that’s what you get when you rush something.

But I hope my message was clear, pick the appropriate technology that is suitable for the situation and also enables students to demonstrate a very high on the criteria.

Cheers

For Python users, XML has native support (though there are lots of modules that also do this - some quite elegantly). It is very easy to read and write files and is a much better option than linking to a database (from the perspective of mobile deployment).

Cheers,
Adrian

Chris has nailed it
I generally use text files, then during the folio phase I change a file structure so then that can introduce xml

In the SAT I generally let them choose - many pick text files but note in the documentation that it requires effort to change the data structure and that it is not easily scalable and not easily transferable. etc

I have used access with VB.net<http://VB.net> - the only issue is that it requires students to understand access as well - sometimes well beyond some students except the most able. The actual techniques are do-able BUT do you really want to add that level of complication to something that is already a mighty task?

Hi David,

James is 100% correct.  Choose the technology that is most appropriate for the solution.  It the solution is a data driven web solution then a database would be most appropriate.  If the solution is a native mobile app and requires storing state data locally then an XML file might be appropriate.

XML is accessible on the exam but that doesn’t mean we should just use it for all data storage.  We taught it in U3AoS1 – and might have even used it as part of SAC, but that doesn’t mean that we should just use this one technology.

The SAT gives our students the opportunity to experience the fun of developing a complex software solution that is relevant to them and part of that is to pick the technology that is most appropriate.  And with the study design having the key knowledge point:

  *   “formatting and structural characteristics of input and output, including XML file formats”
then choosing the appropriate technology ensure that students will actually need to understand this.

Also for VB.Net<http://VB.Net> it not really that bad to get data out of an access database if you use ADO.net<http://ADO.net> with an OleDb data provider and DON’T bind the controls to the dataset (email me directly if you want my resources).

I recommend making sure students use XML because it’s on the exam.

Access can be tricky. Search for “Firchild” on YouTube. He has made about 7 videos on how to set up an Access db with VB.

Good luck.

Hi David

Over the years, linking in with Access databases was just one way that my students did it. Some used SQL databases (using XAMPP – pretty safe if students only have the virtual servers on when they are using it), other have used plain-text files, whilst others XML files.

Ultimately which external storage technology students use should be dependent on the solution’s needs. What is the best storage technology that meets my needs and is feasible?

Thank you very much for your help. It is great to see the level of the projects.
I wonder if I can also ask you / anyone what technology you resort to for the ‘design, construct and use of external storage’ within the programming requirements?
I have been looking at interfacing VB.net<http://VB.net> with an access database. Is that a common way to achieve the external storage requirements?
Thank you.

David.

Also, as this is my first year with Software Development (the course not the skill) does anyone please have any examples whatsoever of a ‘real world problem or opportunity’ called for by the Software Development Administrative information for school based assessment 2019?

Just one or two that students have selected in the past would be helpful to look at.
Thanks,
David.
