    For inclusion in a library of code it needs to be totally general in terms of its interface and it needs to deal with any errors that could be encountered. In other words it should be able to be used without knowing how it works just what it does. It's almost right, however if you were to...

    HSC question

    The examiners know the answers to the questions they think they asked. Its just that often various different (and often legitimate) interpretations don't emerge until marking. I guess its a function of the BOS's security, they can't have too many people looking over the exams beforehand.

    HSC question

    Emails from the site often are not forwarded or take some time to forward. The next revision of my text (which is a few years off) will include both views of operational feasibility. The question you mention refers to 'users experience' hence implying the Excel definition. However they could...

    Here it is.... Hi everyone, Some comments on 22(b)(ii) in the SDD HSC. Exam committee members, please take these comments as constructive criticism. I just feel for the students who had to answer this question and for the poor buggers who've got to mark it! Anyway here's my...

    HSC question

    I suspect your question was in regard to my treatment of feasibility studies compared some other texts. My text considers the feasibility of actually developing the solution, ie Can the software be produced? In this context operational feasibility refers to the ability of the developers to...

    Teaching yourself SDD.

    I suggest you go back and read my post... No, none of those are reports. Furthermore it's a pretty pointless exercise to create any of these models after the coding is complete. Maybe for maintenance, but even that's a pretty thin reason. By the way EBNF is used to describe the syntax of...

    HSC question

    Perhaps these are merely some of the data types that were acceptable answers for fields within each message. They are certainly NOT examples of messages. HTH Sam

    The code is VB6, it's question 14 of Set 5D in my SDD prelim text. However it has not been copied correctly from the text (as JOn quite rightly points out). JOn's corrections are essentially correct as is his description of what the algorithm does. Here's the original: Public Sub...

    Teaching yourself SDD.

    Actually, what most people don't realise is that SDD is about writing ALGORITHMS not code. And SDD is about the total software development process NOT just writing code. It is true that those who are capable programmers usually are able to write good algorithms, however this does not mean they...

    HSC question

    If true then that's a major concern. I don't have the 2002 standards package at hand but I'll check! Actually it's question 23. If students got 18,19 or 20 for the answer you quoted then clearly no students had any idea what the question was asking! The answer you quoted is not just poor...

    Converting

    To convert hex to dec why not just do it directly... eg. A4 = (10*16) + (4*1) = 164 HTH Sam

    HSC question

    I agree that the term 'class' is misleading, in fact the whole algorithm is a total mess. I suppose they do ask for errors to be identified in (a)(iv) so maybe it's excusable. Anyway to my mind the intention of 23(a)(iii) is still pretty clear, as the question leads you to the answer by...

    Help - Project - Test data and deskchecks

    You're now doing system level testing, so you're testing all aspects of your program whilst it is actually running, a deskcheck is not relevant/possible at this level of testing, rather just report the results. Perhaps a passed/failed column and then a column describing what happened when it...

    Entity Relationship Diagram?

    The relationships screen in Access is the schema or ERD. The entities are the tables, the attributes are the fields, and the relationships are represented as the lines between primary and secondary keys in the tables (usually 1 to many). HTH Sam

    token ring

    A simple explanation... The token, which is really a packet of bits, circulates the ring. If a computer wishes to transmit data it must first capture the token. It then sends its data and releases the token. As there is only one token then it's not posible for data collisions to occur. HTH...

    Hey what exactly...

    Anyone involved in the development of software is a software developer. Hence system analysts and programmers are examples of software developers. The terms 'System Analyst' or 'Programmer' identifies the tasks they complete during software development.
