School of Science, Engineering and Information TechnologyCRICOS Provider No. 00103D Page 1 of 3ITECH5403 – Assignment 1 – Language Design EssayDue Date: 5pm, Friday of Week 7This assignment will test your knowledge of programming language design features, and is worth 20% of yournon-invigilated (type A) marks for this course.Topic OverviewSince the development of Plankalkül back in the 1940s, a large number of programming languages have beendesigned and implemented – each for its own specific problem domains and made with its own set of designdecisions and compromises. For example there are languages which: Are strongly typed and loosely typed, Provide support for object orientation / abstraction of data types, Use static or dynamic scoping rules,

Provide memory management (i.e. garbage collection) or allow the developer fine-grained control overheap-allocation and recycling,
 Provide closures to allow functions to be passed around like variables, Allow easy access to array slices and those which do not, Perform internal correctness checking of data and those which do not,

Provide diverse and comprehensive suites of built-in functionality and those with a more limited set offeatures,
 Use pre-processors and macros to selectively expand or substitute source code, etc.Each of these decisions can have a profound effect on the usefulness of a programming language in terms offactors such as its speed, robustness and general suitability to create programs of a certain type, such as foroperating systems, or in the areas of business, scientific computation, artificial intelligence or video games.The topic of your essay is to design a language for the problem domain of Banking.Banking encompasses a number of areas including aspects of business, finance, and customer relations. It isworth thinking about the aspects of a banking system in terms of a number of features, including: Performance; Use and precision of data types and structures; Maintenance of code; Flexibility of design and implementation; and Robustness requirements in such a critical domain.School of Science, Engineering and Information TechnologyCRICOS Provider No. 00103D Page 2 of 3Even though security aspects are worth considering, the features of the language are the primary concern inthis essay.With this in mind your task is to theoretically design a language suitable for the use within the banking domain.The actual implementation of the language and tool set is obviously outside the scope of this course, but youmust express and justify the design decisions behind your programming language in terms of:

The features and functionality that will allow your language to be suitable and useful within the bankingdomain (including what differentiates it from existing languages),
 The programming paradigms, such as procedural, object oriented, logic and functional programming.You are free to design your language to be either interpreted, compiled or to work in a hybrid manner, but youmust thoroughly justify your decision.All language design choices must be sound, rational decisions which are backed up by robust discussion ofthe subject area. In addition, your document should include numerous references to back up any and allspecific claims that you make. All references should be made in the APA referencing style.Submission and Marking ProcessYour essay should be between 3,000 and 4,000 words inclusive and may contain diagrams or images as yousee fit. All diagrams, charts, images or other externally created materials incorporated into your essay must beappropriately referenced.You may supply your completed essay in either Word or LibreOffice/OpenOffice format in which the documentcan be edited – no proprietary Mac specific formats, please.Assignments will be marked on the basis of fulfilment of the requirements and the quality of the work.In addition to the marking criteria, marks may be deducted for failure to comply with the assignmentrequirements, including (but not limited to): Incomplete language feature coverage, Incomplete submissions (e.g. missing subject areas – see the marking guide), Poor spelling and grammar, and Incorrect adherence to the APA referencing style.Submit your document to the Assignment 1 Upload location on Moodle before the deadline of Friday of week 7at 5pm.The mark distribution for this assignment is outlined in the provided marking sheet on the following page.School of Science, Engineering and Information TechnologyCRICOS Provider No. 00103D Page 3 of 3ITECH5403 – Comparative Programming LanguagesAssignment 1 – Language Design EssayStudent name: Student ID:
