Introduction
The banking sector is one place where customers expect 24*7 service or we can say that there is no concept of free timing applicable in this industry. For this reason, this sector requires software which is robust, safe and fast among other things. Languages that are best suitable for this job include Java, Scala and, C++, etc. With the advent of globalization and growth of internet all the industries are going online and, so is the banking industry. This is done so that banking services can be provided 24*7 to all the customers. Facilities like checking bank balances, transfe
ing money across the globe are all available on our fingertips.
Both private and government sector banks operate their own softwares. These softwares are written in various languages understood by a computer and which are known as programming languages. A program is just a set of instructions and, multiple programs on a single platform make a software. Thus we can say that programming languages form the backbone of a software. In the modern world, there are multiple programming languages available with merits and demerits of their own.
A programming language is used to give instructions to a computer to perform specific tasks that are required by the user. This term programming language is generally associated with high-level languages. There are a number of languages available in the market. C, C++, Java, C#, Ajax, .Net, etc. are some of the commonly used languages. Apart from these Python is also a very important language used by programmers across the globe. Other than that Small talk is a unique language because of its fully object-oriented nature.
Safety is one of the most major concerns nowadays because of the increase in the number of hackers who are responsible for attacks on computers and theft of valuable data. Because of this softwares are being developed in highly secure languages. This is especially relevant in the banking sector as there is sensitive information involved and banks cannot expect all the customers to be aware of malicious activities. In order to stop this from happening, banks are ordering new softwares which are highly secure and robust in nature.
Choice and justification of interpretation\compilation method (s)
Plankalkul is credited to be the first programming language developed by Konrad Zuse between the years 1942 and 1945. As discussed earlier there are many programming languages which have their own set of qualities which make them useful in different occasions. For example some languages;
1) Can be Strongly typed and loosely typed
2) Support object oriented framework
3) Provide features like memory management using ga
age collection
4) Allow functions to be passed around as variables
5) Allow easy access to a
ay slices
6) Allow internal co
ectness of and some others don’t
7) Have diverse built-in functionalities and some have limited features
Each of these features make every programming language unique and help to differentiate it from other languages on the basis of use. But being robust and fast is expected of all the languages. The features help the end user decide which language to use dependent on the need and application which ranges from Artificial intelligence to game development.
One of the most prominent language used in developing banking softwares is ‘Java’. Java comes under the category of partially object-oriented languages. In the banking sector with years of usage Java has a pretty strong base and a lot of legacy as well as modern softwares, have their UIs developed in Java. Other than Java, .Net and C++ are other 2 prominent languages used in banking sector.
Before designing a programming language, a developer must be aware of the following important elements
1) Familiarity levels with the technology
2) Familiarity levels with terminology
3) A clear vision and aim is there
4) The semantics of the language being created which include
· What are the data types that would be a part of the new language language?
· Whether the language being designed is static or dynamic in nature?
· Is the language a domain specific one or a general purpose?
· The memory management technique to be used – Ga
age collection or Manual data handling
· What procedure to adopt to handle concu
ency? (Multithreading model/ Deadlock model/ Complex models like Linda)
· Whether the language will support primitive functions or all the functions will come from the li
ary?
· Deciding on the main paradigm to be used for this language. Options include Functional, Object-oriented, Script, Template oriented or coming up with something entirely new
· If development is done for a domain specific language, then the developer needs to clearly define the interface with the existing li
aries and languages
5) If the development is done for a domain specific language then it should be capable of doing all the domain tasks efficiently
6) Evaluate different syntax ideas
7) Come up with grammar for syntax
8) Decide on whether the language will be compiled or interpreted
9) Parser information to be used to write code
10) Make use of executor or code generato
11) Write a test program to test the language
12) Write a standard li
ary
13) Decide on debugging procedure for the language
14) Publish the language with specifications
These are the 14 steps that a developer needs to keep in mind while developing a language. When it comes to the banking sector, it incorporates a lot of functions including financial transactions, customer relationship management, etc. Thus the programming language to be designed should be suitable for...
