PROGRAMMING LANGUAGES

MYSQL

Mysql is the world's most used relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases.

Mysql is one of the most popular relational databases Management System on the web. The Mysql Database has become the world's most popular open source Database, because it is free and available on almost all the platforms. The Mysql can run on UNIX, window, and Mac OS. Mysql is used for the internet applications as it provides good speed and   is very secure. Mysql was developed to manage large volumes of data    at very high speed to overcome the problems of existing solutions.     Mysql can be used for variety of applications but it is mostly used for the web applications on the internet.

Advantages of Mysql:

Reliability and Performance: It is very reliable and high performance relational database management system. It can used to store many GB's of data into database.

Availability of Source: its source code is available that's why now you can recompile the source code.

Cross-Platform support: It supports more than twenty different platforms including the major Linux distribution .Mac OS X, UNIX and Microsoft windows.

Large pool of Trained and Certified Developers: It is very popular and it is world most popular open source Database. So it is easy to find high quality staff around the world.

Powerful Uncomplicated software: It has most capabilities to handle most corporate database application and used to very easy and fast.

PHP

PHP is a general-purpose server-side scripting language originally designed for Web development to produce dynamic Web pages. It is  one of the first developed server-side scripting languages to be embedded  into an HTML source document, rather than calling an external file to process data.

PHP language has its roots in C and C++. PHP syntax is most similar to C and C++ language syntax. So, programmers find it easy to learn and manipulate. Mysql is used with PHP as back-end tool. Mysql is the popular online database and can be interfaced very well with PHP. Therefore, PHP and Mysql are excellent choice for webmasters looking to automate their web sites. PHP can run on both UNIX and Windows servers.

Advantages of PHP:

PHP is accessible

It's available for free. It's available with documentation in many languages. There are many support groups, forums, and teams supporting PHP. There is a wealth of online information regarding PHP.

It's quick to develop in PHP.

 A basic PHP script can be created without a firm understanding of programming principals, compilation, and other currently important programming concepts.

PHP is loosely typed, which makes basic scripts much faster to develop with less attention to design.

Programmers of Java, PERL, BASIC, and other popular languages can find many parallels to ease transition to PHP.

PHP is flexible.

It runs on many different operating systems.

It can be optimized, even "compiled" for performance closer to that of more established compiled languages.

PYTHON

Python is a general-purpose, high-level programming language whose design philosophy emphasizes code readability Python claims to combine "remarkable power with very clear syntax", and its standard library is large and comprehensive.

It features a fully dynamic type system and automatic memory management, similar to that of Scheme, Ruby, and Perl. Like other dynamic languages, Python is often used as a scripting language, but is also used in a wide range of non-scripting contexts. Python uses dynamic typing and a combination of reference counting and a cycle-detecting garbage collector for memory management. It is also important to mention that Python has fewer "dialects" than other languages, such as Perl. And because the block structures in Python are defined by indentations, you are much less likely to have bugs in your code caused by incorrect indentation.

Advantages of Python:

Readability: Python's syntax is clear and readable. The way Python's syntax is organized imposes some order to programmers.


It Is Simple to Get Support: The Python community always provides support to Python users. As we already know, Python code is freely available for everyone. Therefore, thousands of developers worldwide are working hard to find bugs and create patches to fix those bugs.

Fast to Learn: The language is very easy to learn because its source code resembles pseudo code. It doesn’t ask for long and strange lines of code. Therefore, less training is a direct result.

Fast to Code: Python provides fast feedback in several ways. First, the programmer can skip many tasks that other languages require him to take. Therefore, it reduces both the cost of program maintenance and the development time.

Reusability: Python encourages program reusability by implementing modules and packages. A large set of modules has already been developed and is provided as The Standard Python Library, which is part of the Python distribution.

Portability: Besides running on multiple systems, Python has the same interface on multiple platforms. This means that you can write a Python program on a Mac, test it using a Linux environment, and upload it to a Windows server.

Object-Oriented Programming: Everything in Python, as in Smalltalk, is designed to be object-oriented. You can start programming using non-OO structures, but it doesn't take too long for you to find out that it is much simpler if you use its OO features. Some of the implemented OO functionality in Python is inheritance and polymorphism.

PERL:

Perl is a high-level, general-purpose, interpreted, dynamic programming language. Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications. Perl is procedural in nature, with variables, expressions, assignment statements, brace-delimited blocks, control structures, and subroutines.

In the web development environment, Perl is a very powerful way to create dynamic web pages. Perl can be used for virtually any web application you can think of, from hit counters to database management.

Advantages of PERL:

Cleaner Codes: Cleaner codes of Perl which can be read very easily. It enables the use of mnemonic identifiers instead of cryptic variables. Therefore, there will be warnings to warn if there is any mistake done in the code.

Modularity & Reusability: As for the modularity and reusability, users can easily make use of the Perl library because everything is defined in terms of modules and component and everything can be easily shared


Object Oriented Programming: Perl language uses object oriented programming where it supports dynamic inheritance and virtual methods making it simple and straightforward.

Compatible & Extensible: Perl programming language is highly compatible and extensible because you can embed it into C or C++ applications. Perl language also supports dynamic module and it can transform itself into a dynamic library.


Multi-Simultaneous DBM Implementation: With Perl, we can have multi DBM implementation because it can simultaneously access DBM, GDBM, NDBM and SDBM from the same script.


Uploading Auto Subroutine: Perl programming language has an Auto Subroutine Upload that allows users to auto load using Perl 5′s mechanism to define arbitrary semantics for anything that is undefined on your subroutine call.

Regular Expression Connectors: Perl lets you write expressions with embedded whitespace so that visitors can get better visibility.  The added extensibility mechanism is upwardly compatible with older regular expressions.

Many Unbundled Modules: With Perl network, you will also be able to find a large number of plug and play modules.

Compliable: With its compliable capability, you can generate portable byte codes even though you do not have a fully functional Perl-to-C compiler.

Lexical Scoping: Lexical Scope has similar variables like in the C programming language but more efficient and can provide better programming for your hosting.

RUBY:

Ruby is a reflective, general purpose object-oriented programming language. It supports multiple programming models that are functional, imperative, object oriented and reflective.

Its system is dynamic and memory management is automatic. Hence is similar in many respects with Perl, python etc.

It is said that ruby is very simple in appearance, but is very complex inside just like our human body. It’s a flexible language as it allows changes in its part.

Advantages of Ruby:

It is an interpreted scripting language. It’s a pure object oriented language.

It is very easy to learn. There are no variable declarations and it has very easy syntax.

Its developers also have access to powerful Ruby gems.

It has built-in support for complex and rational numbers.

It has a custom dispatch behavior.

It has dynamic alteration and reflection of objects to facilitate met programming.

It has native threads and co-operative fibers in its language.

Ruby is highly portable.

JAVA:

Java is a programming language developed as a core part of Sun Microsystems. This language has its syntax from C and C++. It is concurrent, general-purpose, class-based, object-oriented language. It makes available the code that runs on one platform and does not need to be changed to run on another. It is one of the most popular used languages.

Portability is one of the most important characteristic of Java. For this java bytecode is used in compilation with Java language. End users usually use a Java Runtime Environment installed on their own machine for standalone Java applications.

Advantages of JAVA:

Java language is very useful for scientists as they require OS whose code can be exchanged without requiring rewrites and recompilation that saves time and effort.

Java is simple and object-oriented. It is focused on creating and manipulating objects.

It is platform independent. It has ability to move easily from one system to another.

Java helps several computers on a network working together. It makes distributed computing easy.

Writing network programs is very simple and easy in Java. It is like sending and receiving data to and from a file.

Java is interpreted so that the Java programs run easily. The programs are compiled into Java Virtual Machine code called byte code. With Java, the program need to be compiled once and the byte code can run on any platform.

It is one of the primary programming languages to consider security as part of its design.

Java is robust means reliable which no programming language assures to be.

It is multithreaded that enables it to perform several tasks within a program.
