Java – is one of the most efficient programming languages and a trademark of the company Sun Microsystems (Oracle since 2010). It is meant to be a simple, object-oriented, distributed and familiar programming language. In comparison to other object-oriented languages like C++ or C#, Java is simple and dynamic.
ASP.NET – (Active Server Pages .NET) is a server side technology from Microsoft for creating dynamic web sites, web applications and web services based on the Microsoft .NET Framework. ASP.NET is therefore not a programming language, but a bundle of techniques.
Ruby on Rails – briefly Rails, is an open source web application framework written in the Ruby programming language. It is based on the rules “Don’t Repeat Yourself” (DRY) and “convention over configuration”. These principles enable agile software development.
PHP – is a scripting language with a syntax similar to C and Perl that is used mainly for creating dynamic websites or web applications. PHP is distributed as free software under the PHP license. PHP is used on about 75% of all websites as server-side programming language and is therefore the most used language for creating web sites.
Oracle Database – (also Oracle Database Server) is a database management system software of the company Oracle. It can store relational and object-relational data. As a language you can use not only SQL but also Java.
DB2 – is a commercial relational database management system (RDBMS) from IBM. The compressed format of records in DB2 enables significant space savings on disk arrays with less processor usage.
PostgreSQL – is a free object-relational database management system. It allows complex queries with subqueries and maximum customization of the database size.
MySQL – is a relational database management system. It is available as open source software as well as a commercial enterprise version for different operating systems and forms the basis for many dynamic websites.
MongoDB – is a high-performance, schema-free, document-oriented open source database written in C++. As the database is document-oriented, it can manage collections of JSON-like documents. This lets many applications model data in a more natural way, as data can be nested in complex hierarchies while remaining queryable and indexable.
