Benefit from our experience in software architecture

A clear separation drying into different layers reduces the complexity of dependencies in a system. The type and number of layers is individually depending on your requiements and your IT landscape. You can frequently find the following layers in distributed systems:

• • presentation
  • control
  • application
  • data access
  • data management

For data exchange with the database we avoid direct access to the DBMS (database management system). With object-oriented programming, an object-relational mapping (ORM) is necessary in the data access layer that is implemented by means of an ORM framework.

Web development with ASP.NET, HTML5, CSS3 and JavaScript

Today users mostly use more than one device – in addition to the desktop PC or laptop also smartphones or tablets are applied. Therfore, cross-platform development becomes increasingly important to make applications future-proof.

Modern web browsers are an all powerful platform. Whether Edge, Chrome, Safari or Firefox: The browsers have evolved into a powerful operating environment.

The basis of the programming language is JavaScript and Typescript. With ECMAScript 2015 JavaScript has reached a good and modern standard. With TypeScript, Microsoft offers an alternative that enjoys increasing popularity.

The secret of successful web-based software development is about three letters: SPA. The Single Page Applications are in a way the Smart Client for the browser. After the application start, the client logic takes place in the browser. The communication with the server is done via JSON over HTTPS with Web APIs or push services.
