SW-Architektur Was ist das?

3

§  Klärung des Begriffs „Software-Architektur“

§  Die Architektur des Systems als faktische Eigenschaft (beschreibbar in einer Architektur-Dokumentation)

§  Jedes SW-System, hat eine Architektur

§  Gut oder schlecht (wie bewerten wir das?)

§  Geplant oder ungeplant

§  Die Tätigkeit, eine Software-Architektur zu entwickeln

§  Nicht jedes SW-Projekt kennt diese Tätigkeit (leider)

•  Bewertung von Software-Architektur

•  Architektur ist kein Selbstzweck

•  Architektur dient der Anwendungsentwicklung

•  Architektur richtet sich nach den Anforderungen

Zukunftsfähige SW-Architekturen Wie sehen die aus?

15

§  Anpassungsfähigkeit

§  nicht auf Vorrat bauen ...

§  ... aber so bauen, dass Änderungen möglich sind

§  fachlich: neue, geänderte Anforderungen

§  technisch: neue Technik, geänderte Umgebungen

§  Aber wie macht man das?

§  Systeme werden aus unterschiedlichsten Bestandteilen zusammengesetzt

§  Eigenentwicklung / zugeliefert

§  unterschiedliche Technik

§  Gibt es die Standard-Architektur?

§  Integration ist wichtig

§  Bestandteile des Systems

§  Schnittstellen zu anderen Systemen

§  Braucht jeder einen ESB?
