What is a functional requirement?
Vad är ett funktionellt krav?
De tjänster och funktioner som systemet ska tillhandahålla användaren. Exempel på funktionella krav på ett system är möjlighet att registrera en betalning, kunna skriva ut en faktura, beräkna ett resultat etc
What is a Non-functional requirement?
Vad är ett icke funktionellt krav?
Krav som inte beskriver något som någon/något vill göra i/med systemet. Till exempel krav på prestanda, tillgänglighet mm
«include» & riktning
Används när man alltid ska göra det relaterade användningsfallet. Andvänds när ett andvändningsfall inkludera funktionaliteten av ett annat användningsfall
Ritas som sträkade pilar,
include pilen är riktad mot det användningsfallet som innehåller den funktionalitet som allitd ska göras
«extend» & riktning
Används när man inte allid ska göra det relaterade användningsfallet. Används när ett användningsfall utökar ett annat användningsfall
Ritas som sträkade pilar,
extend pilen utgår från det användningsfall som eventuellet ska göras i samband med det relaterade användningsdaller
Domänmodell
Är en representation av verkliga konceptuella klasser, inte av programvarukomponenter.
Det som visas i en domänmodell är;
- Domänobjekt eller konceptuella klasser
- Associationer mellan konceptuella klasser
- Attribut för konceptuella klasser
Coupling / Koppling
Coupling är ett mått på hur sammanflätade olika moduler/komponenter är i ett mjukvarusystem (the linkage between modules). Låg coupling är bra.
Cohesion / Sammanhållning
Cohesion är ett mått på hur väl innehållet i en modul hänger ihop, hur fokuserad den är (the internal binding within a module). Hög cohesion är bra
