Unified Modeling Language

Unified Modeling Language

• Unified Modeling Language (UML) Grady Booch, Ivar Jacobson va Jim Rumbaugh tomonidan boshqa yetakchi metodologlar, dasturiy ta'minot sotuvchilari va ko'plab foydalanuvchilarning hissasi bilan birgalikda ishlab chiqilgan. UML ilovani modellashtirish tilini taqdim etadi:
• Jarayonni modellashtirish/ Use-casesni Talablarni tahlil qilish.
• Statik dizayn bilan Class va ob'ektni modellashtirish.
• Dinamik dizayn bilan ketma-ketlik, hamkorlik va faoliyat diagrammalari.
• Realtime tizimining dizayn modellari
• Tarqatish va joylashtirishni modellashtirish.

Tizimning rivojlanish bosqichlari

• Talablarni tahlil qilish
• Foydalanuvchilar tizimdan talab qiladigan funksiyalar
• Use-case modeli
• OO Tahlil
• Bog’lanishlar va Classlarni yaratish
• Class diagramma
• OO Dizayn
• Tahlil natijasi texnik yechimga aylandi
• Ketma-ketlik diagrammasi, holat diagrammasi, va boshqalar.
• Kodlash bosqichi uchun batafsil spetsifikatsiyalar natijalari
• Amalga oshirish (dasturlash/codlash)
• Modellar kodga aylantiriladi
• Tastlash
• Birlik testlari, integratsiya testlari, tizim testlari va qabul qilish testlari.

Use-Case Modellashtirish

• Use-Case Modellashtirishda tizim qora quti sifatida qaraladi, uning chegaralari tashqi ogohlantirishlarga nisbatan funksionalligi bilan belgilanadi..
• The actual description of the use-case is usually given in plain text. A popular notation promoted by UML is the stick figure notation.
• We will look into the details of text representation later. Both visual and text representation are needed for a complete view.
• A use-case model represents the use-case view of the system. A use-case view of a system may consist of many Use-case diagrams.
• An use-case diagram shows (the system), the actors, the use-cases and the relationship among them.
