Geschäftslogik in der Datenbank Architektur und Objektorientierte PL/SQL-Programmierung Andriy Terletskyy Lead Database Architect Hamburg,

2 Geschäftslogik Geschäftslogik (engl. Business Logic, auch Anwendungslogik) ist ein abstrakter Begriff in der Softwaretechnik, der eine Abgrenzung der durch die Aufgabenstellung selbst motivierten Logik eines Softwaresystems von der technischen Implementierung zum Ziel hat. Allerdings ist der Begriff unscharf, da eine klare Trennung oft nicht möglich ist. Mehrfache BL-Umsetzung Datenbank Abhängigkeit Datenverarbeitungs- und Datenerfassungslogik Oracle EE ist mehr als eine Datenbank (Speicherort) SQL und PL/SQL Engine DBMS-Packages Object Types Type Mapping (Java&.NET) JPublisher, SQLData, STRUCT, ODP.NET

3 Datenbanken Architektur

4 Virtuelle ODBMS auf Basis RDBMS (DOAG Konferenz 2004)
Aufbau OO-ROWTYPE (ROWTYPE + DML, DEFAULT, TO_STRING, DBMS_OUTPUT- Methoden, PK/UK- Konstruktoren, ROW_LOCK) BO-Typen (Vererbung, Aggregation, Assoziation) Verwendung Methoden statt üblicher DML- Anweisungen Datennormalisierung über RDBMS PK/UK- Konstruktoren - ziehen referenziertes Objekt über relationale ID (DEREF- Analogon) Generator Java-Class PL/SQL-Wrapper DDL-Trigger mit asynchroner Queue

Analogon zur DEREF in ODBMS kann man mit dem FK eines Type den anderen Type instanzieren declare b wph.ROW_BOERSE; h wph.ROW_HANDELSSYSTEM; begin b := wph.ROW_BOERSE('194'); h := wph.ROW_HANDELSSYSTEM(b.HANDELSSYSTEM_ID); end;
