तीन स्तरीय / बहुस्तरीय आर्किटेक्चर (UI / Logic / DAO / Domain model) में, सेवाओं को संबंधित के रूप में माना जा सकता है व्यापार तर्क स्तर या क्या वे कुछ अलग के रूप में स्थित हैं?

आप शायद यह पाते हैं कि एक काफी सामान्य शब्द जैसे "सेवा" का अर्थ अलग-अलग लोगों के लिए अलग-अलग बात है।

मैं किसी सेवा के बारे में सोचता हूं जो एक उपयोगी कार्य (जैसे व्यवसाय प्रक्रिया) को कार्यान्वित करने के लिए व्यापारिक वस्तुओं (या अन्य सेवाओं) से अवगत कराया गया तर्क है। । तो, मेरे लिए, एक सेवा व्यवसाय लॉजिक परत का एक उपभोक्ता है (और संभवतः लॉगिंग जैसे समर्थन पहलुओं की)।
