Presentation Transcript

  1. Application Architectures

  2. Application architectures • Starting point for the arch.design process • Design checklist • Way of organizing the work of the development team • Means of assessing components for reuse • Vocabulary for talking about types of applications

  3. Application architectures • Data-processing applications • Transaction-processing applications • Event-processing systems • Language-processing systems

  4. Data-processing applications • Data driven applications • Data is processed in batches • Mostly used in business applications that handle similar operations with large amount of data • Ex: accounting, billing, payroll

  5. Data-processing applications System Prn Input Process Output Database

  6. Transaction-processing applications • Database-centered applications that process user requests/updates of information • Most common types of interactive business systems • Ex: banking systems, e-commerce

  7. Transaction-processing applications I/O Processing Application Logic Transaction Manager Database

  8. Event-processing systems • Actions of the system depend on events in the system’s environment • Events can be the input of a command, change of values in variables • Ex: games, word processors, spreadsheets (see ex. of editing system pg 306)

  9. Language-processing systems • User intentions are expressed in a formal language • The language-processing system transforms this language into some internal form and then interprets this form • Ex: compilers, XML (see ex. of abstract architecture pg. 308)
