This document describes SODA, a tool that supports the detection of SOA (service-oriented architecture) antipatterns. The tool uses a three step approach: 1) specifying antipatterns, 2) generating detection algorithms, and 3) detecting antipatterns. It is built on the SOFA framework which allows for static and dynamic metric computation and rule specification. The SODA tool provides a graphical user interface for importing services, detecting antipatterns, and visualizing detection results. It aims to help identify common poor solutions known as antipatterns that can hinder maintenance and evolution of service-based systems.

- 2. Problem Context (1/2) Service-based System Service Requester HTTP, SOAP, WSDL, UDDI, WS-Technologies Service Provider Service Based Systems (SBSs) evolve to fit new user requirements, execution contexts: - may degrade design and quality of service (QoS) - may cause the appearance of common poor solutions: Antipatterns - Antipatterns hinder the future maintenance and evolution of SBSs 2 Francis Palma, Specification and Detection of SOA Antipatterns
- 3. Problem Context (2/2) Tiny Service Multiservice Examples of SOA Antipatterns: Tiny Service: Small service with few methods which requires several coupled services to complete an abstraction. Multiservice: Implements a multitude of methods, is not easily reusable because of low cohesion of its methods, is often unavailable due to overload 3 Francis Palma, Specification and Detection of SOA Antipatterns
- 4. Introduction: Contribution With the goal to detect SOA Antipatterns in SBSs: - SODA (Service Oriented Detection for Antipatterns), a SODA Tool novel and innovative approach. - SOFA (Service Oriented Framework for Antipatterns), a SODA Approach framework, - to specify SOA antipatterns and detect them automatically - to perform static and dynamic analysis SOFA Framework - SODA tool to perform detection using a Graphical User Interface (GUI). 4 Francis Palma, Specification and Detection of SOA Antipatterns

- 8. SODA Tool: Principal Features - Direct import of an SBS as a Jar package. - Straight forward detection interface for the users, handy both for beginners and experts. - Expose all the detection details, i.e., metric values, corresponding rule cards, textual descriptions of antipatterns etc. - Supports both well-known metric based and execution trace based analysis of SBSs. - Exposes all the execution traces, association rules generated from those traces, and relations among them, that is also useful to the users to better understand the SBS analyzed. 8 Francis Palma, Specification and Detection of SOA Antipatterns
