4. Concept and Specification Name Goal Actor Pre-Condition Post-Condition Post-Condition Special Case Normal Case in Register Secondary Information Structure The tenant operator registeres a secondary information structure and associates it with the specified source and target main information structure. Tenant Operator The tenant operator has the permissions in the service unit contingent, has registered a source and target data source, has registered a source and target main information structure, and the source and target datasources are NoSQL databases. The source and target secondary information structure meta-data are registered successfully, and associated with the specified source and target main information structure. Source and target secondary information structure are not registered, and are not associated with the specified source and target main information structure. 1. The tenant operator selects the service assembly to which the source data source is already associated. 2. The tenant operator selects the source and target data source to which the main information structure are associated. 3. The tenant operator selects the source and target main information structure to which the secondary information structure is associated. 4. The source and target secondary information structure are registered and associated with their source and target main information structure. Special Cases 1a. The service assembly does not exist. a) The system shows an error message and aborts. 2a. The source or target data source does not exist. a) The system shows an error message and aborts. 2b. The source and target data source is a MySQL database. a) The system shows an error message and aborts. 3a. The main source or target information structure does not exist. a) The system shows an error message and aborts. 4a. The secondary source or target information structure already exists. a) The system shows an error message and aborts. Table 4.4.: Description of Use Case Register Secondary Information Structure. 46
4.7. Web Service Interface 4.7. Web Service Interface The system must provide an interface with a set of operations to allow both the tenants and the Cloud Data Migration Application to interact with the system and configure the connections between the single physical consumer endpoint and the multiple provider endpoints. 4.8. Non-functional Requirements In this section we list and describe the non-functional requirements our system must fulfill. The non-functional requirements described in this thesis are independent from the ones satisfied by the Cloud data store providers, which are specified in the Service Level Agreement between the Cloud provider and the user. 4.8.1. Security Securing the tenant context information in our system is one of the main requirements we must fulfill. Tenant context in our system does not only contains tenant configuration data, but also contains the necessary meta-data from the backend data sources, which include the databases schemas and its access credentials. In order to ensure confidentiality and integrity of the data migrated to the Cloud, tenant configuration data must be visible only to the system, and not transferred to third parties through the Web or Web service interface. 4.8.2. Backward Compatibility In this diploma thesis we must face to two architectural tendencies in ServiceMix-mt: OSGibased components and JBI-based components. Backward compatibility with the multi-tenant JBI components developed in [Sá12], [Muh12], and [Ess11] must be ensured. At the same time we must build the new components following the OSGi tendency. Compatibility with non multi-tenant aware endpoint configurations must be ensured in the system. In ServiceMix-mt we extend existing components, e.g. ServiceMix-http-mt, ServiceMix-camel-mt, JDBCCdasmix, etc., and deploy them as custom components. By deploying the extended components as separate custom components, we avoid conflicts with the non multi-tenant aware components ServiceMix is shipped with, e.g. ServiceMix-http [ASM], ServiceMix-camel [ASM], Camel-jdbc [Thec], etc. Configuration of non multi-tenant aware endpoints is still supported in ServiceMix-mt. 47
