Abstract: Embodiments maintain a data pool that includes heterogeneous data sets, and receiving a first data batch of a data set from a data source into the data pool. Embodiments determine a current state of the data set based on a data set state diagram including a plurality of data set states, and identify a condition of the first data batch. Embodiments further set a data batch state for the first data batch, based on a data batch state diagram, and update the data batch state of a prior data batch received before the first data batch, based on the condition of the first data batch. Embodiments additionally transition the data set state diagram, based on the condition of the first data batch, to an updated data set state. Embodiments maintain a data state repository storing the data set state for each of the plurality of heterogeneous data sets.

Abstract: Embodiments of the system in include a memory that stores a metamodel including a plurality of predefined characteristics for data sets. A data repository stores a plurality of heterogeneous data sets, each of the plurality of data sets comprising a plurality of data batches received over time. An interface receives a new data set for storage into the data repository, and data health reasoner to retrieve the stored metamodel from the memory, the stored metamodel including a plurality of predefined characteristics. The data health reasoner determines measured values of a subset of the plurality of predefined characteristics identified based on the stored metamodel, and determines a set of data health metrics for the data set based on the measured values of the subset of the set of the predefined characteristics. The data health reasoner formulates a plurality of data validation assertions for the data set and apply the plurality of data validation assertions to each instance of the data set.

Abstract: Embodiments of the system in includes data set analytics to identify one or more dataset utilized by a workflow. The data set analytics identifies upstream data sets referenced by the data sets utilized by the workflow. The set of all data sets relevant to the workflow are considered applicable data sets, and are analyzed. The data set analytics determines a usage pattern of each of the applicable data sets by the workflow, and identifies one or more data quality assertions for each of the applicable of data sets based on the usage pattern. The data set analytics further perform a quality evaluation of the applicable data sets by applying data quality assertions to the applicable data sets used by the workflow.

Abstract: A model-driven and QoS-aware infrastructure facilitates the scalable composition of Web services in highly dynamic environments. An exception management framework supports two modes of exception management for business processes, providing a novel policy-driven approach to exception management implemented in the system infrastructure. Exception management is implemented in the system infrastructure, with exception handling policies supplied by individual business processes. Using the exception management framework, developers define exception policies in a declarative manner. Before a business process is executed, the service composition middleware integrates the exception policies with normal business logic to generate a complete process schema. This policy driven-approach can significantly reduce the development time of business processes through its separation of the development of the business logic and the exception handling policies.

Abstract: An approach for conversion between database formats (e.g., from a relational database format to a hash table or a “big table” database format) based on user data access patterns in a networked computing environment is provided. A first set of database tables having a first format is identified based on a set of access patterns stored in a computer storage device. A second set of database tables having a second database format corresponding to the first set of database tables may then be provided (e.g., accessed, augmented, and/or generated). A mapping between the first set of database tables and the second set of database tables may then be created. A column set may then be generated based on at least one condition of the set of queries. The column set may then be used as a key for the second set of database tables.

Abstract: A mechanism for declarative service domain federation uses a declarative approach to both the visibility aspect and the management aspect of service domain federation. Instead of manually exporting services, that is, selecting individual services from source domains to be visible in the target domain, using the present system, a federation architect uses a federation console to specify federation intent. The federation intent may include federation rule, query-based service group, and quality-of-service (QoS) policy. Based on the declared federation intent, a planning engine resolves the individual services based on the group query, generates the service visibility configuration, and creates the necessary service proxies and/or mediation objects to satisfy the goal. At runtime, a service monitor collects the performance metrics of federated services and dynamically adjusts the mediation/proxy configurations to maintain the QoS objectives specified by the federation architect.

Abstract: One or more processors receive information regarding a program module that includes a description of a function, license terms, and non-functional properties of the program module. The license terms, the description of function, and the non-functional properties of the program module are identified, based on an analysis of the information. An object of interest of each license term of the license terms is determined, such that the object of interest is directed to a condition influencing license term compliance. Rules corresponding to compliance of the one or more license terms of the program module are determined, and the analyzed information of the program module is stored in a meta-model format organized into categories including the description of function, the one or more license terms, and the non-functional properties of the program module, utilizing standardized syntax and semantics.

A method includes generating a first set of configurations for a currently executing MapReduce job, wherein said set of configurations comprises job-level configurations and task-level configurations; dynamically modifying configurations associated with a mapper component and/or a reducer component associated with at least one ongoing map task and/or ongoing reduce task of the MapReduce job based on the generated first set of configurations; and deploying said first set of configurations to the mapper component and/or the reducer component associated with the MapReduce job.

Abstract: Embodiments of the present invention provide an approach to repair vulnerabilities (e.g., security vulnerabilities) in images (e.g., application images) in a networked computing environment (e.g., a cloud computing environment). Specifically, an image is checked for vulnerabilities using a database of known images and/or vulnerabilities. If a vulnerability is found, a flexible/elastic firewall is established around the image so as to isolate the vulnerability. Once the firewall has been put in place, the vulnerability can be repaired by a variety of means such as upgrading the image, quarantining the image, discarding the image, and/or generating a new image. Once the image has been repaired, the firewall can be removed.
