A Survey of Mobile Transactions
TLDR
This paper analyzes and compares several contributions to mobile transactions and focuses on ACID properties support in proposals where transactions are completely or partially executed on mobile hosts. Expand
SStreaMWare: a service oriented middleware for heterogeneous sensor data management
TLDR
SStreaMWare is proposed, a service-oriented middleware for heterogeneous sensor data management that allows data representation of various types of sensors in a common generic way, and heterogeneity of sensor software is hidden by generic query services, which can be discovered and used dynamically. Expand
Semantic Cache Mechanism for Heterogeneous Web Querying
TLDR
This work develops a mechanism for efficient caching of Web queries and the answers received from heterogeneous Web providers and shows how the caching mechanism is implemented in the Knowledge Broker system. Expand
Data schema does matter, even in NoSQL systems!
TLDR
This paper presents an experiment performed using MongoDB along with several alternatives of data structuring and a set of queries having increasing complexity and introduces an analysis regarding the findings of such an experiment. Expand
Towards a change-aware process environment for system and software process
TLDR
The key strengths of this study are: first, the PDG makes hidden dependencies among process instances emerge at run-time; second, the process observer inside the BPMS allows to handle the change events in a timely manner. Expand
Towards Quality Analysis for Document Oriented Bases
TLDR
This work capitalizes on experiences with MongoDB, XML and software complexity metrics, and proposes a set of structural metrics for a JSON compatible schema abstraction intended to be used in decision criteria for schema analysis and design process. Expand
Transactional issues in sensor data management
TLDR
The relevance of ACID properties in sensor data management context is discussed, the isolation property is focused on and a concurrency control mechanism to support concurrent execution of continuous queries and update transactions on sensor properties is proposed. Expand
Toward Duration-Based, Constrained and Dynamic Event Types
TLDR
The model aims to provide a kind of events, with a more natural programming interface, making easier the mapping of real events into events supported by the DBMS. Expand
The ContextAct@A4H Real-Life Dataset of Daily-Living Activities - Activity Recognition Using Model Checking
TLDR
ContextAct@A4H is a new real-life dataset of daily living activities with rich context data and the experience of using temporal logic and model checking for activity recognition is presented. Expand
Top-k Context-Aware Queries on Streams
TLDR
This paper improves the existing work on data stream query-answering personalization by proposing a solution to express and handle contextual preferences together with a large variety of queries including one-shot and continuous queries. Expand
