The success and wellbeing of large organizations rely on the smooth functionality and operability of their software. Such qualities are largely affected by evolution events and changes, like software upgrades. In this paper, we are dealing with handling evolution events in data management systems. We consider a data-centric ecosystem that captures relational tables, views and queries (the latter are...
Dynamic software updating research efforts have mostly been focused on updating application code and in-memory state. As more and more applications use embedded databases for storage, dynamic updating solutions will have to support changes to embedded database schemas. The first step towards supporting dynamic updates to embedded database schemas is understanding how these schemas change-so far, schema...
Discrete manufacturing (DM) refers to produce products in non-sequential processes so as to respond to market and customer requirements quickly under limited lead-time. However, in shop-floor management, DM companies usually confront challenges such as information gaps between different manufacturing units, slow responsiveness to customer changes, and poor visualization. The main reasons are lacking...
The Orion Crew Exploration Vehicle is being designed with greater automation capabilities than any other crewed spacecraft in NASA's history. The Guidance, Navigation, and Control (GN&C) flight software architecture is designed to provide a flexible and evolvable framework that accommodates increasing levels of automation over time. Within the GN&C flight software, a data-driven approach is...
Database-as-a-service (DAAS) is a new model for data management, where a service provider offers customers software management functionalities as well as the use of expensive hardware. This service enables data integration and access on a large scale in cloud computing infrastructures. Addressing data privacy in DAAS is considered a significant issue for any organizational database. Due to the fact...
The conceptual structure of information software for fluorescence analysis, which will show the process of analysis and reduce the time required to select equipment.
In order to solve the serious problem of high energy consumption in large public buildings, lots of building energy monitoring systems (BEMS) have been established all over the whole country in recent years. The application of the Internet of Things (IoT) in building field will certainly raise the function of building auto control technology, and reform the monitoring control situation of building...
Multi-tenancy supporting becomes a basic characteristic of Software-as-a-Service (SaaS) operation. In multi-tenancy environment, tenant placement problem is critical for balance the database server workload. In this paper, we discuss how the cross-tenant data access affects the workload and how to optimize resource utilization in tenant placement process. This paper comes up with a SaaS tenant data...
The management of manufacturing recourses is discussed for realizing distributed networked manufacturing, the multi-goal evaluating model is put forward. The factors and process in networked manufacturing resources evaluating are given, and the service function and the system architecture of Internet of Things is set up. It is useful to actualize area networked manufacture.
Bioinformatics has developed some very sophisticated algorithms used for searching within the large amounts of data produced by sequencing projects. Introduced here is a method that leverages these algorithms for processing computer network data traffic to find and classify information in a way that avoids many of the operations that are required of more traditional methods of processing network data...
Virtual screening is a newly emerging method used in new drug research and development (R&D). The introduction of virtual screening immensely reduces R&D cycle and decreases R&D cost directly. Mass of chemical data used for virtual screening needs to be managed effectively in certain ways. We have developed the first release of ChemDataBase, but it only has the basic functions of chemical...
We introduce the concept of database proxies capable of mitigating the gap between two disjoint productivity-enhancing techniques: Component Based Software Engineering (CBSE) and Real-Time Database Management Systems (RTDBMS). The coexistence of the two techniques is neither obvious nor intuitive since CBSE and RTDBMS promotes opposing design goals, CBSE promotes encapsulation and decoupling of component...
This work presents an automatic method for identification of residential load profile in the Smart Grid context. Hence, in this research were used client/server software interfaces to transmit and receive data through the Internet. In this case, the residential consumers and utility were represented by client and server software, respectively. However, to consider all the stages of this method, a...
Automation systems engineering projects depend on contributions from several engineering disciplines. These contributions consist of complex artifacts like mechanical, electrical, and software components and plans, which get updated concurrently. While there are version management features in the software tools for each individual engineering discipline, there is very little work on version management...
The real-time monitoring of operational status in coal face can reduce the occurrence of risk effectively and prevent the further expansion of risk. This paper introduces a PC software in hydraulic supports control system based on VC++ through the investigation of coal face and the mathematical model of electric hydraulic and powered support control system. VC++ 6.0 was used to be the platform in...
In traditional method teachers are usually set in absolute major position in classroom teaching, while the Constructivist Teaching Theory emphasizes that the student must be the main body in courses. As a matter of fact, both of them are unilateral when applied on Access Database Programming Course teaching. The aim of this paper is to propose a new teaching mode based on Blending Learning Theory,...
Introduced was the development and implementation for the water pollution control technology database platform based on general management information system. The technology research and application demonstration of the system were developed, covering six fields such as lake water pollution treatment and ecological restoration, improvement of environment quality of urban water, drinking water safety,...
Accuracy and integrity is an important basis for vulnerability analysis and research. A vulnerability, which based on CVE standard, has more integrated properties, and collects several professional vulnerability databases' information, has been given, in order to ensure the accuracy and Authoritative of the source. Simultaneously, unifies the naming vulnerability, consummates the vulnerability information,...
Automatic, synchronous and of course reliable population of the condition databases is critical for the correct operation of the online selection as well as of the offline reconstruction and analysis of data. We will describe here the system put in place in the CMS experiment to automatize the processes to populate centrally the database and make condition data promptly available both online for the...
In real time systems, such as CMS Online Condition Database, monitoring and fast detecting errors is a very challenging task. To recover the system and to put it in a safe state requires spotting a faulty situation with strict timing constraints and a fast reaction. In the context of real time monitoring, this implies that the interval of time from when a faulty event occurs to when it is noticed...
