Horizontal Fragmentation

The database replication refers to distributing a database among multiple locations. There are three kinds of database replication system: snapshot, transactional and merge. The snapshot replication refers to the fragment of database items and distributing them to multi databases at once. An important goal in this paper is to experiment with a distributed database study the snapshot replication and examine the issues associated with it. In this work, the data from another database is used to increase availability and flexibility as well as provide the information exchange between databases. In this process, the data is infrequently updated at specified periods by copying and changing the data from the original database towards the subscriber database. The work of agents in this technology will do the most of the work to achieve the stated goal. The experimental results show that at both vertical and horizontal fragmentation, the proposed approach of replicating distributed database is efficient and the performance is significantly improved in terms of data transfer time, load sharing and update of database fragmentation. Hence the snapshot replication system is much schedulable and protective replication in business markets.   http://dx.doi.org/10.25130/tjps.23.2018.177

Distributed Database System

Allocation of data is one of the key design issues of distributed database. A major cost of query execution in a distributed database system is the data transfer cost from one site to another site. The allocation of fragments among the different sites over the network plays an important role in performance of the distributed database system. The main objective of a data allocation in distributed database is to place the data fragments at different sites in such a way, so that the total data transfer cost can be minimized while executing a set of queries. In this paper, a new biogeography-based optimization (BBO) algorithm has been used to allocate the fragments during the design of distributed database system. The goal of this paper is to design a fragments allocation algorithm, so that the total data transmission cost can be minimized. To show the performance of proposed algorithm, results of biogeography-based optimization algorithm for data allocation are compared with genetic algorithm.

With the developing of Distributed Database technology, fuzzy query of Distributed Database has been playing an important role in the information query. Raising query speed and precision ratio is always the main topic of information query. In this paper, a new type of information query system--Distributed Database system is designed with rough set theory and fuzzy set knowledge. A new information query method is advanced and the architecture of the system and its key algorithms are given. Main characteristic of the research achievement is that query algorithm’s time complexity decreases with the increase of amount of information and relates to the only amount of index words. Results show that it is an effective method with which a system for fuzzy query is implemented.

To successfully confront a disaster, it is necessary the coordinated and collaborative participation of multiple agencies related to public safety, which provide a response consistent with the requirements of emergency environment and all those affected. For this, is necessary the permanent information exchange between the involved agencies that allows to joint its efforts and to face the emergency of the best possible way. This article describes the interoperability platform architecture, which enables agencies involved in management of an emergency, exchange information using their own information systems and computer tools. The architecture core is inside its Shared Information Space, which manages it as a single storage entity, all information coming from the information systems integrated to the platform. It is founded on a non-relational distributed database and a P2P communications network, to share out the workload between all the platform nodes in order to award availability and scalability to the architecture.

AbstractData transfer has been forced to evolve as digital technologies are implemented throughout various aspects of the healthcare system. Despite the uniqueness of both the geography and the population of Queensland, information exchange and data communication has continued to follow this evolutionary trend. There have been a number of different health reforms designed to integrate digital innovations and allow critical data and information to be shared with the appropriate health professionals when necessary. Strict healthcare legislation has been navigated and to provide newly upgraded technologies and processes while maintaining privacy, confidentiality and security standards. A large portion of the digital revolution has been the implementation of the national run project, the My Health Record and the state run project, the Integrated Electronic Medical Record. Both are platforms that allow secure information exchange allowing patients to have improved quality of care. To maintain the steady progress, both the state and federal governments have developed strategies and visions to help provide guidance and direct for ongoing and future digital projects. They also outline areas that require further advancements to ensure Queensland is delivering equitable, high quality healthcare.

Abstract The authors of the article sought to answer the questions: do geography teachers feel a tie with their place of work, what is the strength of this relationship and what factors influence these declared ties with the place. A step towards knowing the answers is the declared subjective assessment of emotional relationships with such a place. To this end, surveys were conducted among geography teachers. Due to their profession, they are a social group having a wide range of influence on young people and their attitudes towards their local geographical environment. Organizational reasons (the ability to reach teachers of all schools through the information exchange platform between Board of Education and school heads – so-called the headmasters panel) decided to examine a selected group of respondents – geography teachers of the Silesian Voivodeship. Google questionnaire was used as an electronic form of data collection. The research was quantitative and only partly qualitative. The analysis of the obtained results gave an interesting view of the perception of teachers' relations with the place where their school is located – their place of work. Almost all respondents declared the existence of a territorial bond with their place of work. The workplace itself is an important factor in the formation and strength of these ties. The length of residence in a given place was also important, and its type (town or a village) and size were less important. For half of the surveyed teachers, it was difficult for them to indicate the distinguishing feature (symbol) of their place of work, regardless of whether they were inhabitants or commuters from elsewhere.

Successful information technology transfer requires effective communication and clear, concise information exchange. This paper, using the Louisiana econometric model as a case study, proposes a pictorial approach to present and manage complex factors essential to information technology transfer. The approach utilizes multi-layer entity-relationship diagrams to provide a meaningful framework for the entire forecasting process, provide clarity to ensure better model maintenance when changes in social/economic structures require reformulations, and provide a procedural and data dictionary for clear documentation. The pictorial approach is both intuitive and readable, capable of serving as a task management tool, a model implementation aid, and a system maintenance resource.

Changes Over Time

Companies are required by law to report all kinds of information to various public agencies. Since most public agencies are autonomous and define their information demands independent of each other, companies have to report information to various agencies in different ways. Accordingly, governments are initiating programs that aim to transform business-to government information exchange to reduce the administrative burden for companies and improve the accountability at the same time. Yet little research is available on the type of transformations needed and the role of the infrastructure. Drawing on a case study, this paper investigates the interplay between technical infrastructure and transformation. In this case study an information brokerage infrastructure based on the Extensible Business Reporting Language (XBRL) was developed providing a one stop shop for companies and public agencies. The case study shows that the infrastructure should be flexible enough to accommodate changes over time but stable enough to attract a large user-base. The increase in efficiency and effectiveness of information exchange processes requires extensive transformation from both public and private parties.

PurposeThis paper aims to represent the results of a case study to establish a building information model (BIM)-enabled workflow to capture and retrieve facility information to deliver integrated handover deliverables.Design/methodology/approachThe Building Handover Information Model (BHIM) framework proposed herein is contextualized given the Construction Operation Information Exchange (COBie) and the level of development schema. The process uses Autodesk Revit as the primary BIM-authoring tool and Dynamo as an add-in for extending Revit’s parametric functionality, BHIM validation, information retrieval and documentation in generating operation and maintenance (O&M) deliverables in the end-user requested format.FindingsGiven the criticality of semantics for model elements in the BHIM and for appropriate interoperability in BIM collaboration, each discipline should establish model development and exchange protocols that define the elements, geometrical and non-geometrical information requirements and acceptable software applications early in the design phase. In this case study, five information categories (location, specifications, warranty, maintenance instructions and Construction Specifications Institute MasterFormat division) were identified as critical for model elements in the BHIM for handover purposes.Originality/valueDesign- and construction-purposed BIM is a standard platform in collaborative architecture, engineering and construction practice, and the models are available for many recently constructed facilities. However, interoperability issues drastically restrict implementation of these models in building information handover and O&M. This study provides essential input regarding BIM exchange protocols and collaborative BIM libraries for handover purposes in collaborative BIM development.
