Scalability of Mobile Cloud Storage

<span>Today, there are high demands on Mobile Cloud Storage (MCS) services that need to manage the increasing number of works with stable performance. This situation brings a challenge for data management systems because when the number of works increased MCS needs to manage the data wisely to avoid latency occur. If latency occurs it will slow down the data performance and it should avoid that problem when using MCS. Moreover, MCS should provide users access to data faster and correctly. Hence, the research focuses on the scalability of mobile cloud data storage management, which is study the scalable on how deep the data folder itself that increase the number of works.</span>

Selecting and using faculty data management software systems

Purpose The purpose of this paper is to determine which software systems business school administrators use to support accreditation efforts and how administrators select and use these systems. This study also provides best practice suggestions from institutions using faculty data management systems to support accreditation efforts. Design/methodology/approach This study used a sequential explanatory design using an internet-based survey for business school administrators involved with accreditation reporting with follow-up interviews with survey respondents. Findings There are four major software vendors that most respondents use for managing reporting of faculty research activity and sufficiency. The location of the school appears to influence the system selected. For assurance of learning reporting, most schools used an in-house or manual system. Respondents highlighted the importance of doing a thorough needs analysis before selecting a system. Research limitations/implications Although respondents were geographically diverse, having a larger sample with schools in developing regions would provide greater generalizability of results. Practical implications This study gives business school leaders a comprehensive overview of the business schools’ data management systems, criteria used in system selection and best practices for system selection and implementation, faculty engagement and ongoing maintenance. Originality/value This study addresses the limited attention given to resources and best practices for selecting and implementing faculty data management software for accreditation in the academic and industry literature despite the significant investment of resources for schools and the importance such systems play in a successful accreditation effort.

Database Theory Column Report on PODS 2021

The 40th edition of the ACM SIGMOD-SIGACT-SIGAI Symposium on Principles of Database Systems (PODS) was held from June 20 to June 25, 2021, in Xi'an, Shaanxi, China. Due to the COVID-19 pandemic, it was organized in hybrid mode, with a local event primarily targeting the Chinese data management community and as a virtual (on- line) conference for the international community. As in previous years, the symposium was held jointly with the ACM International Conference on Management of Data (SIGMOD). PODS focuses on theoretical aspects of data management systems, and the co-location with SIGMOD stimulates interaction between theory-oriented and system-oriented research.

Cross-chain deals and adversarial commerce

Modern distributed data management systems face a new challenge: how can autonomous, mutually distrusting parties cooperate safely and effectively? Addressing this challenge brings up familiar questions from classical distributed systems: how to combine multiple steps into a single atomic action, how to recover from failures, and how to synchronize concurrent access to data. Nevertheless, each of these issues requires rethinking when participants are autonomous and potentially adversarial. We propose the notion of a cross-chain deal, a new way to structure complex distributed computations that manage assets in an adversarial setting. Deals are inspired by classical atomic transactions, but are necessarily different, in important ways, to accommodate the decentralized and untrusting nature of the exchange. We describe novel safety and liveness properties, along with two alternative protocols for implementing cross-chain deals in a system of independent blockchain ledgers. One protocol, based on synchronous communication, is fully decentralized, while the other, based on semi-synchronous communication, requires a globally shared ledger. We also prove that some degree of centralization is required in the semi-synchronous communication model.

ByShard

The emergence of blockchains has fueled the development of resilient systems that can deal with Byzantine failures due to crashes, bugs, or even malicious behavior. Recently, we have also seen the exploration of sharding in these resilient systems, this to provide the scalability required by very large data-based applications. Unfortunately, current sharded resilient systems all use system-specific specialized approaches toward sharding that do not provide the flexibility of traditional sharded data management systems. To improve on this situation, we fundamentally look at the design of sharded resilient systems. We do so by introducing BYSHARD, a unifying framework for the study of sharded resilient systems. Within this framework, we show how two-phase commit and two-phase locking ---two techniques central to providing atomicity and isolation in traditional sharded databases---can be implemented efficiently in a Byzantine environment, this with a minimal usage of costly Byzantine resilient primitives. Based on these techniques, we propose eighteen multi-shard transaction processing protocols. Finally, we practically evaluate these protocols and show that each protocol supports high transaction throughput and provides scalability while each striking its own trade-off between throughput, isolation level, latency , and abort rate. As such, our work provides a strong foundation for the development of ACID-compliant general-purpose and flexible sharded resilient data management systems.

CAPABILITIES OF THE SYSTEM «1C: ENTERPRISE» AND GEOSPATIAL SOLUTIONS IN THE FIELD OF SPATIAL DATA MANAGEMENT

The article presents the ways integrating the "1C:Enterprise" software with various application solutions, including geoinformation systems. The purpose of the study is to consider various ways of interaction between "1C:Enterprise" and GIS systems. Various protocols that facilitate integration with such systems, as Open Data Protocol (OData), Simple Object Access Protocol (SOAP), as well as a mechanism for supporting Web-services built into the "1C:Enterprise" platform are considered. Methods of representation of spatial data are given. A functional model of data integration is developed and built on the example of interaction with a fairly common geographic information system ESRI ArcGIS Online. A practical application of the integration of the software "1C:Enterprise" and geospatial data management systems is regarded.

Not every universities, including the International Women's University, are able to managedata optimally. The objectives of this study are to describe the current research and PKM datamanagement system at International Women University, to build a research and PKM datamanagement system at International Women University, and to conduct testing and implementationof research and PKM data management systems at the International Women University that havebeen created. The method used is descriptive-action, which first describes the entire system, thenanalyzes the shortcomings and weaknesses that occur and then takes action accompanied bysolutions to solve it. The system that will be built later is expected to be an enabler in the managementof Research and PKM activities for lecturers at the International Women University. In addition, thissystem is also expected to become an embryo for the creation of other systems so that the International Women University becomes a modern university based on CBIS (Computer Based InformationSystem).
