Integration Model of Academic Information Systems and Learning Management Systems with REST Web Services Using External Databases

ICT products like Academic Information Systems (AIS) and LMS are commonlyutilized in Indonesian universities. These two ICT tools will be of tremendous use tohigher education institutions in managing their academic business procedures. The twosystems are still not connected in many higher institutions, nevertheless, for examplewhen it comes to handling academic data. If the management and integration processis carried out conventionally, it will be challenging and inefficient due to the massivevolume of data and complexity of these two systems. Observing these issues, theresearcher plans to study the two REST-based Web Service systems' connection andmake use of the External Database functionality, which will be utilized to synchronizedata in real-time from AIS to E-Learning. It is hoped that the integration modelresulting from research can be a solution for integration between AIS and LMS and canbe implemented in many higher education institutions.

Integration Design of Academic Information Systems And Learning Management Systems Using Web Services Rest-Based External Database

ICT products that are widely used in universities in Indonesia are E-Learning with a Learning Management System (LMS) and Academic Information System (SIA). The existence of these two products from ICT will greatly assist the running of academic business processes in a higher education institution. Of course, if the two are well integrated, especially for managing existing academic data. However, in many tertiary institutions, the two systems are still not integrated, such as in managing academic data. The huge amount of data and the complexity of these two systems will make the management and integration process difficult and inefficient if done conventionally. Seeing these problems, the researcher intends to conduct research on the integration of the two REST-based Web Service systems and use the External Database feature which will be used to synchronize data from SIA to E-Learning in real time.

A Secure IoT Based Wireless Sensor Network Data Aggregation and Dissemination System

Cloud computing can greatly benefit web applications that have specific computation and storage requirements. With a scalable and adaptable design, the cloud is coupled with wireless sensor networks. Numerous application domains can be integrated directly with REST-based web services. An IP-based WSN testbed was used to develop a proof-of-concept REST API for remote data access. A user receives notifications via email or Twitter when monitoring data exceeds thresholds.

Hybrid Integration Model in Industry 4.0 for Lean Management (HIM)

In many large organizations, there is an Enterprise Resource Planning (ERP) system that needs to be integrated with a third-party system to provide real-time services to their customers. To achieve this, these organizations’(ERP) systems should have inbound (IB) and outbound (OB) integration capability through APIs. In this paper, we have proposed and implemented a Hybrid Integration Model (HIM) in Industry 4.0 for Lean Management. This research was implemented in an Airline Travel Company (ATC) in which an In-house ERP system is real-time-integrated (In-bound) with Global Distribution System (GDS) through API’s i-e, soap &rest-based web services for online ticketing as well other Miscellaneous facilities i-e (Auto SMS Email) using Horizontal Integration Model in Industry 4.0 and also integrated (Outbound) with 3rd party General Ledger (GL) system. Integrating an ERP system with GL is an automated business process that requires implementing API’s and developing automatic routines to move the data between ERP & GL Systems as per user requirements. Our proposed model is fully automated where no human intervention is involved while transferring data from ERP to GL and following all standards recommended by industry 4.0 for Lean Management.

The Pfizer Crystal Structure Database: An essential tool for structure‐based design at Pfizer

Pfizer's Crystal Structure Database (CSDB) is a key enabling technology that allows scientists on structure-based projects rapid access to Pfizer's vast library of in-house crystal structures, as well as a significant number of structures imported from the Protein Data Bank. In addition to capturing basic information such as the asymmetric unit coordinates, reflection data, and the like, CSDB employs a variety of automated methods to first ensure a standard level of annotations and error checking, and then to add significant value for design teams by processing the structures through a sequence of algorithms that prepares the structures for use in modeling. The structures are made available, both as the original asymmetric unit as submitted, as well as the final prepared structures, through REST-based web services that are consumed by several client desktop applications. The structures can be searched by keyword, sequence, submission date, ligand substructure and similarity search, and other common queries.

High business competition forces businesses to adapt to the needs of increasingly complex information systems. One of the market demands is the ease of conducting transactions that are mobile but still integrated with the company's overall information system. This challenge is also faced by a small business Kafa Photography engaged in the field of photography services for public. This business requires a data access system that is secure and supports multiple interfaces. Utilizing REST web service technology that can be used as a communication bridge between different access technologies can help the intended system integration. To improve the security of business process related information, it is necessary to add a cryptographic data mechanism. This research will develop a middleware utilizing the viginere cipher cryptographic method on REST-based web service services for the Kafa Photography business venture. The results of research in the form of web service architecture which are used as connectors between different applications, namely web and mobile that support business processes. To test the functionality and compatibility of the outcome, researcher use the Postman application tool and the prototype of mobile and web applications. The effectiveness and efficiency of derivative applications that use web services to improve services for Kafa Photography customers are not measured in this study.

Integration of REST-Based Web Service and Browser Extension for Instagram Spam Detection

In this paper, a REST-based Web Service developed in previous work was integrated with a newly developed browser extension that works in modern browser (Firefox and Google Chrome) using Greasemonkey. It uses previous collected datasets which comprised of 17.000 postings and comments from 10 Indonesian actresses whom followers are more than 10 million on Instagram. The performance of the developed web services has been evaluated and the average response time is 1678.133ms using AWS platform located in Ohio (US East 2). The proposed work is working as expected and in accuracy test, it has reached 63.125% in overall, 72% for non-stemmed data and 70% for stemmed data using 1000 test data with a processing time needed for classification is under 2s. The new extension works in Firefox and Chrome and it can utilize the web services to classify spam comments in Instagram.

Towards a Defense Mechanism Against REST-Based Web Service Attacks

Representational State Transfer (REST) web services has gained popular acceptance over the world-wide-web as a straightforward choice to the traditional or SOAP-based services. However, at present the REST-based service implementation does not have pre-defined security protection methods. In this paper, we present a defense mechanism against REST-based web service attacks called the REST-IDS, for a defense-in-depth network security in web service layer. REST-IDS is an intelligent mechanism that employs statistical approach to the state-of-the-art Text Mining-Based Anomaly Detection (TMAD) model to detect unknown novel vulnerabilities, which is sensitive to payload attacks.

Lynx is a web-based integrated systems biology platform that supports annotation and analysis of experimental data and generation of weighted hypotheses on molecular mechanisms contributing to human phenotypes and disorders of interest. Lynx has integrated multiple classes of biomedical data (genomic, proteomic, pathways, phenotypic, toxicogenomic, contextual and others) from various public databases as well as manually curated data from our group and collaborators (LynxKB). Lynx provides tools for gene list enrichment analysis using multiple functional annotations and network-based gene prioritization. Lynx provides access to the integrated database and the analytical tools via REST based Web Services (http://lynx.ci.uchicago.edu/webservices.html). This comprises data retrieval services for specific functional annotations, services to search across the complete LynxKB (powered by Lucene), and services to access the analytical tools built within the Lynx platform.

Defense Against REST-based Web Service Attacks for Enterprise Systems

In recent years, Representational State Transfer or REST-based Web Services have become popular for building Web systems. They have become an integral and critical part of information systems to facilitate and integrate the business processes across the enterprise. However, the simplicity of a REST-based implementation has caused the neglect of its systematic security threat analysis and design. One of the issues of systems built with REST services integration is their susceptibility to JSON input attacks. Such attacks could compromise the integrity of critical data in enterprise business processes. We analyze such a security issue in this paper. Some mechanisms used to secure Web sites and servers, such as encryption via HTTPS, static source code analysis, and input validation, can be integrated to defend against the attack.

Online Flood Information System

This paper implements a cyber-platform which visualizes and analyzes spatial patterns of flooding with a user-oriented spatial intelligence. The paper is organized from three perspectives: first, why representation and modeling of flooding data set is vital; second, how the design of flooding analysis involves spatial intelligence; third, why flooding analysis should be integrated into Cyber-infrastructure. The flood is one of the most common and devastative disasters. Flood disasters bring huge damages to the affected communities and beyond. Hence, a fast and effective flood information inquiry system is critical to reduce the loss. REST-based Web Service illustrates its great advantages in web map re-rendering, attribute information retrieving, and advanced GIS functions. This research introduces how to use REST-based Web Service to build a user-friendly online flood information inquiry system.

Towards Internet of Things (IOTS): Integration of Wireless Sensor Network to Cloud Services for Data Collection and Sharing

Cloud computing provides great benefits for applications hosted on the Web that also have special computational and storage requirements. This paper proposes an extensible and flexible architecture for integrating Wireless Sensor Networks with the Cloud. We have used REST based Web services as an interoperable application layer that can be directly integrated into other application domains for remote monitoring such as e-health care services, smart homes, or even vehicular area networks (VAN). For proof of concept, we have implemented a REST based Web services on an IP based low power WSN test bed, which enables data access from anywhere. The alert feature has also been implemented to notify users via email or tweets for monitoring data when they exceed values and events of interest.

Architecture for Health Information Systems Interoperability in Africa

Background and Purpose: Africa has seen a steady increase in the Information and Communication Technology (ICT) systems deployed in health care institutions. This uncoordinated mass migration to electronic health information systems in Africa has created an heterogeneous and complex computing environment where most of the deployed systems have technologies that are local, proprietary and insular. Furthermore, the infrastructure in Africa to facilitate the electronic exchange of information has a number of constraints. The infrastructure connectivity on which applications run is still segmented. Most parts of Africa lack the availability of a reliable connectivity infrastructure. In some cases, there is no connectivity at all. The realities of interoperability and re-usability problems have started to become more prominent in Africa as more systems are developed and deployed. It is not practical to either discard the existing systems or have only one system in place to solve this problem. The standards development work of the ISO TC 215 will have a major impact on the applications deployed across the continent once completed. Some African countries sit on these committees and it is important that the developers of architectures that will be deployed in Africa keep an eye on the work being done by the working groups of the TC 215. Another important aspect particular to an African environment is the connectivity issue. One has to be aware of the fact that the connections between the different systems are unreliable and subject to high segmentation levels. Architectures deployed need to be able to operate in a disconnected environment. Thirdly, technologies, particularly programming languages used to develop systems, need to be based on what the teaching industry, colleges and universities is providing to students in Africa. The core purpose of this work is interoperability of various IT assets in and outside a health institution and the connectivity of IT systems in the face of unreliable connectivity infrastructure in Africa. The goal of this research was to produce an outcome that can be generalised and applied to other cases in Africa. Methods: To solve the problem described above required the building of an artefact using specific software engineering methods. What systems that are in use today need, in additional to other standards issues, is an upgrade in order to expose them as web services and make them part of a Service Oriented Architecture (SOA), based on web services. Results: The three main theoretical contributions are a SOA Driven Disconnected Architecture (SOA-DDA), Runtime Dynamic Routing (RDR), and a methodology to enhance an application for future interoperability. The key practical contribution is an Application Programming Interface (API) design based on the Health Level 7 Reference Information Model (HL7 RIM) that is able to not only deal with the mediation or interoperability issues, but also operate in an unreliable connectivity environment and adjust to the ever changing and evolving health care standards. The API exposes REST based web services to the consumers of the services. It can be used to build systems from the ground up. It was constructed using rigorous documented processes to produce constructs, models, methods and an instantiation. Conclusions: The framework developed takes care of all the issues that need to be addressed in order to build a workable system.

FTR: Performance-Aware and Energy-Efficient Communication Protocol for Integrating Sensor Networks into the Internet

Integrating sensor networks into the Internet brings many advantages. For example, users can monitor or control the state of the sensors remotely without visiting the field. Some researchers have proposed methods using a REST-based web service or HTTP to establish communication between sensors and server via the Internet. Unfortunately, as we know, HTTP is a best-effort service. In some cases this means that if the number of sensors increases the end-to-end Quality of Service will decrease. The end-to-end network delay increases, as well as the failure rate of data sending caused by HTTP timeouts. In this paper, we propose Finite Time Response (FTR) HTTP as a communication protocol suitable for integrating sensor networks into the Internet. We have defined a cross-layer approach that coordinates between the application layer and the physical layer to control not only performance but also energy efficiency. The HTTP request-response delay measured at the application layer is used as the decision factor at the physical layer to control the active and sleep periods. We also propose a forced-sleep period as a control mechanism to guarantee average performance for all nodes. The experimental results have shown that FTR has the ability to maintain better performance, indicated by a lower average response time and a lower average timeout experience. Optimization is still needed to gain better performance and better energy efficiency while also considering the average value of the update time.

An Empirical Evaluation of Web System Access for Smartphone Clients

As smartphone clients are restricted in computational power and bandwidth, it is important to minimise the overhead of transmitted messages. This paper identifies and studies methods that reduce the amount of data being transferred via wireless links between a web service client and a web service. Measurements were performed in a real environment based on a web service prototype providing public transport information for the city of Hamburg in Germany, using actual wireless links with a mobile smartphone device. REST based web services using the data exchange formats JSON, XML and Fast Infoset were evaluated against the existing SOAP based web service.

Enabling successful Collaboration 2.0: A REST-based Web Service and Web 2.0 technology oriented information platform for collaborative product development

The competition of e-commerce is getting fiercer and customers are becoming more demanding. Customers navigate through the millions of products and services to fulfill their needs. Manufacturers and suppliers need to maintain full spectrum of related products and service to be attractive to customers. Focusing on producing their core competitive products with their proprietary capability becomes desirable yet unreachable. While organizations strive to focus on core competencies and becoming more flexible, an information platform which takes advantage of open, flexible Web 2.0 technologies is needed to increase the number of organizations involved in satisfying customer demand more effectively.In this paper, we describe a REST (Representational State Transfer)-based Web-Service and Web 2.0 technologies driven information platform for collaborative product development (WCPD). The WCPD aims to consolidate the once-fragmented world of customized product development into a more efficient platform of Collaboration 2.0, enabling products to be sourced and built more easily, quickly, inexpensively, and at higher quality levels. Users create their own profile to network with peers, build their reputation, promote their company, find collaborators, and buy and sell products.

A service infrastructure for the representation, discovery, distribution and evaluation of agricultural production standards for automated compliance control

Modern agricultural production is governed by a variety of production standards that restrict and guide farming practices. Controlling the compliance of farms to these standards is currently a considerable and expensive manual effort for several stakeholders of agriculture; an effort that could be alleviated with suitable information technology. This article identifies the requirements and proposes a design for a service infrastructure that transfers the production standards in a computer encoded and machine interpretable format between the stakeholders of modern agricultural production. These encoded production standards can then have an immediate benefit for farmers and providers of Farm Management Information Systems (FMIS), ultimately enabling automated compliance control with existing farm data. The functionality of the infrastructure is demonstrated with a precision fertilisation case, where compliance to several fertilisation restrictions is controlled and confirmed automatically. The proposed REST-based service infrastructure was found sufficient in fulfilling the identified requirements. Automated compliance control for a fair proportion of production standards, despite several technical challenges, can be reasonably achieved with existing technologies as a lightweight infrastructure of REST-based Web services.

A Novel WebService Architecture Based on REST

Aiming at the problem of tight coupling and interface complexity of WebService based on XML-RPC interactive model, this paper proposed the REST-based WebService, and gave out the design method of each part, including the design of restful Resource-Oriented Architecture, design of request and response interactive model and design of service discovery architecture based on semantic search. This research result was applied into an actual project, which indicated this WebService is loose coupling, interface uniform, portability, reliability and has good web-scale scalability features. Finally, an example is presented to illustrate this WebService architecture.

Web API for biology with a workflow navigation system

DNA Data Bank of Japan (DDBJ) provides Web-based systems for biological analysis, called Web APIs for biology (WABI). So far, we have developed over 20 SOAP services and several workflows that consist of a series of method invocations. In this article, we present newly developed services of WABI, that is, REST-based Web services, additional workflows and a workflow navigation system. Each Web service and workflow can be used as a complete service or a building block for programmers to construct more complex information processing systems. The workflow navigation system aims to help non-programming biologists perform analysis tasks by providing next applicable services on Web browsers according to the output of a previously selected service. With this function, users can apply multiple services consecutively only by following links without any programming or manual copy-and-paste operations on Web browsers. The listed services are determined automatically by the system referring to the dictionaries of service categories, the input/output types of services and HTML tags. WABI and the workflow navigation system are freely accessible at http://www.xml.nig.ac.jp/index.html and http://cyclamen.ddbj.nig.ac.jp/, respectively.

Past, Present, and Future of Web Service

World Wide Web was born as a means to provide information through the Internet. As a number of e-shopping sites are developed on the Internet, the Web provides not only information but also services with which users can interact to buy products. This paper describes the basic standards used in Web service; XML, SOAP, and WSDL, and how Web services are implemented on the Java-based platform Axis. It also mentions the REST-based Web service which gains more attention recently. Finally it forecasts the future of Web service from a viewpoint of Semantic Web.
