TL;DR: This tutorial outlines foundations and techniques to build database services based on the SaaS-paradigm, and discusses requirements from a programming perspective, shows different dimensions in the context of consistency and reliability, and describes different non-functional properties under the umbrella of Service-Level agreements (SLA).
Abstract: Modern Web or “Eternal-Beta” applications necessitate a flexible and easy-to-use data management platform that allows the evolutionary development of databases and applications. The classical approach of relational database systems following strictly the ACID properties has to be extended by an extensible and easy-to-use persistency layer with specialized DB features. Using the underlying concept of Software as a Service (SaaS) also enables an economic advantage based on the “economy of the scale“, where application and system environments only need to be provided once but can be used by thousands of users. Within this tutorial, we are looking at the current state-of-the-art from different perspectives. We outline foundations and techniques to build database services based on the SaaS-paradigm. We discuss requirements from a programming perspective, show different dimensions in the context of consistency and reliability, and also describe different non-functional properties under the umbrella of Service-Level agreements (SLA).

TL;DR: Both cloud service providers and legislative bodies need to acknowledge the impact that multi-tenancy can have on user privacy and act accordingly in regulatory steps and in encouraging a culture of adhering to common user standards.
Abstract: The purpose of this paper is to explore the challenges and complexity of multi-tenancy issues that have emerged though the development and adoption of cloud computing. The paper will focus specifically around cloud deployment and data storage, in particular relation to privacy concerns due to multi-tenancy. The reason for this lies with the identification of Software as a Service (SaaS) as the most likely adopted service model, particularly for those who are teleworking, as this relies on the service provider adopting a multi-tenancy environment within the data centre. The paper takes the perspective that, for both legal reasons and as part of shared obligation, it is necessary for users to recognise the need for common standards of policy and procedure. For example, this may be in levels of protection to prevent data protection and privacy laws being compromised. Both cloud service providers and legislative bodies need to acknowledge the impact that multi-tenancy can have on user privacy and act accordingly in regulatory steps and in encouraging a culture of adhering to common user standards. Such matters must be addressed at the earliest levels of growth in user demand to be optimally effective, especially when scalability is a fundamental driver for the adoption of cloud computing.

TL;DR: This paper discusses the latest information on cloud computing in a library context including literature review and vendor‐provided information and concludes that cloud computing is both a trend and technology to deliver software and hardware as a service, not as a product.
Abstract: Purpose – The purpose of this paper is to discuss the latest information on cloud computing in a library context.Design/methodology/approach – The paper adopts an investigative approach including literature review and vendor‐provided information.Findings – Cloud computing is both a trend and technology to deliver software and hardware as a service, not as a product. It involves a centralized data center, virtual server space, and secure transfer of data over the internet. The alleged advantages of cloud computing include low cost to own (CTO), agile updates, openness, zero initial investment, just to name a few. Lately library system vendors have begun to deliver cloud computing options. For instance, Ex Libris will release Alma in early 2012. It is an Integrated Library System with a discovery layer based on cloud computing. Amazon (Elastic Compute Cloud called Amazon EC2) and other vendors also offer virtual servers for cloud computing and charge customers by hours, usage, and capacity. If this trend co...

TL;DR: Novel upper-level ontology is proposed in order to model three fundamental constraints of manufacturing process planning: variety, time, and aggregation, derived from a three dimensional planning model developed during past research on computer-aided process planning.
Abstract: Distributed computer integrated manufacturing is increasingly adopting cloud computing, software-as-a-service (SaaS) and multi-agent systems as steps towards “design anywhere, build anywhere” strategy. In this scenario, ontologies not only serve as common message exchange structure among distributed agents but also provide reasoning capability to extract implicit knowledge from explicit information already stored in the knowledge base. Foundation ontologies (upper-level), comprised of most general concepts of a domain, provide a common semantic structure to the domain-level ontologies, which capture details of multi-disciplinary manufacturing knowledge. In this paper, novel upper-level ontology, called SIMPM (Semantically Integrated Manufacturing Planning Model), is proposed in order to model three fundamental constraints of manufacturing process planning: variety, time, and aggregation. The philosophical underpinning of the proposed ontology – presented as OWL-DL axioms – is derived from a three dimensional planning model, developed during our past research on computer-aided process planning. As part of the evaluation of SIMPM ontology, we first expound on the interoperability issues with other upper-level manufacturing ontologies. Next, we present a case study on process planning for prismatic part design. In this way, we demonstrate how the generic set of proposed axioms may be used to address various manufacturing process planning concerns, such as alternative manufacturing resources, the temporal order among operations and granularity in the details of a process plan.

TL;DR: A set of parameters which should be considered during a process of choosing one of ERP/MRP computing rank systems in SaaS technology for manufacturing company service are presented.
Abstract: Purpose: The main issue of this paper is present modern SaaS technology (Software as a Service) used in ERP/ MRP class systems designated for production companies from different SME lines. Design/methodology/approach: The paper presents assumptions and aims of implementation of SaaS systems on a background of classic computing system licences designated for company management. Findings: A present state of SaaS software development produced for manufacturing and enterprise resource planning as well as expected development directions of this technology in systems prepared for SME sector were introduced in this paper. Research limitations/implications: Further researches should be concentrated on particularizing specificity of requirements of production companies which want to change to outsourcing in systems working with SaaS mode. Practical implications: The paper presents a set of parameters which should be considered during a process of choosing one of ERP/MRP computing rank systems in SaaS technology for manufacturing company service. Originality/value: The paper might be useful for person dealing with modern technologies in ERP/MRP rank systems.
