   abstract = {Companies today have increasing amounts of data at their disposal, most of which is not used, leaving the data value unexploited. In order to leverage the data value, the data must be democratized, i.e., made available to the company employees. In this context, the use of enterprise data marketplaces, platforms for trading data within a company, are proposed. However, specifics of enterprise data marketplaces and how these can be implemented have not been investigated in literature so far. To shed light on these topics, we illustrate the characteristics of an enterprise data marketplace and highlight according marketplace requirements. We provide an enterprise data marketplace architecture, discuss how it integrates into a company's system landscape and present an enterprise data marketplace prototype. Finally, we examine organizational and technical challenges which arise when operating a marketplace in the enterprise context. In this paper, we thereby present the enterprise data marketplace as a distinct marketplace type and provide the basis for establishing it within a company.},

The process of making corporate data available to the majority of the company's employees is referred to as data democratization. In this work, we present the current state and challenges of data democratization in companies, derived from a comprehensive literature study and expert interviews we conducted with a manufacturer. In this context a data consumer's journey is presented that reflects the required steps, tool types and roles for finding, understanding and accessing data in addition to revealing three data democratization challenges. To address these challenges we propose the use of an enterprise data marketplace, a novel type of information system for sharing data within the company. We developed a prototype based on which a suitability assessment of a data marketplace yields an improved consumer journey and demonstrates that the marketplace addresses the data democratization challenges and consequently, shows that the marketplace is suited for realizing data democratization.},

   abstract = {Abstract. Metadata management is a crucial success factor for companies today, as for example, it enables exploiting data value fully or enables legal compliance. With the emergence of new concepts, such as the data lake, and new objectives, such as the enterprise-wide sharing of data, metadata management has evolved and now poses a renewed challenge for companies. In this context, we interviewed a globally active manufacturer to reveal how metadata management is implemented in practice today and what challenges companies are faced with and whether these constitute research gaps. As an outcome, we present the company{\^a}€™s metadata management goals and their corresponding solution approaches and challenges. An evaluation of the challenges through a literature and tool review yields three research gaps, which are concerned with the topics: (1) metadata management for data lakes, (2) categorizations and compositions of metadata management tools for comprehensive metadata management, and (3) the use of data marketplaces as metadata-driven exchange platforms within an enterprise. The gaps lay the groundwork for further research activities in the field of metadata management and the industry case represents a starting point for research to realign with real-world industry needs.},

Although various work on individual aspects of data lakes exists, there is no comprehensive data lake architecture yet. Concepts that describe themselves as a {\^a}€śdata lake architecture{\^a}€ť are only partial. In this work, we introduce the data lake architecture framework. It supports the definition of data lake architectures by defining nine architectural aspects, i.e., perspectives on a data lake, such as data storage or data modeling, and by exploring the interdependencies between these aspects. The included methodology helps to choose appropriate concepts to instantiate each aspect. To evaluate the framework, we use it to configure an exemplary data lake architecture for a real-world data lake implementation. This final assessment shows that our framework provides comprehensive guidance in the configuration of a data lake architecture.},

   abstract = {Data lakes are on the rise as data platforms for any kind of analytics, from data exploration to machine learning. They achieve the required flexibility by storing heterogeneous data in their raw format, and by avoiding the need for pre-defined use cases. However, storing only raw data is inefficient, as for many applications, the same data processing has to be applied repeatedly. To foster the reuse of processing steps, literature proposes to store data in different degrees of processing in addition to their raw format. To this end, data lakes are typically structured in zones. There exists various zone models, but they are varied, vague, and no assessments are given. It is unclear which of these zone models is applicable in a practical data lake implementation in enterprises. In this work, we assess existing zone models using requirements derived from multiple representative data analytics use cases of a real-world industry case. We identify the shortcomings of existing work and develop a zone reference model for enterprise-grade data lake management in a detailed manner. We assess the reference model's applicability through a prototypical implementation for a real-world enterprise data lake use case. This assessment shows that the zone reference model meets the requirements relevant in practice and is ready for industry use.},

   abstract = {Data lakes have become popular to enable organization-wide analytics on heterogeneous data from multiple sources. Data lakes store data in their raw format and are often characterized as schema-free. Nevertheless, it turned out that data still need to be modeled, as neglecting data modeling may lead to issues concerning e.g., quality and integration. In current research literature and industry practice, Data Vault is a popular modeling technique for structured data in data lakes. It promises a flexible, extensible data model that preserves data in their raw format. However, hardly any research or assessment exist on the practical usage of Data Vault for modeling data lakes. In this paper, we assess the Data Vault model{\^a}€™s suitability for the data lake context, present lessons learned, and investigate success factors for the use of Data Vault. Our discussion is based on the practical usage of Data Vault in a large, global manufacturer{\^a}€™s data lake and the insights gained in real-world analytics projects.},

   abstract = {The digital transformation leads to massive amounts of heterogeneous data challenging traditional data warehouse solutions in enterprises. In order to exploit these complex data for competitive advantages, the data lake recently emerged as a concept for more flexible and powerful data analytics. However, existing literature on data lakes is rather vague and incomplete, and the various realization approaches that have been proposed neither cover all aspects of data lakes nor do they provide a comprehensive design and realization strategy. Hence, enterprises face multiple challenges when building data lakes. To address these shortcomings, we investigate existing data lake literature and discuss various design and realization aspects for data lakes, such as governance or data models. Based on these insights, we identify challenges and research gaps concerning (1) data lake architecture, (2) data lake governance, and (3) a comprehensive strategy to realize data lakes. These challenges still need to be addressed to successfully leverage the data lake in practice.},

The data-driven factory enables agile, learning and human-centric manu-facturing and makes use of a novel IT architecture, the Stuttgart IT Architecture for Manufacturing (SITAM), overcoming the insufficiencies of the traditional information pyramid of manufacturing. We introduce the SITAM architecture and discuss its conceptual components with respect to service-oriented integration, ad-vanced analytics and mobile information provisioning in manufacturing. Moreover, for evaluation purposes, we present a prototypical implementation of the SITAM architecture as well as a real-world application sce-nario from the automotive industry to demonstrate the benefits of the data-driven factory.},

   abstract = {The automotive industry faces three major challenges – shortage of fossil fuels, politics of global warming and rising competition. In order to remain competitive companies have to develop more efficient and alternative fuel vehicles. Out of these challenges new cooperation models become inevitable. The development of complex products like automobiles claims skills of various disciplines e.g. engineering, IT. Furthermore, these skills are spread all over various companies within the supply chain and beyond. Hence, supporting IT systems for collaborative, innovative work is absolutely essential. Interdisciplinary and interorganizational development has new demands on information systems. These demands are not well analyzed at the moment and therefore, existing collaboration platforms cannot address them. In order to determine these new requirements and show the gap to existing collaboration platform we performed a case study. In this case study, we analyze the research campus “Active Research Environment for the Next Generation of Automobiles” (ARENA2036). It is a is a new cooperation form, where diverse partners from the industry, research institutes and universities elaborate collaboratively future topics in the field of production and light weight construction under “one single roof”. We focus on the special needs of the interdisciplinary, interorganizational partners. The requirements were polled by a questionnaire. About 80 percent of the active research workers in ARENA2036 answered the questionnaire. By the answers we can identify the special needs and also role profiles of the collaborators. The resulting role profiles specify the personal requirements. These are used for an evaluation of existing information platforms. The deficits between the offered features and the demands of the partners, as well as new technologies supporting the individual needs of users are the foundation for the information system concept for ARENA2036. In our findings we present a role-based view on requirements for the development of an information system for collaboration and cooperation. Based on these requirements we then develop a concept for mobile apps with focus on a role-based design.},

   abstract = {Mobile apps on smartphones and tablet PCs are more and more employed in enterprises to optimize business processes, e.g. by elimination of paper-based data collection. With respect to engineering, mobile apps provide a huge potential for increased flexibility and efficiency due to their anywhere and anytime characteristics, e.g., for product testing in the field. However, not every usage of mobile apps is beneficial from a business point of view and existing apps for engineering represent only rudimentary front-ends for stationary IT systems without an app-oriented redesign. Hence, there are three core challenges to leverage the potential of mobile apps in engineering: (1) identifying value-added app usage scenarios from a process point of view, (2) realizing a task-oriented and context-aware user interface design and (3) mastering technical obstacles at the app implementation. In this paper, we address these challenges by a case-oriented analysis of selected engineering processes in the automotive industry in order to identify engineering tasks suited for the usage of mobile apps. On this basis, we design corresponding engineering apps and analyze their business potentials. Moreover, we derive common technological challenges for the development of engineering apps, e.g. data synchronization aspects, and highlight further research issues.},

Hence, process improvement from a business point of view is not guaranteed. There is a methodological lack for a holistic analysis of business processes regarding mobile technology. For this purpose, we present an analysis framework, which comprises a systematic methodology to identify value-added usage scenarios of mobile technology in business processes with a special focus on mobile apps. The framework is based on multi-criteria analysis and portfolio analy- sis techniques and it is evaluated in a case-oriented investigation in the automotive industry.},

   abstract = {In this big data era, multitudes of data are generated and collected which contain the potential to gain new insights, e.g., for enhancing business models. To leverage this potential through, e.g., data science and analytics projects, the data must be made available. In this context, data marketplaces are used as platforms to facilitate the exchange and thus, the provisioning of data and data-related services. Data marketplaces are mainly studied for the exchange of data between organizations, i.e., as external data marketplaces. Yet, the data collected within a company also has the potential to provide valuable insights for this same company, for instance to optimize business processes. Studies indicate, however, that a significant amount of data within companies remains unused. In this sense, it is proposed to employ an Enterprise Data Marketplace, a platform to democratize data within a company among its employees. Specifics of the Enterprise Data Marketplace, how it can be implemented or how it makes data available throughout a variety of systems like data lakes has not been investigated in literature so far. Therefore, we present the characteristics and requirements of this kind of marketplace. We also distinguish it from other tools like data catalogs, provide a platform architecture and highlight how it integrates with the company{\^a}€™s system landscape. The presented concepts are demonstrated through an Enterprise Data Marketplace prototype and an experiment reveals that this marketplace significantly improves the data consumer workflows in terms of efficiency and complexity. This paper is based on several interdisciplinary works combining comprehensive research with practical experience from an industrial perspective. We therefore present the Enterprise Data Marketplace as a distinct marketplace type and provide the basis for establishing it within a company.},

   abstract = {The global conditions for manufacturing are rapidly changing towards shorter product life cycles, more complexity and more turbulence. The manufacturing industry must meet the demands of this shifting environment and the increased global competition by ensuring high product quality, continuous improvement of processes and increasingly flexible organization. Technological developments towards smart manufacturing create big industrial data which needs to be leveraged for competitive advantages. We present a novel IT architecture for data-driven manufacturing, the Stuttgart IT Architecture for Manufacturing (SITAM). It addresses the weaknesses of traditional manufacturing IT by providing IT systems integration, holistic data analytics and mobile information provisioning. The SITAM surpasses competing reference architectures for smart manufacturing because it has a strong focus on analytics and mobile integration of human workers into the smart production environment and because it includes concrete recommendations for technologies to implement it, thus filling a granularity gap between conceptual and case-based architectures. To illustrate the benefits of the SITAM{\^a}€™s prototypical implementation, we present an application scenario for value-added services in the automotive industry.},
