EXtensible Markup Language, XML, was designed as a markup language for structuring, storing and transporting data on the World Wide Web. The focus of XML is on data content; arbitrary markup is used to describe data. This versatile, self-describing data representation has established XML as the universal data format and the de facto standard for information exchange on the Web. This has gradually given rise to the need for efficient storage and querying of large XML repositories. To that end, we propose a new model for building a native XML store which is based on a generalisation of vertical decomposition. Nodes of a document satisfying the same label-path, are extracted and stored together in a single container, a Stripe. Stripes make use of a labelling scheme allowing us to maintain full structural information. Over this new representation, we introduce various evaluation techniques, which allow us to handle a large fragment of XPath 2.0. We also focus on the optimisation opportunities that arise from our decomposition model during any query evaluation phase. During query validation, we present an input minimisation process that exploits the proposed model for identifying input that is only relevant to the given query, in terms of Stripes. We also define query equivalence rules for query rewriting over our proposed model. Finally, during query optimisation, we deal with whether and under which circumstances certain evaluation algorithms can be replaced by others having lower I/O and/or CPU cost. We propose three storage schemes under our general decomposition technique. The schemes differ in the compression method imposed on the structural part of the XML document. The first storage scheme imposes no compression. The second storage scheme exploits structural regularities of the document to minimise storage and, thus, I/O cost during query evaluation. Finally, the third storage scheme performs structureagnostic compression of the document structure which results in minimised storage, regardless the actual XML structure. We experiment on XML repositories of varying size, recursion and structural regularity. We consider query input size, execution plan size and query response time as metrics for our experimental results. We process query workloads by applying each of the proposed optimisations in isolation and then all of their combinations. In addition, we apply the same execution pipeline for all proposed storage schemes. As a reference to our proposed query evaluation pipeline, we use the current state-of-the-art system for XML query processing. Our results demonstrate that: • Our proposed data model provides the infrastructure for efficiently selecting the parts of the document that are relevant to a given query. • The application of query rewriting, combined with input minimisation, reduces query input size as well as the number of physical operators used. In addition, when evaluation algorithms are specialised to the decomposition method, query response time is further reduced. • Query evaluation performance is largely affected by the storage schemes, which are closely related to the structural properties of the data. The achieved compression ratio greatly affects storage size and therefore, query response times.

This thesis deals with the in-store marketing and its application in the supermarket Billa ltd. The work is divided into the theoretical and practical part. The theoretical part deals with sales support, which includes in-store marketing. In the practical part I describe the current trends within in-store marketing and the merchandising problems there as well. The practical work is also dedicated to the description of the actual means of in-store marketing in the supermarket Billa ltd. The actual research work is carried out on the basis of survey and field survey of the supermarket. Using the obtained results and their comparison with the supermarket Albert are defined and I evaluated current trends in in-store marketing within the supermarket Billa ltd.

No / Loyalty, its antecedents, and its consequences have been considered extensively. Store loyalty, in particular e-store loyalty, has not, however, received the same level of attention despite the increase in the number of organisations that sell directly over the Internet. This paper focuses on two antecedents of e-store loyalty, perceived switching barriers and satisfaction, and the way in which they interact. It found that customers do not consider themselves loyal to the e-store they frequent despite being largely satisfied, that the impact of switching barriers varies at different levels of customer satisfaction, and that what customers consider to be a switching barrier differs at different levels of customer satisfaction.

The global fashion retail industry has been characterised by fierce competition for numerous years. Boutiques face increasing pressure to distinctly differentiate themselves from competing retail stores offering fashion merchandise, since customers are becoming ever more demanding as fashion evolves and new trends reach South African retail stores. Accordingly, marketers have to ensure customer satisfaction, build store loyalty, and stimulate repurchase intentions in the fashion retail industry in order to survive and prosper. For marketers to attract and retain customers, they have to adjust their marketing strategies and utilise various elements in the marketing mix to compete for customers’ attention, satisfy their retail experience needs, and encourage them to return. Shopping for clothes forms a significant part of many South African females’ lifestyles. Customers to whom fashion is important, have specific needs and wants and desire specific retail experiences. These customers are also becoming increasingly more sophisticated and individualistic, and therefore turn to small, speciality retailers such as boutiques, which they believe can accommodate them by providing unique and tailored retail experiences. Essentially, these customers do not merely purchase the retailer’s merchandise; they want to experience the store atmosphere the retailer offers. Therefore, it is important for boutiques to be aware of their store atmosphere which can offer customers a satisfying, consistent and sound retail experience. Customers who positively experience a retailer’s store atmosphere may feel more satisfied with the boutique, and may return to the retail store in the hope of receiving a similar retail experience. Once the customer returns to the same retail store, the possibility arises that the customer may become store loyal. As soon as the customer keeps on returning to the same retail store, the probability of repurchase intentions becomes real. That said, store atmosphere is considered to be a significant marketing tool, given that it provides boutiques with the power to manipulate a customer’s retail experience which could ultimately influence, customer satisfaction, store loyalty and repurchase intention. The primary objective of this research study is to investigate store atmosphere as a second-order construct model comprised from four sub-dimensions (factors) namely the retail store exterior, interior, layout and design and point-of-purchase and décoration in order to determine the interrelationships between these sub-dimensions (factors), customer satisfaction, store loyalty and repurchase intention in the fashion retail industry. In order to address this, a descriptive research design was followed and self-administered questionnaires were fielded amongst females, 18 years and older with an average monthly household net income of more than R14 000 (medium-to-high household income) who have bought items most recently from boutiques in Potchefstroom and Klerksdorp during the past six months. Judgemental, convenience and quota sampling methods were used to select the sampling units and sampling elements. A total of 361 questionnaires were ultimately analysed. With respect to the empirical results of this research study, respondents agreed the most that the exterior location of the boutique is convenient, the entrance to the boutique is inviting, the interior of the boutique is clean and that the temperature in the boutique is comfortable. Regarding the layout and design of the boutique, respondents agreed the most that the checkout and service points in the boutique are well placed and that all the spaces in the boutique are creatively utilised, as well as that the furnishings in the boutique are attractive. Finally, regarding the point-of-purchase and décoration of the boutique, respondents agreed the most that the pricing of the merchandise in the boutique is clearly visible and that the merchandise is well displayed. All the measurement scales measuring the sub-dimensions (factors) and constructs of this research study exhibit internal consistency reliability as well as content, construct and criterion validity. The standardised model results indicate that all statements included in the measurement model exhibit significant factor loadings above the recommended cut-off point, exhibiting a large effect in all instances, leading to the retention of all statements for further statistical analysis. With respect to the assessment of the structural model, the fit indices indicate an acceptable model fit. Based on the empirical results obtained from this research study, it became clear that store atmosphere has a large direct influence on customer satisfaction and store loyalty, albeit with no direct influence on repurchase intention. Both mediation relationships realised a medium indirect effect between store atmosphere and repurchase intention with customer satisfaction and store loyalty as mediators. The recommendations of this research study mainly focus on strategies to improve the store atmosphere of boutiques, since it positively influences customer satisfaction and store loyalty directly and repurchase intention indirectly. Limitations the researcher encountered were mainly related to budget and time constraints. Recommendations for future research include extending this research study to other Provinces of South Africa in order to determine the status quo in these Provinces and to determine whether statistical significant differences exist between respondents based upon demographic and geographic differences with respect to the constructs of this research study. / MCom (Marketing Management), North-West University, Potchefstroom Campus, 2015
