Enrich your skill set with Open SQL and CD5 views. SAP HANA (High-Performance Analytical Appliance) is an in-memory database engine from SAP that is used to analyze large data sets in real time that reside entirely in memory. Very crudely it is a Database System which totally changes the DBMS methodology and it can be deployable on premises or over cloud. Notice how SAP HANA has changed the world now. Whether you are a newbie or an old-hat, you can learn to design & build simple and advanced SAP HANA applications with ABAP/4 by using this comprehensive artifact. You can also enrich your skill sets with the use of new Open SQL enhancements and CD5 views, and integrate native SAP HANA objects. Use this detailed programming referral guide to develop database procedures and optimize your applications. An In-Memory database means all the data from source system is stored in a RAM memory. In a conventional Database system, all data is stored in hard disk. SAP HANA In-Memory Database wastes no time in loading the data from hard disk to RAM. | |

Practical SQL is an approachable and fast-paced guide to SQL (Structured Query Language), the standard programming language for defining, organizing, and exploring data in relational databases. Anthony DeBarros, a journalist and data analyst, focuses on using SQL to find the story within your data. The examples and code use the open-source database PostgreSQL and its companion pgAdmin interface, and the concepts you learn will apply to most database management systems, including MySQL, Oracle, SQLite, and others. | |

 Название: Business Analytics: Data Science for Business Problems
Автор: Walter R. Paczkowski
Издательство: Springer
Год: 2022
Страниц: 416
Язык: английский
Формат: pdf (true)
Размер: 14.0 MB
Practical in orientation, the volume offers illustrative case studies throughout and examples using Python in the context of Jupyter notebooks. Covered topics include demand measurement and forecasting, predictive modeling, pricing analytics, customer satisfaction assessment, market and advertising research, and new product development and research. This volume will be useful to business data analysts, data scientists, and market research professionals, as well as aspiring practitioners in business data analytics. It can also be used in colleges and universities offering courses and certifications in business data analytics, Data Science, and market research. In Machine Learning, the independent variables are called features. In regression analysis, an example of supervised learning, the goal is to estimate the unknown parameters based on the features to give the best estimate of the target. Since unsupervised learning has neither a target nor a set of parameters, the goal is to find clusters or groups of features using algorithms. | |

 Название: Practical Data Science for Information Professionals
Автор: David Stuart
Издательство: Facet Publishing
Год: 2020
Страниц: 201
Язык: английский
Формат: pdf (true)
Размер: 10.2 MB
The growing importance of Data Science, and the increasing role of information professionals in the management and use of data, are brought together in Practical Data Science for Information Professionals to provide a practical introduction specifically designed for information professionals. This book is not designed as an introduction to programming; it is an introduction to Data Science, for which programming is an extremely useful skill. As can be seen from the examples throughout the book, quite a lot can be achieved with relatively little programming knowledge by building on the work of others. All that is required is an understanding of a few basic concepts (variables, functions, loops). These are briefly covered in the Appendix, which gives simple examples for R and Python. R and Python are only two of the many hundreds of computer languages available. This book uses Python and R: Python because of its versatility and widespread use, and R because of the statistical packages that have been built for it. R and Python are very powerful, extensive languages with active sets of users, and the web is filled with tutorials for them. | |

 Название: Event- and Data-Centric Enterprise Risk-Adjusted Return Management: A Banking Practitioner’s Handbook
Автор: Kannan Subramanian R., Dr. Sudheesh Kumar Kattumannil
Издательство: Apress
Год: 2022
Страниц: 1112
Язык: английский
Формат: pdf (true)
Размер: 72.2 MB
The book provides guidance on the underlying knowledge areas of banking, enterprise risk management, enterprise architecture, technology, event management, processes, and Data Science. The first part of the book explains the current state of banking architecture and its limitations. After defining a target model, it explains an approach to determine the "gap" and the second part of the book guides banks on how to implement the enterprise risk-adjusted return model. Data virtualization (DV) can unify both structured and unstructured data in real-time to power the ERR model. DV has grown in its usage and is a critical part of modern enterprise data architectures. Data as a service (DaaS) is a business-centric service that delivers data assets on demand using a standard connectivity protocol in a predetermined, configurable format and frequency. DV can be exploited by enabling DaaS for data democratization and decision making. Machine learning (ML) and deep learning algorithms are finding more use cases in risk management and in general banking functions. Banks with large derivative portfolios have been early adopters as ML is good at managing non-linear relationships between explanatory variables and explained variables. ML can improve accuracy as be applied for a broader set of variables. | |
