Our exam cram notes are a concise bundling of condensed notes of the complete exam blueprint. It is an ideal and handy document which provide you a quick view of the technological concepts related to the certification exam. Oracle database offers in-memory, NoSQL, and MySQL databases, as well as cost-optimized and high-performance versions of Oracle Database, the world's premier convergent, multi-model database management system. Customers may simplify relational database environments and minimize management tasks using Oracle Autonomous Database, which is accessible on-premises via Oracle Cloud@Customer or in the Oracle Cloud Infrastructure. The Database service provides Oracle Database cloud solutions that are self-managed and co-managed. Autonomous databases are fully managed, pre-configured systems that can handle transaction processing or data warehouse workloads. Bare metal, virtual machine, and Exadata DB systems that you may modify with the resources and settings that match your needs are examples of co-managed solutions. You may swiftly set up a self-contained database or a co-managed database system. Oracle owns and oversees the infrastructure, although you have full access to the capabilities and operations of the database.

This interactive study guide will support candidates in developing fundamental knowledge and understanding of data management, systems analysis and design, information flow within organisations, and the impact of emerging trends in information technology. It explains key concepts within the Information Systems module and helps candidates prepare for their exams, including explainer videos, interactive questions and skills challenges aligned to the syllabus and with industry practice. Having completed the design of your information system to meet your customer needs, the next stage is building it and letting others use the system. The Chapter 9 "Develop and deploy" covers the techniques and processes to be aware of when programming the code, testing the system, how to plan the release to stakeholders and how to maintain/improve the system going forward. Software testing is a critical part of developing software. It ensures the quality of the solution or application, making sure that it does the jobs that the customer has asked for.

This book is intended for developers working on applications that use a database server. The book speci cally addresses the PostgreSQL RDBMS: it actually is the world’s most advanced Open Source database, just like it says in the tagline on the official website. By the end of this book you’ll know why, and you’ll agree! I wanted to write this book af er having worked with many customers who were making use of only a fraction of what SQL and PostgreSQL are capable of delivering. In most cases, developers I met with didn’t know what’s possible to achieve in SQL. As soon as they realized — or more exactly, as soon as they were shown what’s possible to achieve —, replacing hundreds of lines of application code with a small and e cient SQL query, then in some cases they would nonetheless not know how to integrate a raw SQL query in their code base. The introduction of this book intends to convince application developers such as you, dear reader, that there’s more to SQL than you might think. It begins with a very simple data set and simple enough queries, that we compare to their equivalent Python code. Then we expand from there with a very important trick that’s not well known, and a pretty advanced variation of it. A simple Python application is introduced as a practical example illustrating the different answers provided. In particular, this part insists on when to use SQL to implement business logic.

The ability to produce visualizations has become critical, increasingly sought-after. Data visualization simplifies the process of analyzing data by presenting it in a format that's easier for human brains to understand. Since our eyes are more drawn to colors and patterns than words and numbers, this tool helps communicate information much faster and efficiently using graphical representations such as charts, tables, and maps. For example, an organization can represent its sales data with a map on top of using words and numbers. This visual map, color-coded based on the sales numbers, would help people understand how these sales increase or decrease or how the trend moves over a certain period. Data visualization is a helpful tool for every field in which data plays an important role: industries ranging from marketing to finance to tech. As a result, the ability to produce visualizations has become an important, increasingly sought-after skill for coding in today’s data analysis. This skill has also led to the rise of visualization tools, such as PowerBI, Tableau, and Looker. This book introduces the basic concepts behind visualizations and provides examples of each in Tableau. Tableau offers step-by-step tutorials on how to create each visualization.

Evolving technological advances in Artificial Intelligence-empowered Software present significant potential to lead e-Government towards more collective efforts, exchange of experiences on best practices both at national and international levels and dissemination of secluded administrative knowledge. In this book, novel semantic web-based and linked open data-based approaches are developed for the modelling and management of the huge volume of administrative data and the procedures followed by public sector bodies and for the production and management of relevant administrative knowledge. Knowledge in Semantic Web is in the form of triplets RDF, to which specific languages are focused. Their main object is the recovery of results upon submission of tailored questions in the form of triplets. Such languages are RQL and SPARQL.

Mathematical Methods in Data Science introduces a new approach based on network analysis to integrate Big Data into the framework of ordinary and partial differential equations for data analysis and prediction. The mathematics is accompanied with examples and problems arising in Data Science to demonstrate advanced mathematics, in particular, data-driven differential equations used. Chapters also cover network analysis, ordinary and partial differential equations based on recent published and unpublished results. Finally, the book introduces a new approach based on network analysis to integrate Big Data into the framework of ordinary and partial differential equations for data analysis and prediction. There are a number of books on mathematical methods in Data Science. Currently, all these related books primarily focus on linear algebra, optimization and statistical methods. However, network analysis, ordinary and partial differential equation models play an increasingly important role in Data Science.
