Big data and polyglot solutionsKumaran Ramanujam

A polyglot solution uses multiple databases to perform operations and achieve results. It creates a hybrid data store combining an RDBMS and NoSQL tools for flexible and efficient data modeling. There are several approaches to implementing a polyglot solution, including using multiple "lanes" that separate data by domain into different databases, a polyglot mapper that handles multiple databases in parallel through mapping, a nested database where a primary database maps to a secondary one, or an omnipotent database that uses multiple relational and non-relational storage engines in parallel. The advantages of a polyglot solution include leveraging different databases' strengths and providing scalable, high performance query capabilities, while the disadvantages include increased complexity and imped

Multidimensional Data Analysis with Ruby (sample)Raimonds Simanovskis

This document discusses using Ruby to perform multidimensional data analysis on relational databases. It introduces Mondrian, an open-source OLAP engine that allows for multidimensional analysis on top of SQL databases using the MDX query language. A new Ruby gem called mondrian-olap will integrate Mondrian and provide a Ruby DSL and ActiveRecord-like query interface for defining OLAP schemas and performing analytical queries on relational data in a simpler way than SQL. Examples show how to write multidimensional queries in MDX and the Ruby interface to analyze sales data across dimensions like time, products, and customers.

Tutorial olap4jBorja A. Espejo García

OLAP4J is a Java API that provides OLAP analysis and uses the MDX query language. It allows querying of different cube servers like MSAS via XML/A and Mondrian. The key classes include OlapConnection, OlapStatement, CellSet, and Cell. MDX is similar to SQL but for OLAP databases, and allows filtering and retrieving data across dimensions like time and artists. Using OLAP4J and MDX, business intelligence tools can help identify market opportunities from large datasets and provide a competitive advantage.

Olap Cube Designh1m

This document discusses OLAP cubes, which provide a multi-dimensional representation of data. It describes cubes as containing facts and dimensions, and how dimensions can be organized hierarchically. It also outlines common operations on cubes like slicing, dicing, and drilling up and down hierarchies. Finally, it provides an overview of the process of building an OLAP cube in SQL Server Analysis Services.

OLAP Cubes in DatawarehousingPrithwis Mukerjee

MS SQL SERVER: Olap cubes and data miningDataminingTools Inc

OLAP cubes allow analysts to query aggregated data for decision making. Cubes are multidimensional databases containing dimensions like customer, product, and time. Processing a cube involves building dimension hierarchies and precalculating aggregations. Cubes can then be queried using MDX and browsed in tools like Excel. Data mining uses statistical techniques from fields like statistics and machine learning to analyze data, similar to how OLAP analyzes aggregated data. The data mining designer in SQL Server allows modifying mining structures and models, while the data mining wizard helps define new structures and models and partitions data into training and testing sets.

DocDokuPLM presentation - OW2Con 2015 Community Award winnerDocDoku

DocDoku: Using web technologies in a desktop application. OW2con'15, November...OW2

The DocdokuPLM is an open-source platform allowing its users to manage their product's lifecycle, from design to maintenance. The main application is built upon RequireJS and BackboneJS librairies for the front-end, and JEE for back-end. The GUI is quite complete, and may won't fit for all users involved in the process. This is especially the case for CAD designers who just need to commit their changes without having such a rich graphic interface. To answer this need, we developped a desktop application, interfacing our server with the CAD designer's file system : the DPLM. First, we developped a command line interface, which is very lightweight and really great for advanced users. However providing a GUI which could interface with the CLI and allow the user to manage multiple files upload at once was more than needed. Providing a consistent user experience across different platforms has been one of our challenges in the context of our application. The choice of a web framework was then a natural choice. But how could we get it run within a desktop application ? Node-Webkit brought us the ability to interact directly with the user's file system and embed the app in a webview, letting us the choice to use any web framework we wanted to use.

It allows processing data at the edge to save money by only sending essential data from devices. Edgent provides connectors for various data sources and sinks and can be used for IoT, embedded in application servers, and for monitoring machines. The edge refers to devices, gateways, and sensors at the network boundary that provide potential data. Edgent applications follow a common structure of getting a provider, creating a topology, composing processing graphs, and submitting it for execution.

Apache CouchDBMike Frampton

CouchDB is an open-source document-oriented NoSQL database that stores data in JSON format. It provides ACID support through multi-version concurrency control and a crash-only design that ensures data integrity even if the database or servers crash. CouchDB supports single node or clustered deployments and uses bidirectional replication to synchronize data across nodes. It prioritizes availability and partition tolerance according to the CAP theorem.

Designing Low-Latency Systems with Rust and ScyllaDB: An Architectural Deep DiveScyllaDB

Want to learn practical tips for designing systems that can scale efficiently without compromising speed? Join us for a workshop where we’ll address these challenges head-on and explore how to architect low-latency systems using Rust. During this free interactive workshop oriented for developers, engineers, and architects, we’ll cover how Rust’s unique language features and the Tokio async runtime enable high-performance application development. As you explore key principles of designing low-latency systems with Rust, you will learn how to: - Create and compile a real-world app with Rust - Connect the application to ScyllaDB (NoSQL data store) - Negotiate tradeoffs related to data modeling and querying - Manage and monitor the database for consistently low latencies

How analogue intelligence complements AIPaul Rowe

Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results. News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
