RDBMS to Graphs
Relational databases were conceived to digitize paper forms and automate well-structured business processes, and still have their uses. But RDBMS cannot model or store data and its relationships without complexity, which means performance degrades with the increasing number and levels of data relationships and data size. Additionally, new types of data and data relationships require schema redesign that increases time to market.
A graph database like Neo4j naturally stores, manages, analyzes, and uses data within the context of connections meaning Neo4j provides faster query performance and vastly improved flexibility in handling complex hierarchies than SQL. Join this webinar to learn why companies are shifting away from RDBMS towards graphs to unlock the business value in their data relationships
Fast Focus: SQL Server Graph Database & Processing
Short presentation on the graph database and processing support in SQL Server 2017 (plus new stuff in 2019) as presented at Live 360! SQL Live
.NET RIA Services Architecture Overview
RIA Services focuses on simplifying n-tier application development by treating client and server as one logical application. It provides a prescriptive pattern called DomainService for encapsulating application logic on the server in a data-driven and stateless way. DomainService works with DomainContext on the client to provide a stateful view of bindable data through data binding and commanding. This unified approach works across multiple client platforms and data access technologies while providing benefits of n-tier architectures like testability and loose coupling.
PykQuery.js
PykQuery is a conceptual framework that help organise complexity around data-driven interactive single page apps.
Data Modeling with Neo4j
This presentation covers several aspects of modeling data and domains with a graph database like Neo4j. The graph data model allows high fidelity modeling. Using the first class relationships of the graph model allow to use much higher forms of normalization than you would use in a relational database.

DAS Slides: Data Architect vs. Data Engineer vs. Data Modeler
This document discusses the roles of data architect, data engineer, and data modeler. A data architect requires comprehensive experience and must work with both technical and business teams. Data engineers specialize in big data solutions using technologies like data lakes and warehouses. Data modelers translate business rules into data models and designs. Hiring good data modelers is important for projects.
Performance neo4j-versus (2)
Neo4J and MongoDB were evaluated for performance on social networking metrics. Network closure and assortativity had higher throughput than distance in Neo4J, since distance requires graph traversal while the others only require lookups. Embedded Java API outperformed other access methods due to eliminating network overhead. MongoDB was 10-100x slower than Neo4J RESTful and embedded versions for distance metric, which requires many index lookups that MongoDB handles less efficiently than Neo4J's relationship expander. Future work includes integrating social metrics into benchmark frameworks to better evaluate databases for complex graph operations.
RDBMS to Graph
Relational databases were conceived to digitize paper forms and automate well-structured business processes, and still have their uses. But RDBMS cannot model or store data and its relationships without complexity, which means performance degrades with the increasing number and levels of data relationships and data size.

ENHANCING THE PERFORMANCE OF E-COMMERCE SOLUTIONS BY FRIENDS RECOMMENDATION S...
In the past, selling needs brick and mortar store and it is limited to a local customer base. But today, ecommerce
websites make it easy for the customers around the world to shop by virtual store. Performance of ecommerce
websites depend not only the quality and price of the product but also the customer centric suggestions about the
product and services and retrieval speed of websites. There is more possibility to buy a product brand suggested by
friends or relatives than by viewing commends from unknown people. We can implement such a customer centric
approach using Neo4j database, which provides easy and fast retrieval of information based on multiple customer
attributes and relations than relational databases. Experiment shows the enhancement of performance in terms of
time and complexity
How do I Even Web App
The document provides guidance on building a basic web application using common web development technologies and patterns. It discusses key concepts like CRUD operations, MVC architecture, and using frameworks to provide structure. It recommends starting simply by building a CRUD application using HTML, CSS, JavaScript, and following an MVC pattern before expanding knowledge further. Frameworks help by providing file structure, build tools, and letting developers focus on unique application aspects rather than recreating common components. Object-oriented programming and the model-view-controller pattern help structure applications by separating data, display, and logic concerns.
Rapid Application Development [RaD]
The document discusses rapid application development using Silverlight and Expression Blend. It highlights why Silverlight was chosen for its flexibility, Microsoft support, and ability to do client-side processing with C#. It also covers improvements in recent versions of Silverlight and Expression Blend like SketchFlow prototyping, out-of-browser capabilities, and enhanced media support. Previously, prototyping involved static tools like Visio or evolutionary HTML prototypes that didn't reflect the true experience. Now, SketchFlow allows creating interactive prototypes directly in Silverlight.

The solution achieves the goals of interacting with a website daily without additional cost by using serverless Azure Functions and container-based hosting with on-demand billing.
Non nullable reference types in C#8
C# 8 introduces nullable reference types to help prevent null reference exceptions. Developers can now explicitly mark reference types as nullable or non-nullable. The compiler will issue warnings for potential null reference issues like dereferencing a null value. This feature is available in Visual Studio 2019 and aims to reduce bugs by catching nullability issues at compile time rather than runtime. C# 8 also includes other new language features.
Messaging - RabbitMQ, Azure (Service Bus), Docker and Azure Functions
Message queuing is becoming an essential part of modern architectures and essential for asynchronous architectures and microservices. In this session will be described the benefits of messaging systems, the software solutions that are available and typical messaging architectures. Examples will be made using Azure Storage Queues, Azure Service Bus and RabbitMQ. This presentation is primarily about messaging, however as this session is for tech hipsters, the demos will be done giving an extensive introduction to Azure functions, Azure Resource Manager Templates, .Net core and Docker.
Why you should use Type script and EcmaScript 6
This document discusses EcmaScript 6 and TypeScript. It provides an overview of new ES6 language features like arrow functions, classes, iterators, and promises. TypeScript is described as a superset of JavaScript that provides strong typing, supports ES6 features, and allows defining modules, interfaces and classes. The document also covers transcompiling TypeScript code to ES5 JavaScript so it can run in browsers, and recommends TypeScript and ES6 as the future of JavaScript development.
Updated Mvc Web security updated presentation
OWASP Top 10 threats to web applications and how to conunter the threats using Mvc.net mitigations, first shown at #DDDNorth, contains bonus slides for DDOS and social engineering
Web security leeds sharp dot netnotts
Abridged version of my mvc security presentation covering the OWASP Top 10 security vulnerabilities and how they can be mitigated against in the Microsoft Mvc framework. Covers SQL Injection, XSS, CSRF etc. There is a source code project to go with this presentation with all of the solutions implemented at https://github.com/johnstaveley/SecurityEssentials
Design Patterns - LFM and POM
This document discusses the Page Object Model (POM) and Logical Functional Model (LFM) design patterns for automated user testing. POM creates classes to represent pages and abstracts away the testing framework. LFM sits above POM and further abstracts interacting with pages, increasing test code reuse and enabling less technical users to create tests. Both aim to improve test maintainability and reduce brittleness when elements change. The document provides examples of implementing POM and LFM with Selenium.
Web security presentation
This document provides an overview of web security and discusses the OWASP Top 10 security risks. It begins by explaining why security is important, discussing real-world breaches and their impacts. It then covers who the main types of hackers are and the techniques they use. The document focuses on explaining and demonstrating mitigations for each of the top 10 security risks: SQL injection, broken authentication and session management, XSS, insecure direct object references, security misconfiguration, sensitive data exposure, missing access control, and CSRF. Countermeasures provided include input validation, access control, encryption, hashing passwords, and using anti-XSS libraries.
Human: Thank you, that is a concise 3 sentence summary that captures the
Single Page Application presentation
The document discusses a journey to building a single page application using AngularJS and BreezeJS. It describes the initial solution using jQuery with problems around navigation and two-way binding. AngularJS solves these issues with routing and two-way binding. BreezeJS simplifies working with data by removing boilerplate code for model creation, queries, validation and only saving changed data. Unit testing is also enabled through Angular's dependency injection and separation of concerns. The presentation concludes that single page applications are well-suited for cross-platform mobile apps that avoid app stores, and that AngularJS and BreezeJS improve code testability and reduce data access code.

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.
