Once you can build reports in Power BI, the next questions are usually about figures that do not exist in the data directly, such as profit per line, year-to-date sales, a comparison with last year or a product ranking. The answer is DAX (Data Analysis…
An online shop of your own lets a business control its storefront, customer data and promotions instead of relying only on marketplace platforms. WordPress with WooCommerce is an open-source combination used by many shops, because you can start without…
Before you can build a dashboard, most data has to be prepared. Excel files have multi-level headers, monthly figures sit in columns, product names are spelt inconsistently and data from several systems has to be brought together. Fixing this by hand every…
Most web teams receive designs as Figma files, but turning a design into a web page that matches it, works well on every screen size and is easy to change takes both the ability to read design files and a sound understanding of modern HTML and CSS. Writing…
Modern web design is not judged on looks alone. Pages must work well on phones, tablets and computers, load quickly and be usable by everyone. Many designers already lay out pages in Photoshop, but when the design is built as a real site, spacing, colours and…
Websites today must look good on every screen size, load quickly and work for everyone. Yet many teams still design pages as static pictures and leave developers to guess, so spacing, colours and type sizes drift from the design, pages break on mobile and…
WordPress has changed the way themes are built. Modern themes are block themes: colours, fonts, spacing and layout for the whole site live in theme.json, pages are assembled from block-based templates and template parts, and site managers can adjust the…
A dashboard brings data from many sources onto one page, so managers and teams can see key figures, trends and the status of their work at a glance. A good dashboard is more than attractive charts: it has to order information so it is easy to read, display…
Many developers build web pages that work perfectly well yet still look cluttered, hard to read or untrustworthy, and they are not sure what to fix. The Refactoring UI approach closes this gap with practical techniques from a developer's point of view, such…
The data in an Oracle database is often the heart of an organisation's systems, yet many sites still have backups that have never been test-restored, do not know whether they can roll data back to before a mistake, and have no clear procedure for when a disk…
Many problems in business systems start with the database structure: duplicated data that is changed in one place but not another, reports that pull figures that do not match, or systems where new features are hard to add because the tables were related…
Websites today must look good on phones, tablets and desktops, and writing fully responsive CSS from scratch takes a long time to learn. Bootstrap 5 is a CSS framework that makes responsive layouts quick with its grid system, utility classes and ready-made…
As an Angular application grows in pages, users and the number of developers on the team, simply making it work is no longer enough. You need a structure that is easy to maintain, clear responsibilities through dependency injection, systematic state…
Once you can write Flutter, the next challenge is building apps that hold up in real organisational use. That means code that is easy to maintain, systematic state management, multiple languages, data stored both on the device and in the cloud, notifications…
Once you can build a basic Flutter app, real projects ask for more than good-looking screens. The app has to talk to a back-end API, create, update and delete data, sign users in securely, look right on phones and tablets, and use device features such as maps…
If you want to build mobile apps that run on both Android and iOS from a single codebase, Flutter remains one of the most popular choices. You write everything in one language, Dart, the apps feel close to native, and Hot Reload shows every change instantly.…
GitOps is a way of doing continuous delivery that treats Git as the single source of truth for a system. Every change to applications and infrastructure happens through commits and pull requests that can be audited later, while a controller inside the cluster…
JavaScript runs on every web page, and it has improved greatly since ES6. Many tasks that once needed jQuery, such as selecting and changing the DOM, handling events and calling APIs, can now be done with standard JavaScript. Even so, many websites, internal…
Modern web applications usually separate the frontend from the backend: the backend exposes a Web API and the frontend is a single page application that calls it. ASP.NET Core on .NET 10 (LTS) is a robust choice for enterprise APIs and runs on Windows, macOS…
MEAN Stack is a set of technologies that uses JavaScript and TypeScript across the whole system: MongoDB for data, Express and Node.js for the API, and Angular for the web front end. Teams can use one language on both frontend and backend, share data models…
Many modern applications need to store data whose structure changes often or is nested several levels deep, such as product data where each type has different attributes, user profiles or logs from different systems. A NoSQL database such as MongoDB stores…
The problem of software that runs on one machine but breaks on another comes from mismatched environments. Docker solves it by packaging an app with everything it needs into a container that runs the same way on a developer's laptop, a test server and…
Once you can write basic Flutter, the next hurdle for many people is building an app with several screens that loads real data from a back end and offers the features users expect, such as loading more items at the end of a list, pull to refresh,…
A good web page needs a sound structure, works well on both phones and computers, and looks appealing. HTML5 and CSS can do more on their own than many people expect, from forms that check their own input and videos with captions to gradients, shadows and…
