Dimensional Data

This post shows how to create a RAD Server REST Endpoint (JSON Web Service ) using the RAD Server Database Endpoints Wizard using a FireDAC Connection, to create REST Endpoints for CRUD functionality. And create a Sencha Web Client Application with a CRUD Grid for our data! RAD Server Steps1. Using RAD Studio, Delphi or C++ Builder:File | New | Other | RAD Server | RAD Server Package | Click OK. 2. On the RAD Server Package Wizard, select Create package with resource: Click Next.3. Enter a Resource Name (any name). I’m using the name MyDataSelect DataModule for the File type. Click Next. 4. On the RAD Server Package Wizard, un-select Sample Endpoints, and un-select API Documentation.Select Database Endpoints Click Next. 5. Select an existing FireDAC connection, and Login to your database. Click OK. 6. Select one or more tables to use for your Sencha CRUD Grid Web application. Here I’m selecting Country, Customer and Employee Tables from my Employee Database: Click Finish. 7. Your RAD Studio, Delphi or C++ Builder creates your DataModule, with your FireDAC Connection (FDConnection), and FireDAC Query components (qryCountry, qryCustomer, qryEmployee) for your Country, Customer and Employee Tables, and RAD Server (EMS) DataSetResource Components: The new EMSDataSetResource component allows for greater control of the data retrieved by desktop, multi-device, web and other service-based applications that connect to your RAD Server application. Using this new component RAD Server applications can provide access all of a data set’s data, a specific page of data, updating a data set record, creating a new data set record, and deleting a data set entry. 8. The Database Endpoints wizard we used in step 4, also added TEMSDataSetResource components for each of the tables. Looking in the Object Inspector, we see the Allowed Actions property for these tables: List, Get, Post, Put and Delete, to give us full CRUD functionality! 9. Save (File | Save Project As) your RAD Server Module in a new folder, with the name: RadServer_Sencha_CRUD: 10. Build and Run your RAD Server Module. Your RAD Server Log shows you your REST Endpoints to access data from your Tables. For example: GET for the Employee table has this REST endpoint: {“name”:”dsrEMPLOYEE.List”,”method”:”Get”,”path”:”mydata/EMPLOYEE/”The RESTEndpoint would be: http://localhost:8080/mydata/EMPLOYEE/ 11. To test this Rest Endpoint, click the Open Browser button on the RAD Server UI. and Enter the REST Endpoint: http://localhost:8080/mydata/EMPLOYEE/This is your JSON Web Service for your Employee table data.You should see a JSON Array returned for your Employee Data: Great! The RAD Server part is complete.Next, lets create a Sencha Web Client Application with a CRUD Grid for our data! Sencha Web Client Application Steps 1. Using Sencha Architect; 2. New Project | Blank | Classic Project Click Create. 3. This creates a new Sencha Ext JS Classic Web Application: 4. Click the Sencha Data UI Builder icon:  5. For the Data Source, select JSON Web Service: 6. For the Model Name, let’s call it myModel. For the URL of this service, enter: http://localhost:8080/mydata/EMPLOYEE/ 7. Parts to Create.  Select all parts (Model, Store, List View, Details View, Form View, and Controller. Click Import Fields: 8. All the columns (fields) from your Employee table get added: 9. Click Generate 10. The Sencha Project Inspector shows your project has been created with your Views, and Model: 11. Select your MyModels View. Your […]

The world is becoming increasingly data driven. Our everyday reality now is a hugely interconnected world society with data points on everything from what we want to purchase to how many times we braked too hard on our last road-trip. Without data, businesses cannot succeed and expand. They may have a stream of data coming from different sources, but it is useless without analytics. But did you know the next big thing in data analytics and reporting is your IDE software? Why should we care about data? Data is a critical asset for businesses as it helps them make informed business decisions. Plus, data usage drives the success of a business. Which depends on analytics, and the usage of reporting tools. Reporting tools make all the information easier to parse. Without analytics and reporting tools, informed business decisions are hard to imagine. This is where Yellowfin comes into play. Gartner surveyed CIOs for analytics and reporting tools. They asked for their best pick in business’s success. As a response, the highest 24% voted for data analytics. CIOs also believe that data analysis is important to act on data. Which returns invaluable insights.  So, if an enterprise wants to succeed, it must keep up with the latest trends in data analytics. Don’t know where to look? No worries! We have prepared this guide solely for this purpose.  Continue reading to learn about big things in data analytics and reporting tools.  What are the big things in analytics and reporting tools? What are contextual analytics? Contextual analytics is a chart embedded on the page with the data. It also includes picturing and the related actions for better insights. It embeds dashboards and analytics solutions into a software application’s core workflows. In addition, users get the benefits of analytics directly in the framework. Before contextual analytics, the users had to switch away from their working environments. They did so to investigate data or derive insight. But now, with contextual analytics, the data is delivered to the end-user directly. It is in the user interface and the transaction flow. With one click, users can get instant, guided, and dynamic insights. Which helps them to train and make decisions while working as usual.  The contextual analytic’s goal is to maximize the business benefits. It does so by supporting or triggering actions users take within the app.  What are augmented analytics? Augmented analytics uses enabling technologies like AI and machine learning. It helps with data preparation, insight explanation, and insight generation.  Its primary purpose is to boost how users explore and analyze data in analytics and BI platforms. It augments the expert and citizen data scientists. It speeds up machine learning, data science, and AI model development. So, augmented analytics is transforming how businesses prepare data. It helps find insights and share the findings from those insights. It will be no surprise if data analytics becomes mainstream. It is one of the next big things in analytics and reporting tools. Thus, data and analytics leaders should not wait and incorporate it now.  What are automated analytics? Automated analytics detect relevant anomalies, trends, and patterns. Once found, it delivers insights to users in real-time with no manual analysis.  Enabling technologies like machine learning and AI are used to monitor working performance. They also help search large datasets […]

Are you considering developing a mobile application? Your thoughts immediately turn to native app development. Still, before you decide, it is critical to understand that native apps are designed for something like a specific platform, such as iOS or Android, with a different codebase. Cross-platform apps, on the other hand, can target multiple platforms with a single codebase. Here in this brief article, you will learn about how to save money on cross-platform development frameworks. Because of the numerous advantages of having apps which can work on multiple devices – both desktop and mobile, developers worldwide embrace cross-platform app development. Today, there’s a great choice of frameworks to allow developers to create apps for multiple platforms using shared code to reduce the amount of additional work needed to address the differences the devices may have. In this article we explore what we mean by the term cross platform development and how we go about creating apps that can work for our users no matter what their choice of target whether it be desktop or mobile. What is cross-platform development? Software that can run on multiple devices and operating systems can be an example of a cross-platform application. Moreover, as a developer, you can define cross-platform apps by building a cross-platform app out of the same source code without changing so much on the core.  For instance, Delphi provides a cross-platform development ecosystem with its set of tools and libraries. The FireMonkey framework is the core tool for creating cross-platform and native applications using the same code. by Adding FMXLinux you can deploy to Linux powered platforms and also create Web Apps FireMonkey framework is one of the leading visual frameworks for creating cross-platform apps. Its architecture lets you create high-performance and secure applications.  Screenshot of a Game built with Delphi – RAD Studio Do you really need to use a cross-platform development framework? Not all cross-platform development tools provide you with the best experience when creating it or a great user experience for the users. Because cross-platform applications utilize layers of abstraction to make the thing work and sometimes you might not get the true native app feeling. For instance, apps built with hybrid technology or web technologies do not provide security over your product. Furthermore, there may be a problem when accessing hardware functionalities.  Nevertheless, Delphi, with its promising FireMonkey framework, is the solution for all. With FireMonkey visual framework and Delphi IDE, you can design GUI apps in no time and build/deploy them to Windows, macOS, Android, iOS and Linux devices quickly. Moreover, you can access any device or the operating system feature with built-in helper functions. Microsoft also has a new technology called MAUI, which is similar to FireMonkey’s architecture. However, it is still in preview, and as you can see, FireMonkey has been in active development for more than a decade and is the most stable cross-platform visual framework. Create Multi-Device Native Application using a Single Code Base Are cross-platform frameworks the future of app development? This is no secret that most companies, primarily startups, choose cross-platform development frameworks to target several markets easily. That’s why we may say that these cross-platform frameworks are in demand, and over the years, it has shown that cross-platform app development can help reduce cost and engineering time dramatically. We can […]

Did you know it’s easy to make use of some truly excellent Python libraries to super-charge your Delphi app development on Windows? Adding Python to your toolbox of Delphi code can enhance your app development, bringing in new capabilities which help you provide innovative and powerful solutions to your app’s users, which combine the best of Python with the supreme low-code and unparalleled power of native Windows development you get with Delphi. Are you looking for how to build a GUI for a powerful AI library? You can build a state-of-the-art deep learning solution with fastai on Delphi. This post will show you how to build a Delphi GUI app, dedicated to the fastai library. Watch this video by Jim McKeeth, as a comprehensive introduction about why you can love both Delphi and Python at the same time:   What is the fastai library? fastai is a deep learning library that provides practitioners with high-level components that can quickly and easily provide state-of-the-art results in standard deep learning domains and provides researchers with low-level components that can be mixed and matched to build new approaches. It aims to do both things without substantial compromises in ease of use, flexibility, or performance. fastai includes: A new type dispatch system for Python along with a semantic type hierarchy for tensors A GPU-optimized computer vision library that can be extended in pure Python An optimizer which refactors out the common functionality of modern optimizers into two basic pieces, allowing optimization algorithms to be implemented in 4–5 lines of code A novel 2-way callback system that can access any part of the data, model, or optimizer and change it at any point during training A new data block API And much more… And the best of it is, fastai is organized around two main design goals: to be approachable and rapidly productive, while also being deeply hackable and configurable. fastai is built on top of a hierarchy of lower-level APIs which provide composable building blocks. This way, a user wanting to rewrite part of the high-level API or add particular behavior to suit their needs does not have to learn how to use the lowest level. Hierarchy of fastai APIs.   How do I install the fastai Library? You can easily install fastai with pip: Or, if you are using Anaconda Python distribution, you can use this command to avoid complexities and conflicts between required libraries: conda install -c fastai -c pytorch -c anaconda -c conda-forge fastai gh anaconda conda install –c fastai –c pytorch –c anaconda –c conda–forge fastai gh anaconda   How do I build a Delphi GUI for the fastai library? The following is the user interface structure for our project: User interface structure for our fastai4D project. Here is the list of Components used in the fastai4D demo app: TPythonEngine TPythonModule TPythonType TPythonVersions TPythonGUIInputOutput TForm TMemo TOpenDialog TSaveDialog TSplitter TImage TPanel TLabel TComboBox TButton Navigate to the UnitFastai4D.pas, and add the following line to the FormCreate, to load our basic fastaiApp.py: Memo1.Lines.LoadFromFile(ExtractFilePath(ParamStr(0)) + ‘fastaiApp.py’); Memo1.Lines.LoadFromFile(ExtractFilePath(ParamStr(0)) + ‘fastaiApp.py’); You can seamlessly load the fastai app python file inside the UnitFastai4D.pas file. And make sure that the fastaiApp.py is in the same directory as our Fastai4D.exe or inside your Delphi project folder. You can change the “fastaiApp.py” with any fastai script you […]

Android Studio is indeed the go-to Android App Builder Software for creating Android applications with Java or Kotlin. Since applications built with Java and Kotlin provide full native app development and all the available features, it really provides long-term success. Moreover, the community around Java and Android Studio is vast, and if there are issues that arise, there is a hundred per cent guarantee you can find the solution easily. But there are some cases where the Android Studio with Java or Kotlin cannot be a solution.  Android is very likely the most popular operating systems for mobile and portable devices with the flexibility to deploy primarily any device that can handle it. It is projected to grow and dominate not in just mobile, tablets, PCs, cars, set-top boxes, smartwatches, home appliances, and more. For these reasons, learning how to create Android applications is a must, but choosing the proper Android development framework and a programming language is tricky with its app development ecosystem. For instance, you can see an Android developer using Android Studio but also looking for other options to develop apps with more productivity. I help you select the right Android app builder and the proper framework for your projects. How to compare Android app builders and Frameworks? It really depends on the company. For instance, start-ups use hybrid app development technologies mainly because they are free and open-source but, in reality, do not provide much productivity and higher security over your code. Numerous Android app development frameworks share many identical characteristics. But with their certain unique features, creating specific types of projects can be more accessible. Moreover, the app builder environment also plays a significant role. For instance, one framework can be used to create e-commerce apps which have easy to integrate solutions for third party services but lacks graphical user interface development. Or it requires you to work with XAML to design UI, which is not productive and not intuitive at all. Here are some criteria you should know to compare framework and Android app builders: Cross-platform capability Popularity and resourcefulness Easy & Fast UI Designing Choosing a cross-platform framework where you can build native but cross-platform applications with one codebase is no news in the current state of technology. But not all framework and development platforms support this power with the ideal architecture. FireMonkey framework, with its RAD Studio app development ecosystem, you can get all the modern features and environment to build any application that can run on major platforms like Android, iOS, Windows, macOS and Linux. Additionally, you can create business-oriented web applications. The best thing about the RAD Studio development environment is that you can prototype and design applications 5x faster than most other app builders. It gives you the low code app development platform and traditional software engineering ecosystem. Why should you select RAD Studio for your Android app development? First of all, I recommend you try out the Delphi Community Edition or RAD Studio trial version to build various types of applications. When you install the IDE with its framework and libraries, you get a set of sample applications. You can see how simple and fast to create different applications with the RAD Studio platform.
