Dimensional Data

  Showing a large volume of information at once on a website without affecting the loading speed while allowing users to do complex operations on the data is quite challenging. To solve this problem, web developers can use data grids that render data in rows and columns similar to an HTML table. Today, several JavaScript grid libraries, such as Sencha Ext JS, allow users to load millions of records efficiently and do useful operations such as sorting, scrolling, filtering, and grouping. However, you must know how to get more results out of a JavaScript grid library so that users can get the maximum benefit and the best experience in table operations. If you are a web developer looking forward to using our JavaScript grid library, follow this article to know how you can get the most out of it. Why do you need to use pagination? When there is more information to load, rendering it in one page may require users to unnecessarily scroll through the page, which will affect the user experience. In such cases, you can use pagination, allowing users to view the entire data set by navigating through pages. Most javascript grid libraries come with support for pagination. Ext JS grid library also offers an automatic pagination option through its specialized toolbar that loads part of the data on one page. Therefore, always ensure to use the pagination option to make a web page less complicated and user-friendly. How to integrate Widgets into your grid? Sometimes data in a grid can show important information to the users, such as trends, patterns, progresses, and percentages. It will be really helpful if there is a way to visualize the patterns hidden on those data to better understand the story behind the numbers in grid columns. For such scenarios, some JavaScript Libraries provide the ability to integrate UI widgets for data visualization. For example, Ext Js Grid Library, allows you to add UI components or widgets such as bar charts, buttons, inline graphs, etc., into columns. Why is Pivoting important? If you want to show information summaries to your users, make the best out of pivoting in grid libraries. A pivot grid helps to show summaries from a large amount of information. It also enables users to understand the useful insights from the loaded data set. For example, suppose you are developing a web application for a company that helps management to understand which products have the most sales. In that case, you can easily show that information using pivoting. Why do you need to make use of data export and import? Clients are often required to export records into an external datasheet like an Excel sheet to separate references to the data. Allowing users to export the data in different formats, including CSV, PDF, and text format is a useful functionality you can offer. When exporting data, it is important to understand how much data, a specific format like an excel sheet, can contain to allow data export part by part. Users then can use the data for their analysis and as internal references. In addition, importing data from external sources is very useful. Check if your grid library provides these features and use them whenever you want to build a dynamic grid from an external data source. Why […]

Every organization has different tools to support internal processes. As companies scale, IT teams are faced with the growing complexity of user requirements, which often go beyond the capacity of consumer software. IT executives everywhere are turning their attention to custom solutions to better accommodate their organizations’ needs.  In this article, we’ll dive into the key areas for choosing a development framework for your enterprise applications. You’ll learn about the common challenges with open-source software and what makes Sencha Ext JS the best alternative solution. What to consider when developing enterprise software  Regardless of the usage areas, the foundation of every high-performing enterprise software boils down to the development framework. If you’re in charge of developing a new application, chances are you’re considering open-source frameworks like React or Angular.  Now, open-source packages come with a whole different set of challenges: Security risks: Enterprise applications process sensitive data, so you’d want control over the system accessibility and user permissions. If you rely on open-source projects developed by a broader community, there may be little control over the source contributions.  Maintenance effort: Enterprise software has unique requirements. Unfortunately, many open-source frameworks are not enterprise-ready for your particular use due to the nature of third-party code. You’ll also need to compromise the standard support your IT team requires. Ease-of-use for user adoption: Lack of UX expertise or bandwidth makes it difficult to deliver the optimum user experience unless your team has reusable UI components for every project. Considering the factors mentioned above, you should handle open-source frameworks with care, especially for mission-critical environments.  An ideal development framework should also offer: Version control or IDE-like experience with a native debugger Robust and granular access control functionalities Option for being self-hosted  Why choose a proprietary framework? The easier you can build and deploy apps, the more efficiently you’ll be able to address constant feature requirements from your users. And that’s just one among several advantages of closed-source frameworks. Enterprise-grade security  Security is probably the main driver for closed-source adoption among enterprises. Having controlled and authorized access to the source code is critical for enterprise software. Dedicated support and training resources You don’t have to worry about spending hours searching through docs or community forums to find answers to your problems. Using a commercial framework, you’ll get professional support from the vendor. The available documentation and user guides also directly cater to your use cases. High code quality Open-source frameworks don’t necessarily have the same level of attention to quality as their commercial counterparts. Proprietary options give you complete customizability to design software for very specific needs so your team can save time on development while ensuring the usability of the code immediately upon installation. On top of these benefits, you’ll be provided with a standard license agreement, which comes with indemnification and warranty. This means fewer headaches over open-source licensing terms and compliance issues. Ext JS: A powerful JavaScript framework for custom software development Ext JS is a JavaScript framework that offers a component library for building rich client, cross-platform web applications. It is especially suited to handle enterprise applications with large volumes of data. With Ext JS, you’ll have access to over 140 prebuilt UI components, including form builder, calendar, tables, charts, and more. Plus you’ll have the ability to visualize and analyze data […]

Every veteran web developer once started from a place of rudimentary skills. You get more proficient at web development only when you devote time and effort to the craft and learn new technologies. The advent of the internet has brought plenty of resources at your disposal for you to utilize for a smoother learning experience. Therefore, you shouldn’t shy away from trying out things one at a time and growing further. While the learning process looks different for every beginner developer, one common aspect is their mistakes. Such mistakes are great teachers that give a lifelong lesson for better professional growth. However, it would be more beneficial if beginner developers could learn from each other’s mistakes and save themselves from wasting time on repeating them. When it comes to a JS grid, the scenario is very similar. There are many libraries and tools for you to explore and learn. However, you can benefit from a resource that provides you with a roadmap about data grid libraries and how you can start using them. You could learn about some viral libraries like Sencha Ext JS that some major enterprises use for building robust data grids. This article will focus on what aspects make data grid libraries stand out and what you should know as a beginner trying out data grids. What Tool Can Help Build A Robust JS Grid? Building a JS data grid means working with two different technologies that are neatly integrated into each other. One is JavaScript, one of the fundamental languages of the web that controls the functionalities and back-end logic of websites. The other is data technologies that handle, process, and chart up the data into a grid for you and others to use.  Since both of these are radically different, you need a tool that integrates both of them sufficiently. The best way is to utilize a JS grid library within your codebase and use its methods for building data grids. While you could look into other options, such as using the front-end framework or using HTML to build grids, using a dedicated grid library has much more advantages. However, you’ll need to ensure some vital fundamental aspects in your chosen JS grid library since there are so many options out there. Some of them are briefly described below: Robust Data Features: The JS grid library should have all the essential data operations you and others can use. Standard operations like pivoting, filtering, managing rows and columns, and aggregation are a must. Strong Visual Aesthetic: It won’t be helpful if all power of the grid library is behind the screen and the rendered grid is unusable. Therefore, it must have a user-friendly UI for a better user experience. Thorough Documentation: Every developer needs help occasionally, and the tools they use should provide that. The JS grid library should supply documentation and examples for a better development experience.  Easy-to-use Interface: While the grid library should come packed with features and a fantastic UI, it shouldn’t have to translate to a challenging development experience. The library’s methods and interfaces should be a breeze for developers to work and create powerful data grids with. You can trust it with your data grids after you have ensured that your preferred data grid library will deliver in all the above […]

The pressure a modern web developer faces daily requires them to develop effective decision-making skills and always be on their toes.

Nowadays, a large amount of data keep generating in businesses, and sometimes they need to display that information on websites for the consumers. The common way of displaying data on a website is using an HTML table. However, showing a large amount of data in an HTML table is cumbersome, especially if it slows down the entire page load. Therefore, if you want to show a large amount of data in a table on your web page, using a grid is the best way to do that.  A grid is similar to a table in HTML elements, but it allows you to easily fetch, scroll, sort, group, and filter a large number of data rows. When loading and processing large data sets, the performance is important because it should not hinder the user experience.  A high-performing js grid has a good initial page load time which is the amount of time the grid takes to load the initial data set. It is also efficient in dynamic filtering or the time it takes to filter one column. In addition, when considering a large amount of data in a grid, users often need to scroll through various sections of the grid to see the rest of the data. This scrolling speed is a good indicator of grid performance, and high-performing grids have a good scrolling speed that amounts to seconds.  Ext JS data grid is a high-performing grid that allows loading and manipulating a massive data set within milliseconds. In most benchmarking experiments, almost all the JS grid types from different vendors have shown good initial page load time and dynamic filtering speed. However, all those grids have shown a greater variation in scrolling speed, except when viewing the first few records of the grid. the Ext JS data grid has an outstanding scrolling speed which is 300x faster than other leading data grids, which can fetch and display massive sets of data in less than one second Ext JS grid consists of two parts which are Ext. data.Store and Ext.grid.The panel. The datastore represents the data and the set of columns in the grid to render.  The data stores give Ext Js grids the capability to load data inline and load them dynamically on-demand. It also allows loading nested data, sorting, and filtering. The following example shows a simple data store specified in JSON data structure which will be loaded to Ext Js Grid. Ext.create(‘Ext.data.Store’, { storeId: “myProductStore”, fields: [‘productid’, ‘title’], data: [{ ‘productid’: ‘1’, “title”: “LindtChocalate” }, { ‘productid’: ‘2’, “title”: “Milk” },] }); Ext.grid.The panel is the key component that allows displaying a massive amount of tabular data on the client side. For example, the below code generates a simple grid with two columns. The grid will load the data we specified in the above-specified data store. The grid generated will consist of the columns specified below and the header title ‘Products .’ Under the title will show the data directly below the header title.  var columns = [{ text: ‘productid’, dataIndex: ‘productid’, flex: 1 }, { text: ‘title’, dataIndex: ‘title’, flex: 1 }]; var grid = Ext.create(‘Ext.grid.Grid’, { title: ‘Products’, store: “myProductStore”, columns: columns, layout: ‘fit’, renderTo: document.body, width: ‘100%’, height: 300 }); Raw and Column operations, rendering, and scrolling Ext JS grid consists of a rich set […]
