Lazarus (software)

Lazarus is a free, cross-platform, integrated development environment (IDE) for rapid application development (RAD) using the Free Pascal compiler. Its goal is to provide an easy-to-use development environment for programmers developing with the Object Pascal language, which is as close as possible to Delphi. Software developers use Lazarus to create native-code console and graphical user interface (GUI) applications for the desktop, and also for mobile devices, web applications, web services, visual components and function libraries for a number of different platforms, including Mac, Linux and Windows. A project created by using Lazarus on one platform can be compiled on any other one which Free Pascal compiler supports. For desktop applications a single source can target macOS, Linux, and Windows, with little or no modification. An example is the Lazarus IDE itself, created from a single code base and available on all major platforms including the Raspberry Pi. Lazarus provides a WYSIWYG development environment for the creation of rich user interfaces, application logic, and other supporting code artifacts, similar to Borland Delphi. Along with project management features, the Lazarus IDE also provides: A visual windows layout designer GUI widgets or visual components such as edit boxes, buttons, dialogs, menus, etc. Non-visual components for common behaviors such as persistence of application settings Data-connectivity components for MySQL, PostgreSQL, FireBird, Oracle, SQLite, Sybase, and others Data-aware widget set that allows the developer to see data in visual components in the designer to assist with development Interactive debugger Code completion Code templates Syntax highlighting Context-sensitive help Text resource manager for internationalization Automatic code formatting Extensibility via custom components Lazarus uses Free Pascal as its back-end compiler. As Free Pascal supports cross-compiling, Lazarus applications can be cross-compiled from Windows, Linux, or macOS to any of the supported Free Pascal compilation targets.

Microsoft SQL Server
Microsoft SQL Server is a proprietary relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including the Internet). Microsoft markets at least a dozen different editions of Microsoft SQL Server, aimed at different audiences and for workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users.
Mobile app development
Mobile app development is the act or process by which a mobile app is developed for one or more mobile devices, which can include personal digital assistants (PDA), enterprise digital assistants (EDA), or mobile phones. Such software applications are specifically designed to run on mobile devices, taking numerous hardware constraints into consideration. Common constraints include CPU architecture and speeds, available memory (RAM), limited data storage capacities, and considerable variation in displays (technology, size, dimensions, resolution) and input methods (buttons, keyboard, touch screens with/without styluses).
Delphi (software)
Delphi is a general-purpose programming language and a software product that uses the Delphi dialect of the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies. Delphi's compilers generate native code for Microsoft Windows, macOS, iOS, Android and Linux (x64).
