A Multi-Tier architecture separates the UI/Presentation, the application and business logic layer, the data access layers, and the database itself in separate applications, potentially running on different computers. In this blog post we’ll examine some of the key traits of this architecture and discuss key reasons for adopting this model.
Multi-tier architectures are fairly common these days and they are becoming even more relevant in today’s mobile world, given the traditional client/server m...
The RAD Server Field Service Template provides an end to end field service application template for routing appointments, managing parts, and user administration. It is made up of a REST server module, a desktop client, and a cross platform mobile client. The template can give you a head start in building your own field service solutions. This blog post is about the offline capable mobile client app that comes with the template. You can download the Field Service Template for free from Embarcade...
If you want to display only a range of results from a recordset you can using paging (otherwise known as pagination) to do so. It is a common pattern when doing web development to give the user 20 results for example and then the ability to move to the next page. If you are implementing a REST API in RAD Server you might also implement this functionality instead of delivering 2 million rows for the query you only deliver the first 20 rows and the next 20 can be requested in the next call. Obviou...
To prepare for the appearance of C++17 support in the "Carnival" release of C++Builder (RAD Studio August 2018 Roadmap), here are some recent articles that have appeared in the C++ community. To stay up to date on what's happening with ISO C++ you should bookmark the ISO C++ foundation's website.

The FireDAC Enterprise Connectors (#FDEC) by CData and Embarcadero make it really easy to work with various APIs just like you would any SQL database. For example if you want to publish the results of a query to a Google Sheet (which I find incredibly useful) then it is just a few FireDAC components and you are off to the races. You might run into an API limit though.
What is an API limit? Most rest services have a limit to how often a client can call a specific API within a certain amount of t...
Choosing a programming language to learn and utilize is an extremely personal choice and not one that developers take lightly. C++ has a long history as a popular language used to create Operating Systems, drivers, gaming engines and so much more. It expanded the C language by adding classes, inheritance and abstraction to its core, making it my favorite language to use.
C++ is the first language that I learned in school and my experience with it actually started with Borland’s, now Embarcader...
Delphi CE Bootcamp is an 8 week FREE instructional lecture covering many different areas of Delphi development and focused on new developers as well as existing ones. The series begins next week, and I'm the first instructor. Lectures will be posted each week on each weeks topic and lecture replays will be available if you're not able to attend during a week. We expect to have also some Q&A sessions.
The bootcamp is free but be sure to reserve your space early to make you get in, at:

A common pattern when inserting data into a database table which has an auto increment field set on it is to use an SQL query to select the last inserted ID of the newly created record. Once you use your TFDQuery to run your INSERT query you can run this second query to get the newly inserted auto increment ID. Different databases have different SQL queries to accomplish this. MySQL for example has a SELECT query function that you can run called LAST_INSERT_ID() (example: SELECT LAST_INSERT...
Last week, we released the FMX Stencils pack. The FireMonkey Stencils pack was designed to enhance communication between designers and developers who are building multi-device applications using the FireMonkey framework in Delphi, C++Builder and RAD Studio.
One of the challenges for designers in an application development cycle is understanding the breadth of UI components and styles available in the FireMonkey framework. We addressed this by providing visual assets that match the UI co...
C++ has a long history, beginning in 1979, with Cpre, which added classes to C. By 1980, it was C with Classes. And then in December of 1983, the term C++ was first used, suggested by Rick Mascitti. That's thirty-five years ago this year! Read more in this fascinating article by Bjarne Stroustrup, which also discusses many other aspects of C++’s history. We also recently posted a short history of C++’s various standards ourselves.
My own journey with C++ began much later than ...
