Since RAD Studio XE7 Update 1 was released, the ETTracker.dll library was added to installation. Its purpose is obscure, but its presence in the installation caused serious problems for Windows XP users when installing RAD Studio XE7 Update 1. (more…)
Using SDAC in Direct Mode for access to SQL Server from iOS and Android platforms doesn’t significantly differ from the one on Mac OS X or Windows platforms. Let’s see how this works in a sample below for RAD Studio XE7. (more…)
Devart Company released SDAC and UniDAC for RAD Studio with a new functionality – Direct Mode for connection to SQL Server. The existing providers for SQL Server by Microsoft use the OLE DB interface, that allows using client applications only on Windows platforms. Due to absence of native solutions by Microsoft for Mac OS X, SDAC Direct Mode was the only opportunity to support SQL Server for Mac OS X.
Devart provides a ready solution for work with SQL Server from Mac OS X – Direct Mode. Let’s consider a simple sample of using Direct Mode. (more…)
Database application development is usually divided into two stages: database design and application writing. Oracle Data Access Components for Delphi (ODAC) allow implementation of work with Oracle server, and dbForge Studio for Oracle – database design and administration. Now, for convenient development, integration with dbForge Studio for Oracle is implemented in ODAC.
To enable integration to dbForge Studio for Oracle, in the Delphi main menu select ODAC → Database Tools → dbForge Studio for Oracle Integration.
The main idea of EntityDAC, as well as any ORM for RAD Studio, is to free the programmer from having to implement a business-logic, and the logic of database interaction separately in the application source code. When writing code, programmer abstracts himself from specifics of a DBMS and operates the database entities using structures of his “native” programming language. (more…)

Thank you for staying with us!
In RAD Studio XE6 there appeared an opportunity to develop applications for iOS and Android on C++. Let’s consider the peculiarities of database application development on C++ using UniDAC.
UniDAC is Universal Data Access Components that allow to connect to SQLite, Oracle, MySQL, PostgreSQL, and InterBase (since version XE3) from iOS and Android (you can use UniDAC for connection from Windows to almost all the known databases, but this is beyond the scope of this blog). (more…)
Not so long ago, in RAD Studio XE5 there was introduced support for Android application development. On the Internet there can be found a lot of information about Android application development in Delphi XE5, but when it comes to development of database applications, it becomes much more difficult. The point is that the components and drivers included in the RAD Studio XE5 distribution (for example, FireDAC and dbExpress drivers) have severe limitations: on Android and iOS platforms, they support just 2 databases — SQLite and InterBase. And what to do when you develop a serious business-application, that requires remote connection to Oracle, MySQL or PostgreSQL from Android? We have come across such questions on various forums dedicated to database application development for Android and decided to reveal the topic as detailed as possible. (more…)
The top news of the Embarcadero company in 2013, as well as the direct reason for RAD Studio XE5 release, was certainly support for Android. Android is now of rather great interest for programmers, therefore its support in the Embarcadero’s product in a certain way increased activity in the Delphi community.
With the release of ХЕ5, in a variety of specialized blogs, there appeared publications concerning development of “my first application” for the new platform, in which it is described in details how to create, run, and debug a project. Due to the specifics of the products produced by our company, while preparing for the recent release, we were most interested in the debug process, some peculiarities of which we want to discuss here. (more…)
Half a year ago we published an article describing the process of iOS application development in Delphi XE2. We received quite a lot of positive feedback on that article, but the main thing is that the article helped many our users create their first applications for iPhone, iPad and iPod. Since then, been a long time – and the new RAD Studio XE4 first saw the light of day, in which the process of iOS application development greatly changed. But, fortunately, all the changes were oriented to make the development simple and easier to understand.
iOS development limitations are not for us!
The matter is that iOS has a quite serious limitation on application deployment to iOS devices: you cannot deploy any libraries (*.dylib) along with your application. If you have developed applications for work with databases earlier, you should know that to work with any databases, you need either a client to be installed or a library allowing connection to a certain database. This can be a very serious brick wall when attempting to create a business-application that must work with databases on iOS. (more…)
