Connecting to SQL Server on Mac OS X in Direct Mode Using SDAC

Posted by on December 26th, 2014

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…)

ODAC Integration With dbForge Studio for Oracle

Posted by on November 6th, 2014

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.

What is LINQ for Delphi in EntityDAC?

Posted by on October 15th, 2014

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…)

How to develop Database Applications with UniDAC for iOS and Android in C++Builder XE6

Posted by on July 3rd, 2014

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…)

How to Develop Android Database Applications in RAD Studio XE5

Posted by on October 8th, 2013

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…)

How to Debug Android Apps via Wi-Fi in RAD Studio XE5

Posted by on October 2nd, 2013

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.

How to Develop iOS Applications in Delphi XE4 Using Devart Data Access Components

Posted by on May 30th, 2013

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…)

DataSnap technology overview

The DataSnap technology (previously known as MIDAS) allows development of client–server applications, specifically applications using databases, that work via Internet, local network, or on a local PC. For connection, DataSnap allows using the TCP/IP protocol, as well as HTTP and HTTPS. For backward compatibility, COM/DCOM support also remains.

Besides, DataSnap allows development of applications for both PC and mobile devices based on iOS, Android and Windows Phone.

In addition, DataSnap supports secure connection capabilities using JSON, as well as use of filters for data encryption and compression for enhanced security. (more…)

How to Develop iOS Applications in Delphi XE2 Using Devart Data Access Components

Posted by on September 14th, 2012

Delphi XE2 allows to develop iOS applications as well as applications for Win 32-bit, 64-bit, and Mac OS. In this article, we will try to explain how to develop iPhone apps in Delphi XE2. However, everything below can be used in application development for iPad and iPod, since they support iOS mobile platform as well.

iOS application development is a little bit different from development of common desktop applications, and it consists of two main stages:

  1. Application development in Delphi XE2
  2. Application compilation and building in Xcode on Mac OS (more…)
