Delphi refers to a high level programming language which involves the object oriented and structured programming concepts. Delphi can run on the Window, Macintosh and Unix OS and used to develop the applications ranging from database to mobile applications. Some features of Delphi programming languages are as follows:
- Supports RAD Studio framework
- Includes 250+ Visual Component Library controls
- Provide drag and drop design
- Debugging supports the multi threaded applications
- Supports UML code audits and metrics
- Based on Object Pascal
- Easy to use, easy to compile, easy to read code.
- Include parallel computing library, VCL, development tools, IDE enhancements
Delphi development environment is based on the extension of Pascal language which is termed as Object Pascal. Due to this feature, Delphi involves some advantages like fast compiler, code readability and many more.
Delphi XE is the latest version of Delphi programming language that enables user to build the data rich application fast. It helps user to create the higher quality apps with the benefits of cloud and multi-tier. Some more versions of Delphi programming language are given below:
- Delphi 64-bit compiler
- Delphi Android ARM compiler
- Delphi and C++Builder XE2
On the other hand, some of the major components of Delphi programming language are Resource Reflectors, Annotating Compilers, Symbolic Prediction, Instrumented Libraries, Dynamic Instrumentation, Symbolic Models, Analysis & Visualization and Parameters which enables users to create GUI easily.
Programs of Delphi are mainly split up into source code modules, termed as units. These units are also linked into the program. Uses clause deliver the compiler to the modules with its complete dependencies information. Due to this reason, some Delphi programs do not need header files, preprocessor or make files. Delphi source code is finds by compiler in files by three ways which are as follows:
- Unit source files: In an application, these files involve the most of the codes. Unit source files are terminated with the .pas extension.
- Package source files: these files are used to build the dynamic linkable libraries and these libraries are termed as packages. Package source files terminate with the .dpk extensions.
- Project files: these files are produced when a user used IDE application to build the application. Project files terminate with the use of .dpr extensions.
Delphi 10 Seattle is the most used version of the Delphi programming language. Delphi 10 Seattle is well known for its fastest speed to build the hyper connected applications for various platforms. It allows developers to develop the faster application across mobile, cloud and database platforms.
IDE for Delphi allow users to work with the VCL and CLX libraries. CXL libraries lets user to recompile their code to run under Linux while VCL allow users to develop the user interface for several platforms.
Most of the programmers use Embarcadero software development tools to compile and write their code in IDE. This tool handles the details of source files. In IDE, an application can be built by using VCL components. Some of the major topics that involved in Delphi are as follows:
- Debugging Applications
- Databases with Delphi
- Reporting in Delphi
- Graphing / Charts
- Visual Controls
- Core Library Classes
- Libraries and Packages
Developers can access databases by using Delphi with ADO in which ADO is known as ActiveX data Objects designed for the database application programmers. MDAC includes ADO in itself and acts as an umbrella for Microsoft database technologies. Delhi can be integrated with the entire host of database technologies such as InterBase and BDE. It depends on the developers that which database they want to use and for what. User can access the database content in Delphi by using Connection String which is available in the ADO datasets. This string tells about the location of database to the user.
Furthermore, Database applications can work directly with the desktop applications like ODBC data sources, dBASE and Local InterBase server. On a single machine, Delphi client applications can be scaled between local database and critical network based database. Client/server Edition of Delphi works with the remote database servers such as InterBase, Infromix, Sybase, Oracle and many more.
Rave report is another major concept that involved in the Delphi 7. It refers to a visual report design environment which enables user to make the reporting process efficient and simpler. It can handle a vast range of report formats and involves advanced technologies such as mirroring. Rave designer involves various sections: Event Editor, Toolbar Palette, Status bar, Page Designer and Toolbars. Main features of Rave Report are as:
- Reuse tools
- End user report design capability
- Report management for large applications

Delphi is a high-level, compiled and strongly typed language which supports structured and object-oriented design. Based on the Object, its benefits include easy-to-read code, easy compilation & the use of multiple unit files for the modular programming. Delphi has special features that support Borland's component framework & RAD (Rapid Application Development) environment. Delphi programs are usually divided into source code modules called as units. Most programs begin with a program heading that specifies a name for the program. The program heading is followed by an optional uses clause, then a block of declarations & statements. The uses clause lists units which are linked into the program, these units can be shared by different programs and often have uses clauses of their own. The uses clause provides compiler with the information about dependencies among the modules. Because this information is stored in the modules, most Delphi language programs do not require make files, header files/preprocessor directives.
Features of Delphi:
Delphi is an event driven language.
It supports Object Oriented Programming.
Delphi is an excellent language for creating applications that can connect to virtually any database.
Applications run on operating systems using windows such as Linux, MS Windows and Macintosh platform.
Applications for the Web may be developed in Delphi.
One of the most valuable and important assets of Delphi is the ease of use from the programmer’s point of view. The programming code consists of ordinary English words that are closely related to the style of an algorithm. Once the design of an algorithm solves a problem, it is easy to convert the solution into the Delphi
