• JDBC in C++: a commercial product which provides the functionality to use JDBC in C++. Have a look(none open-source).
• Loki C++ Library: Loki is a C++ library which demonstrates and encourages the use of generic programming and designe patterns. It was written to accompany the book entitled 'Modern C Design.' The library includes a parametrized smart pointer class, generalized functors, a multithreading abstraction, and some help for important patterns.
• OpenTop: Cross-Platform C++: OpenTop is a radically new C class library that provides the means to create powerful and robust network-oriented applications and greatly simplifies their development.

  At its core, OpenTop contains framework classes that provide vital facilities that are absent from the C standard library. These include:

  • Networking
  • Unicode
  • Multi-threading
  • Memory and resource management
• The Boost C Libraries: C++ libraries for boost your performances.
• Log for C++: Log4cpp is library of C classes for flexible logging to files, syslog, IDSA and other destinations. It is modeled after the Log4j Java library, staying as close to their API as is reasonable.
• ACE Overview: The ADAPTIVE Communication Environment (ACE) is a freely available, open-source object-oriented (OO) framework that implements many core patterns for concurrent communication software. ACE provides a rich set of reusable C wrapper facades and framework components that perform common communication software tasks across a range of OS platforms. The communication software tasks provided by ACE include event demultiplexing and event handler dispatching, signal handling, service initialization, interprocess communication, shared memory management, message routing, dynamic (re)configuration of distributed services, concurrent execution and synchronization.
• Crypto Library 5.1 - a Free C Class Library of Cryptographic Schemes: Crypto Library is a free C class library of cryptographic schemes.
• nn-utility: THE AIM OF THE NN-UTILITY project is to create a neural network library that takes care of the tedious programming of networks in object oriented C . The library makes the creation of network topologies and weight definitions very easy. The library also has some default functions, making the programming of sigmoid, kohen, binomial, and radial basis functions simple. On top of this the library is composed of some accessories, like simple bitmap creators and readers, enabling networks to be trained with bitmaps.
• IT++: A C++ library of mathematical, signal processing, speech processing, and communications classes and functions. It has been developed by researchers in these areas. The kernel of the package are templated vector and matrix classes and lots of functions for vectors and matrices. As such the kernel is similar to the Matlab functions.

Asset Oriented Modeling (AOM)

A modeling method that is:

• expressive
• compact
• modular
• simple

AOM is designed with these goals in mind:

• unified approach to entities and relationships (assets)
• support for higher order relationships
• support for complex data structures based on regular grammars
• namespaces and scopes

• YAML Ain't Markup Language: "YAML(tm) (rhymes with 'camel') is a straightforward machine parsable data serialization format designed for human readability and interaction with scripting languages such as Perl and Python. YAML is optimized for data serialization, configuration settings, log files, Internet messaging and filtering."

To understand the spirit of AOP, you must understand the following issues:

• separation of concerns: referring the Law of Demeter, a project's efficiency increases if all the concerns are well modularized and if you only have to speak to your direct friends to make a modification of the program (this is a very old principle and the OOP gives some answers)
• crosscutting: in a complex system, there are always some concerns that are not easily modularized, especially common-interest concerns that, by essence, are used by several modules (i.e. several modules use/share a well-known service of a module --such as a logging or a persistence service)
• dependencies inversion: the best way to avoid crosscutting is to NOT use the well-known services that crosscut. This is possible by reversing the dependencies (i.e. the well-known service shall use the other modules instead of the contrary). This dependency inversion is implemented by aspects...

Projects:

• Aspectj
• JAC
• Nanning Aspects AOP framework
• AspectWerkz is a dynamic, lightweight and high-performant AOP/AOSD framework for Java. AspectWerkz utilizes runtime bytecode modification to weave your classes at runtime. It hooks in and weaves classes loaded by any class loader except the bootstrap class loader. It has a rich join point model. Aspects, advices and introductions are written in plain Java and your target classes can be regular POJOs. You have the possibility to add, remove and re-structure advices as well as swapping the implementation of your introductions at runtime. Your aspects can be defined using either an XML definition file or using Runtime Attributes

• Improve modularity with aspect-oriented programming: Aspect-oriented programming (AOP) is a new programming technique that allows programmers to modularize crosscutting concerns (behavior that cuts across the typical divisions of responsibility, such as logging). AOP introduces aspects, which encapsulate behaviors that affect multiple classes into reusable modules. With the recent release of AspectJ by Xerox PARC, Java developers can now take advantage of the modularization AOP can provide. This article introduces AspectJ and illustrates the design benefits that result from its use.
