Free abstraction layer software for linux

The CAN Abstraction Layer (CANAL) provides a single interface for programs to use different CAN drivers.
It consists of a CANAL daemon that handles client and driver communication, a canalLogger that logs messages in a window, and a simple diagnostic application. C++ clases and DLL/DL interfaces are provided.
Enhancements:
- The configuration readings for CanalWorks were upgraded.
- A GUID ordering problem in canald was fixed.
- A problem with clear message list switch in CanalWorks was fixed.
- A problem in which Linux version Level I received a thread with an invalid count returned for DataAvailable was fixed.

MySQL Abstractor package contains PHP classes that implements a MySQL database abstraction layer.

It provides several classes. There is one for establishing connections and executing SQL queries, another for composing and executing SELECT, INSERT, UPDATE and DELETE queries from a list of parameters, and a wrapper class to simplify the usage of the other two classes.

Wiaflos Accounting project is an attempt to create a multi-platform server-client based accounting system.
The goal is to have a central accounting engine which can either run on a dedicated server or on the same PC as the client interface. The accounting engine will provide a full SOAP API for easy writing of GUI/Web interfaces or tieing into inhouse systems. Seeing as the accounting engine is written in Perl and makes use of a database abstraction layer, the engine should run on nearly any operating system and use nearly any database system supported by Perl and the target OS.
We want this package to be of equal use to the one-man-show as a full accounting package running on a single PC aswell as to large multi-national corporate entities with dedicated accounting servers using the package as a fast stable accounting function, solution or full package.
Main features:
Platform independant
- Wiaflos Accountings core and engine is written in Perl. Perl is an interpreted programming language capable of running on many different platforms including Unix/Linux, Mac, Windows, BSD and many more.
Database independent
- Wiaflos Accountings database interface utilizes the Perl DBI module. This module allows Wiaflos Accounting to access multiple database types transparently, allowing you to utilize the database of your choice, be it MySQL, MSSQL, Oracle, Informix, Sybase or ODBC (or basically anything else).
Folding database transactions
- All modules use database transactions to ensure that if an error occurs everything is rolled back to a safe state. When different modules are integrated to provide functionality like invoicing and purchasing, there are sometimes quite a number of transactions involved which both update, insert and query data. The Wiaflos Accounting database engine automatically merges all transactions during a specific operation into one, this ensures a clean rollback should anything go wrong.
SOAP API (WebServices)
- The interface to Wiaflos Accounting is based on SOAP (Simple Object Access Protocol). The SOAP protocol is a critical communication protocol on the Internet due in large part to the fact that it has become native to so many development platforms, this allows Wiaflos Accounting the maximum benefit of integration and interpolation with other software packages. The SOAP API supports communication over HTTP and HTTPS and includes a full user-based access control system, allowing only certain users access to certain API functions.
Persistent sessions
- Not only does Wiaflos Accounting support SOAP, but it supports persistent SOAP sessions. Authentication is only required once, after that a session cookie is handed to the client application which can then be used in future function calls to authenticate.
Enhancements:
- This version includes support for statements and "balance brought forward" when requesting GL entries.
- Some bugfixes and feature enhancements were made.

Common Media Input Layer (CMIL) is an C++ OO framework designed to improve the state of cross-platform input handling in games and other similar applications.
CMIL was created out of the belief that the methods used in most media APIs perform input handling in a confusing, difficult, inflexible fashion. CMILs goal is to address this issue by establishing a flexible, easy to use, human readible, OO abstraction layer. This layer specifically allows for media and input device abstraction.
Main features:
- easiliy build complex input sequences, including timed inputs, which do not impose restrictive notions of what is and isnt a moderator on the user
- custom input device configurations, IE: Users can swap input device configurations on the fly and create their own representation of a custom device using the framework facilities

iBATIS project provides a very simple and flexible means of moving data between your Java and .NET objects and a relationaldatabase. Use the full power of real SQL without a single line of JDBC or ADO.NET code!

The Data Mapper framework (a.k.a. SQL Maps) will help to significantly reduce the amount of Java and .NET code that is normally neededto access a relational database. This framework maps classes to SQL statements using a very simple XML descriptor. Simplicity is the biggest advantage of iBATIS over other frameworks and object relational mapping tools.

To use iBATIS you need only be familiar with your own application domain objects (basic JavaBeans or .NET classes), XML, and SQL. There is very little else to learn. There is no complex scheme required to join tables or execute complex queries. Using iBATIS you have the full power of real SQL at your fingertips. The iBATIS Data Mapper framework can map nearly any database to any object model and is very tolerant of legacy designs, or even bad designs. This is all achieved without special database tables, peer objects or code generation.

iBATIS Data Access Objects

iBATIS Data Access Objects is an abstraction layer that hides the details of your persistence solution and provides a common API to therest of your application.
When developing robust Java and .NET applications, it is often a good idea to isolate the specifics of your persistence implementationbehind a common API. Data Access Objects allow you to create simple components that provide access to your data withoutrevealing the specifics of the implementation to the rest of your application.

Using DAOs you can allow your application tobe dynamically configured to use different persistence mechanisms. If you have a complex application with a number of differentdatabases and persistence approaches involved, DAOs can help you create a consistent API for the rest of your application.

For Java users, the Data Access Objects framework is bundled as part of the iBATIS Database Layer, which includes the SQL Maps Framework. Although packaged together, the DAO Framework is completely independent and can be used without SQL Maps. .NET users can download the DataAccess framework seperately from the DataMapper framework.

The layer extract plug-in is a Gimp plug-in that creates a new image/film by periodically extracting layers from another image.

It takes one interval (number of sequent layers) every period. The number of periods can be limited.

Swing Glue is an ultra thin layer that allows to decouple view, controller and model into separate individual domains.
It as not just another framework as you might think now. It is an very generic layer that has a minimal impact to the application where swing glue is used.
Main features:
- Object repository that minimizes transport of references
- automatic population of Adhesive class members from the repository
- abstraction of view code and event code
- no wrapping component classes, you still use the normal Swing classes
Swing Glue is proof for the legend that a framewok does not necessarly has to be a Bloat of code that helps you to simplify your development.
It also works with a simple framework that is non evasive and has a very simple code base.
