Boost your Linc to Java migration
Energize and convert Linc applications by migrating away from legacy Unisys technology to J2EE! With its proprietary Freedom® automated technology, ArtinSoft will take care of your Linc to Java conversion project easily and securely, allowing you to take advantage of the robust, modern, and open Java platform. ArtinSoft offers a comprehensive solution designed to meet your Linc migration needs so you can leverage new and powerful Java features within your applications, lowering maintenance costs and expanding your service offering. With a Linc to Java conversion, you will enjoy improved development productivity through an object-oriented, component-based development model, including simplified integration with heterogeneous environments and other applications.
Linc vs. Java - migration benefits:
| Monolithic application |
Multi-tier application, clearly separated across its functionality boundaries
|
| Proprietary technology (hardware and software) |
Open platform with a wide range of suppliers |
| Limited human resources |
Extensive availability of programmers |
| Integration with other business applications is not native |
Easy integration of services, as a result of SOA |
| Limited scalability, tied to high financial costs |
Scalability is one of the main pillars of J2EE |
| Rigid, proprietary database |
Relational database that provides query mechanisms and relational integrity |
| Limited access to new technologies |
Easy integration with modern technologies, like SMS, Mobile and Web |
So move away from Unisys’ Linc and step into the future! Our highly-automated migration process will convert Linc code to Java successfully by using a relational database as a persistence mechanism. The standard Java 2 Enterprise Edition (J2EE) defines a series of technologies and logic tiers where the software components that make up an organization’s corporate application are located. In Linc, an ISpec can define aspects such as the screen, a database structure and the business logic as a response to an action by the user. Figure 1 shows the correspondence of the general elements of Linc with those of J2EE.
How it Works
Our complete, turnkey solution generates the following J2EE tiers from Linc:
| Client tier |
Each ISpec of type Input or InputOuput becomes an HTML page that the user has access to. Additionally, elements such as a "Cascading Style Sheet" (CSS) are used to obtain a more configurable interface. To achieve a greater efficiency and provide a better experience for the end user, Java Script libraries are generated to perform tasks such as the validation of required fields. |
Web tier
|
Each ISpec of type Input or InputOutput generates a JSP component, which is responsible for dynamically generating the HTML screen that is displayed to the user. Java Standard Tags Library (JSTL) is used to generate this JSP. |
Business tier
|
Each ISpec of type Input or InputOutput generates a Java class which contains the business logic defined in the ISpec as methods of this class. This class extends the GenericProcess class (provided by ArtinSoft), which is in charge of providing the necessary functionality to execute the migrated code in the same way as defined by the Linc cycle. Additionally, the business tier generates a Stateless Enterprise Java to implement the Façade pattern. This EJB determines which generated Java class must handle the request, and moves the execution of the control to that class. |
Database access tier
|
For each ISpec of type Output or InputOutput a class is generated that encapsulates all access and operations with the database. This class enables the implementation of the Data Access Object pattern. The methods to access the database are generated automatically based on the information provided by the Determine and Look.Up commands along with the defined Profiles. |
Relational database tier
|
The general model for the migration of the database consists of 3 phases:
- Generation of the relational database. The table creation scripts are generated automatically by the data migration tool using the Linc source code.
- Data extraction. The tool generates reports in Linc from the ISpecs of type Output and InputOutput that allow stored information to be moved form the DMSII database to plain text files.
- Population of the relational database. The plain text files are imported to the database using tools such as Oracle SQLLoader or DB2 Load.
