Rational Programming Patterns for System z

• Vylepšuje IBM Rational Developer for System z a IBM Rational Team Concert ďalšími novými funkciami, ktoré sú prispôsobené paradigmám vývoja Pacbase na základe vzorov.
• Vzory popisov údajov pomáhajú ovládnuť informačný koncept IT systému vo forme, ktorá je pochopiteľná pre špecialistov podnikových domén a použiteľná pre vývojárov softvéru.
• Programovacie vzory pre tradičné aplikácie poskytujú sadu modelov vyhradenú na zaznamenanie podstaty bežnej architektúry mainframových aplikácií za účelom posilnenia produktivity vývojárov.
• Makroštruktúrne vzory poskytujú mocnú a výraznú schopnosť opakovaného využitia logiky v programoch, znižuje komplexnosť pomocou zapuzdrenia a súčasne umožňuje údržbu prostredníctvom jediného miesta.
• Mikrovzory COBOL sa podieľajú na zvýšení produktivity vývoja, sú výkonným nástrojom na vloženie skupiny či niekoľkých skupín vygenerovaných riadkov v jazyku COBOL do programu COBOL, pričom nahrádzajú pozitívne komplexné operátory Pacbase a zabezpečujú produktivitu vývojárov pri vkladaní podnikovej logiky do generovaného zdrojového kódu.
• Rozšírený editor zdrojového kódu COBOL uľahčuje údržbu užívateľsky špecifického kódu v generovanom zdrojovom kóde tým, že optimalizuje úlohy, ktoré musí vývojár spravovať v generovanom zdrojovom kóde COBOL (napr. filtre, sprievodcov, zvýrazňovanie syntaxe, asistenta obsahu, kontrolu syntaxe v reálnom čase a interaktívne ladenie).
• Analýzy dopadu a vyhľadávanie na základe viacerých kritérií sa ako rozšírenie služieb Rational Team Concert Repository podieľajú na zvýšení produktivity údržby tým, že zachovávajú jedinečnosť popisu informačného konceptu.
• Rozhranie s externými správcami SCM ponúkajú flexibilný časový rámec na prispôsobenie aktuálnych procesov nasadzovania aplikácií, pretože poskytujú procedúry určené na extrakciu projektov alebo komponentov z IBM Rational Team Concert SCM za účelom ich importu do externého SCM.
• Generujte zdrojový kód COBOL, ktorého syntax je rovnocenná zdrojovému kódu COBOL generovanému vo VisualAge Pacbase verzia 3.5. V spojení so skupinou porovnávacích nástrojov na kontrolu toho, či migrácia prebehla správne, táto funkcia drasticky znižuje počet prípadov neregresného testovania, ktoré sú potrebné po dokončení migrácie a ktoré predstavujú najdrahšiu časť projektu migrácie.

IBM Rational Programming Patterns for System z enhances the set of development/delivery tools of IBM Rational Developer for System z and IBM Rational Team Concert with additional new functionality adapted to the Pacbase Pattern Driven development paradigm for the development and the maintenance of applications that have been developed with VisualAge Pacbase v3.5.

IBM Rational Programming Patterns for System z addresses the full spectrum of traditional business application requirements including the following features:

Data description patterns help to master the information concept of an IT system

Data description patterns enable the encapsulation of concepts that make up the IT systems in a form that is understandable by a business domain specialist, and yet is also consumable by those whose main expertise is software development. This abstraction improves the capabilities to control and administer the semantic of an IT system and to reuse the enterprise information concepts in all the components of an IT system.

Copybook definitions are supported by the Data description patterns to generate COBOL copybooks for the following targets:

Database definitions are supported by the Data description patterns to generate Database schemas for the following targets:

Programming Patterns improve the development productivity for traditional applications

Programming Patterns for Traditional applications improve the development and maintenance productivity of the developers by providing a set of models that capture the essence of the common architecture of mainframe Batch and Transactional applications. With these patterns, a developer focuses on the business logic rather than the structure of the program and the complexity of the technology. An organization adopting this development paradigm streamlines COBOL development because Pattern Driven Programming allows for accurate and predictable work estimation, consistent code performance, high quality generated code, as well as guaranteed homogeneous coding styles, algorithms and structures across many programs.

Batch program definitions are supported by the Programming Patterns for traditional applications to generate Batch transaction processing and reporting applications with their error handling resources for the following targets:

Online program definitions are supported by the Programming Patterns for traditional applications to generate Textual User Interface applications with their error and end-user help handling resources for the following targets:

Macro-Structure Pattern automates the implementation of the architectural standards of an organization

Macro-structure Pattern provides a powerful and expressive capability for reusing logic among programs. It minimizes complexity through encapsulation while providing a single point of enhancement, modification applicable to all programs calling a macro-structure pattern. The code written in a macro-structure pattern includes substitution parameters that are resolved when included in a given program.

Macro-structure Pattern is a first-class tool to extend and adapt the standard generated source code with the architectural standards of an organization.

COBOL Micro-Patterns contribute to increase the development productivity

A COBOL micro-pattern is a powerful way to insert a group or several groups of generated COBOL lines in a COBOL program. A COBOL micro-pattern is identified by an annotation with parameters used by a dedicated generator to insert COBOL source code usually after the location of the annotation in the COBOL program.

As Rational Programming Patterns for System z requires to use native COBOL code to add user-specific code in a generated program, the COBOL micro-patterns replace favorably complex Pacbase operators, preserving the productivity of a developer when he has to insert business logic in a generated source code.

In addition, the Micro-patterns scope that enhance the capablity of PDP with micro-generation features has been enlarged with new operators, and also the capability to define new ones, through specific wizards that help to create micro-patterns plug-in. Java APIs include in the Model Access Facilities (MAF) framework allowing navigation in the entities instancies can be accesses from user micro-patterns.

Extended COBOL source code editor facilitates the maintenance of user-specific code in the generated source code

IBM Rational Programming Patterns for System z extends the Rational Developer for System z COBOL source code editor (LPEX) to optimize the tasks a developer has to manage in a generated COBOL source code. New views, filters, wizards and COBOL lines colorization actively support the developer in addition of the first-class functions provided by the standard System z COBOL source code editor such as content assist, real-time syntax check, interactive debugging. All these tools keep, even improve, the development productivity of a Pacbase developer.

Impact analysis and multi-criteria search contribute to increase the maintenance productivity

IBM Rational Programming Patterns for System z extends the Rational Team Concert Repository services to provide impact analysis and multi-criteria search dedicated to the development artifacts migrated from Pacbase. Search can combine various technical or semantic criteria to help a developer to keep the consistency of the IT system descriptions, to preserve the uniqueness of the description of an information concept and by the way to make reliable the result of an impact analysis query, improving the maintenance productivity of the developers.

Interface with external Software Configuration Managers provides a flexible time frame to adapt current application deployment processes

IBM Rational Programming Patterns for System z provides procedures to extract projects or components from the IBM Rational Team Concert SCM to import them in an external SCM. This feature allows an organization to quickly take advantage of the latest collaborative application life cycle management technology provided by IBM Rational Team Concert while using some deployment processes attached to an external SCM when it is needed.

Migration from VisualAge Pacbase v3.5 at low cost

The generators provided by IBM Rational Programming Patterns for System z generate a COBOL source code syntactically equivalent to the COBOL source code generated by VisualAge Pacbase v3.5. This generation capability, in conjunction with a set of comparator tools to check that the migration went well drastically limits the amount of non-regression test cases needed post-migration,representing the most expensive part of the migration project.

IBM Rational Programming Patterns for System z v8.0.3 introduces major enhancements in Pacbase export procedures (MIAM, MIBA, MIBR, MIMA, GPR9, MIAx) as well as import procedures that helps both to improve analysis capabilities before and after the migration (error-prone entities list, COBOL source comparison tool), and to automate several steps during migration (procedures inputs and batch command files generation). Batch migration tool (RPP.BAT) performance and usage mode has also been extended to improve migration performance.

Improve development productivity with pattern customization

IBM Rational Programming Patterns for System z v8.0.3 helps improving the application development lifecycle productivity by providing the capability to extend and customize standard patterns according to specific needs through storage and edition common services, and also a service API to navigate inside the model instances in the local workspace. Migration facilities for existing Pacbase specific patterns - also known as Meta Entities and User Entities - is also provided, just like for standard patterns.

Just like standard entities, User Entities and Meta Entities are stored in the Rational Team Concert Repository take benefit of all Repository Services like multi-criteria search and impact analysis and can be accessed by default editors through new entity types in the Design Explorer View.

Maintain Pacbase inheritance maintainability through quality rules

IBM Rational Programming Patterns for System z v8.0.3 helps to address risks linked to coding style diversity inside a development organization or their partners by enforcing compliance to development standards and ensuring code homogoneity, preventing that way poor code quality and performance issues detected late in the developments lifecycle, inducing higher correction costs.

Quality Control capabilities aim to provide a basic set of quality rules to control both specific code sections and patterns by using the new capability of Rational Developer for System z v8.0.3 to implement code quality rules as an extension of existing syntax check capabilities.

Develop and deploy applications for various platforms

IBM Rational Programming Patterns for System z v8.0.3 now provides a single environment for heterogeneous languages like Microfocus and BULL GCOS-7 COBOL targeting Windows, AIX, HPUX and BULL G/COS-7 operating systems, for which editing and code reconciler capabilities have been extended. The Pattern Driven Programming (PDP) features works with the Rational Developer for zEnterprise 8.0.3 editor, but without the Syntax Check feature for the Microfocus and G/COS-7 targets, as the reserved words of non-IBM COBOL languages are not supported by the editor.

IBM Rational Programming Patterns for System z supports migration from VisualAge Pacbase 3.5 V07, or later. Refer to the Migration section below for more details.
