Automated source code transformations on fourth generation languages
2004
To control the operation of large application suites or to tailor a special purpose application to particular need, developers frequently use application specific languages, such as batch, scripting, and query languages. These languages which are also referred to as fourth generation languages (4GLs) therefore play an important role in today's economy. Incompatibilities between different versions of 4GLs and changing requirements may make massive changes on a company's library of 4GL programs necessary. Here, we explore possibilities for performing mass changes on 4GLs and show how the transformation of programs written in 4GLs compares to the transformation of mainstream programming langua…
Towards Data Quality Runtime Verification
2019
This paper discusses data quality checking during business process execution by using runtime verification. While runtime verification verifies the correctness of business process execution, data quality checks assure that particular process did not negatively impact the stored data. Both, runtime verification and data quality checks run in parallel with the base processes affecting them insignificantly. The proposed idea allows verifying (a) if the process was ended correctly as well as (b) whether the results of the correct process did not negatively impact the stored data in result of its modification caused by the specific process. The desired result will be achieved by use of domain sp…
Metamodel specialization for graphical modeling language support
2016
Most of current modeling languages are based on graphical diagrams. The concrete graphical syntax of these languages typically is defined informally -- by text and diagram examples. Only recently, starting from UML 2.5, a formalism is offered for defining the graphical syntax of UML. This formalism is based on Diagram Definition standard by OMG, where the main emphasis is on enabling diagram interchange between different tools implementing the given language. While this is crucial for standardized languages such as UML, this aspect is not so important for domain specific languages. In this paper an approach is offered for simple direct definition of concrete graphical syntax by means of met…
Tree Based Domain-Specific Mapping Languages
2012
Model transformation languages have been mainly used by researchers --- the software engineering industry has not yet widely accepted the model driven software development (MDSD). One of the main reasons is the complexity of metamodelling principles the developers are required to know to actually use model transformations in the way the OMG has stated. We offer the basic principles how to create domain-specific model transformation languages which can be used by developers relying only on familiar modelling concepts. We propose to use simple graphical mappings to specify the correspondence between source and target models which are represented using trees based on the concrete syntax of und…
DSL Based Platform for Business Process Management
2014
Currently nearly all commercial and open source BPMS are based on BPMN as a process notation. In contrast, the paper proposes to build a BPMS based on a domain specific language (DSL) as a process notation – DSBPMS. In such a DSBPMS a specific business process support could be created by business analysts. A platform for creating such DSBPMS with feasible efforts is described. This platform contains a Configurator for easy creation of graphical editors for the chosen DSL and a simple mapping language for transforming processes in this DSL to a language directly executable by the execution engine of this platform. The engine includes also all typical execution support functions so no other t…
Metamodel specialization based DSL for DL lifecycle data management
2020
A new Domain Specific Language (DSL) based approach to Deep Learning (DL) lifecycle data management (LDM) is presented: a very simple but universal DL LDM tool, still usable in practice (called Core tool); and an advanced extension mechanism, that converts the Core tool into a DSL tool building framework for DL LDM tasks. The method used is based on the metamodel specialisation approach for DSL modeling tools introduced by authors.
Concrete syntax-based find for graphical DSLs
2020
There are services available in the most software tools we have got used to like, copy, paste, cut, find, and replace. However, the state of the art is not so good with tools of graphical languages. Even many commercial modelling tools have limited support of the find feature. We propose to add find as a service of graphical DSL tool development frameworks. This way find is available in any DSL built using the DSL tool development framework. The concrete syntax-based find has been implemented as a service of the DSL tool development framework ajoo. Two graph-based languages: UML Activity diagrams and Deterministic Finite Automata (DFA) transition diagrams are used to demonstrate usage of th…
Model Transformation Languages and Their Implementation by Bootstrapping Method
2008
In this paper a sequence of model transformation languages L0, L1, L2 is defined. The first language L0 is very simple, and for this language it is easy to build an efficient compiler to C++. The next language L1 is an extension of L0, and it contains powerful pattern definition facilities. The last language L2 is of sufficiently high level and can be used for implementation of traditional pattern-based high level model transformation languages, as well as for the development of model transformations directly. For languages L1 and L2 efficient compilers have been built using the bootstrapping method: L1 to L0 in L0, and L2 to L1 in L1. The results confirm the efficiency of model transformat…
Towards DSL for DL Lifecycle Data Management
2020
A new method based on Domain Specific Language (DSL) approach to Deep Learning (DL) lifecycle data management tool support is presented: a very simple DL lifecycle data management tool, which however is usable in practice (it will be called Core tool) and a very advanced extension mechanism which in fact converts the Core tool into domain specific tool (DSL tool) building framework for DL lifecycle data management tasks. The extension mechanism will be based on the metamodel specialization approach to DSL modeling tools introduced by authors. The main idea of metamodel specialization is that we, at first, define the Universal Metamodel (UMM) for a domain and then for each use case define a …
Domain specific simulation language for IT risk assessment
2011
Information technology systems represent the backbone of a company's operational infrastructure. A company's top management typically ensures that computer software and hardware mechanisms are adequate, functional and in adherence with regulatory guidelines and industry practices. Nowadays, due to depressed economic and increased intensity of performed operations, business highly recognizes the influence of effective Information Technology risk management on profitability. Design of Unified Modelling Language (UML) based Domain Specific language (DSL) described in this paper achieves synergy from in IT industry widely used UML modelling technique and the domain specific risk management exte…
