Automatic Generation of Data Merging Program Codes

Data merging is an essential part of ETL (Extract-Transform-Load) processes to build a data warehouse system. To avoid rewheeling merging techniques, we propose a Data Merging Meta-model (DMM) and its transformation into executable program codes in the manner of model driven engineering. DMM allows defining relationships of different model entities and their merging types in conceptual level. O...

METL: Managing and Integrating ETL Processes

Companies use Extract-Transform-Load (Etl) tools to save time and costs when developing and maintaining data migration tasks. Etl tools allow the definition of often complex processes to extract, transform, and load heterogeneous data into a data warehouse or to perform other data migration tasks. In larger organizations many Etl processes of different data integration and warehouse projects ac...

Merging DEL and ETL

This paper surveys the interface between the two major logical trends that describe agents’ intelligent interaction over time: dynamic epistemic logic (DEL) and epistemic temporal logic (ETL). The initial attempt to “merge” DEL and ETL was made in [12] and followed up by [11] and [29]. The merged framework provides a systematic comparison between these two logical systems and studies new logics...

Systematic ETL management - Experiences with high-level operators

Large organizations load much of their data into data warehouses for subsequent querying, analysis, and data mining. Extract-Transform-Load (ETL) workflows populate those data warehouses with data from various data sources by specifying and executing a set of transformations forming a directed acyclic transformation graph (DAG). Over time, hundreds of individual ETL workflows evolve as new sour...

Requirements Analysis Method For Extracting-Transformation-Loading (Etl) In Data Warehouse Systems

The data warehouse (DW) system design involves several tasks such as defining the DW schemas and the ETL processes specifications, and these have been extensively studied and practiced for many years. The problems in heterogeneous data integration are still far from being resolved due to the complexity of ETL processes and the fundamental problems of data conflicts in information sharing enviro...
