متن کاملPublishing Your Prototype Tool on the Web PUPTOL, a Framework
We describe an approach to reduce the effort involved in disseminating prototype academic (command-line) tools for wider use and inspection. This helps in preserving the effort involved in the development of such tools, and in raising the standards in computer science for conducting repeatable experiments. For this purpose we propose a light-weight, flexible framework to make such tools availab...
متن کاملPOIESIS: a Tool for Quality-aware ETL Process Redesign
We present a tool, called POIESIS, for automatic ETL process enhancement. ETL processes are essential data-centric activities in modern business intelligence environments and they need to be examined through a viewpoint that concerns their quality characteristics (e.g., data quality, performance, manageability) in the era of Big Data. POIESIS responds to this need by providing a user-centered e...

In Data Warehouse (DW) environment, Extraction-Transformation-Loading (ETL) processes consumes up to 70% of resources. Data quality tools aim at detecting and correcting data problems that affect the accuracy and efficiency of data analysis applications. Source data imported into the data warehouse often has different quality, format, coding etc. In order to bring all the data together in a sta...
متن کاملWerkzeugunterstützung für ETL-Prozesse mit Geodaten (Tool support for ETL processes with spatial data)
Data Warehousing and Spatial Data Infrastructures (SDI) are becoming more and more accepted in public administrations, also in environment administrations and geo data authorities. Hence, the importance of professional ETL (extract transform load) processes for data acquisition, integration, cleansing, and storage is also growing. Though there are numerous ETL tools on the market since many yea...
