Towards a Low Cost Etl System
Data Warehouses store integrated and consistent data in a subject-oriented data repository dedicated especially to support business intelligence processes. However, keeping these repositories updated usually involves complex and time-consuming processes, commonly denominated as Extract-Transform-Load tasks. These data intensive tasks normally execute in a limited time window and their computati...

متن کاملTowards a Benchmark for ETL Workflows
Extraction–Transform–Load (ETL) processes comprise complex data workflows, which are responsible for the maintenance of a Data Warehouse. Their practical importance is denoted by the fact that a plethora of ETL tools currently constitutes a multi-million dollars market. However, each one of them follows a different design and modeling technique and internal language. So far, the research commun...
متن کاملTowards a Safe, Low-Cost, Intelligent Wheelchair
Unlike most other robots, autonomous personal transports must be designed with a passenger user in mind. This paper examines the integration of three necessary technologies for a robotic transport—in particular, a robotic wheelchair. First, local motion to a nearby goal pose needs to be safe and comfortable for the human passenger. Second, 3D overhangs, drop-offs, steep inclines, and stairs (in...
متن کاملMicroraptor: a Low-cost Autonomous Quadrotor System
This paper describes Microraptor, a complete low-cost autonomous quadrotor system designed for surveillance and reconnaissance applications. The Microraptor ground station is custom-made and features a graphical user interface that presents and allows the manipulation of various flight parameters. The aerial vehicle is a 4-rotor vertical takeoff and landing (VTOL) vehicle that features the adva...
