Data acquisition journal

Data acquisition has been understood as the process of gathering, filtering, and cleaning data before the data is put in a data warehouse or any other storage solution.
The acquisition of big data is most commonly governed by four of the Vs:

1. volume
2. velocity
3. variety
4. value

Journal of Data Acquisition and Processing is responsible for China Association for Science and Technology and is issued at home and abroad, which is sponsored by Nanjing University of Aeronautics and Astronautics and Chinese Institute of Electronics.

Data acquisition can be divided into two parts:

1. acquisition and preprocessing
2. which is just narrow data acquisition

From a data acquisition perspective means for stream data computation are necessary, which can deal with the challenges of the Vs of the data.
In order to bring a benefit for the transportation sector (especially multimodal urban transportation), tools that support big data acquisition have to achieve mainly two tasks (DHL 2013; Davenport 2013 ).
