| Abstract: |
The Data Analysis Center for Exoplanets (DACE) is a web platform based at the University of Geneva (CH) dedicated to extra solar planets data visualization, exchange and analysis.
This platform is based on web technologies using common programming languages like PHP and JavaScript for the front-end part and Java or python on the back-end. Cassandra, PostgreSQL and MongoDB are used as database management systems.
The DACE tools required to download a large amount of data from the databases. In order to keep the load of data as fast as possible, a lot of optimizations has to be done on the client side to improve the user experience. The platform should be use from remote places in the world with a low speed internet connection.
The download of the web pages is optimized by minimization of the code and client side HTML building. The visualization of data on DACE is using a lot of optimisations in case of big data display, in order to provide interactive charts in short time but with faithful representation. The data download is optimized by using binary messages and object-oriented structures.
The DACE platform is funded by the Swiss National Centre of Competence in Research (NCCR) PlanetS, federating the Swiss expertise in exoplanet research. |
