Often the real meaning and potential impact of a database can be hidden behind all the raw names and numbers, but a well-chosen visualization can bring the data to life. Google fusion is a cloud based application from Google where you can share and visualize data online. You can visualize data in a number of forms like: Map, Intensity Map, Bar, Pie chart, Table, line etc.
Yesterday Google released the Fusion API which will help to update and query the dataset programmatically, without ever logging in to the Fusion Tables website. The API means you can import data from whatever data source you may have, whether a text file, spreadsheets, CSV or a full-powered data base. Currently due to labs release, it supports up to 100MB per table, and up to 250MB per user. You can export your data as csv too. Once you viewed your data in desired visualization form you can integrate it in your website, blog or any web page.
You can also merge your data with other datasets uploaded by users to get whole new meaning to your data. There is a provision of embedded comments to discuss about data with other users. Fusion Tables keeps track of who contributed each part of the data and who has permission to edit.
Open Data Kit uses Google App Engine and the Fusion Tables API to instantly map locations of survey results. It is use for collecting data via survey software on GPS-enabled cell phones. Collect is built on the Android platform and can collect a variety of form data types: text, location, photos, video, audio, and barcodes.
