[選]工作要求：（若未提供請勿刪除）
[選]參考段落：
2. Data collection: Once the goal of exploration is determined, user can start collecting or extracting
relevant data from data source, regarding to exploration target. Mostly, data collected from disparate
systems are appeared unorganized and diverse in format. No need to say, original data might be from
different sources, such as files, database or Internet. To retrieve data from these sources requires the
assistance of file IO function, JDBC/ODBC, or web crawler etc. These extracted data at the first
hand are called “raw data”, which is because they have not been subjected to processing, or being through
any other manipulations. As is known, most raw data are not easily consumed for most of analysis tools or
visualization programs.

3. Data munging: Then, it comes to the phase of data munging (or wrangling), a step for helping to map raw
data into more convenient consumption format. During this phase, there are involved with data parsing,
sorting, merging, filtering, missing value completion, and other more processes to transform the data into
organized, and enabled them to fit in consume structure. Later on, the mapped data can be further utilized
for data aggregation, analysis or visualization.
