What's data collection
"Data collection is the process of gathering and measuring information on targeted variables in an established systematic fashion, which then enables one to answer relevant questions and evaluate outcomes." (Wikipedia) The goal for all data collection is to capture quality evidence that then interprets to rich data analysis and permits the building of a convincing and credible answer to questions that have been displayed.
Many companies need to extract data from websites to meet their various needs. But during the process of collecting data from websites, they may run into some problems like collecting irrelevant or duplicated data, insufficient time or budget, lack of useful tools or having difficulty collecting dynamic data.
Data collection methods
When collecting data from the web for your own use, a useful tool that helps you get what you want exactly in a short period and extract data on a scheduled basis will greatly increase your efficiency at work. It takes time for companies staff to gather information from websites by just copying and pasting or using data collection software which require more or less coding experience. With help from data collection and analytics tools, organizations are also able to collect data from mobile devices,website traffic, server activity and other relevant sources, depending on the project.
Big data and data collection
Big data describes voluminous amounts of structured, semi-structured and unstructured data collected by organizations. Big data includes issues that involve such massive data sets and solutions that need a complex connecting the dots. It takes a lot of time, effort and money to collect a huge amount of data in a traditional way. Thus new approaches for collecting and analyzing data have emerged. From there, machine learning and artificial intelligence programs use complex algorithms to look for repeatable patterns for data collection.
