Data collection may be a one-time action or a regular routine. In the first place, data processing services include data collection by means of web scraping, downloading, retrieving through API, or querying a database.
The second situation is when you have a lot of raw, untidy data that your data analyst cannot easily work with. For instance, if you plan to conduct marketing research but do not possess any competitor or pricing data yet, you will need data processing to collect market data. In the first, you may not have any of the data that you need to answer a business question. Since data processing involves gathering and cleaning data, there are two primary situations in which you need this kind of service.

Data processing focuses on data sources and how to get data quickly and without high expenditure.
Although it may also include a short analysis, the main focus lies on different methods of gathering data that do not originate in your business.ĭata processing involves the collection of data in a systematic manner or in large quantities. Sorry about that.Data processing refers to a stage preceding data analysis and includes data collection and preliminary preparation. The Next button is disabled when I reach the last page, but PAD still sees it and keeps banging on it like a cop trying to serve an arrest warrant.įor this I may have to first find the 'Next' element, move to the first button to its left, extract the text on the button, put that in a variable, and then set the max number of web pages to that I get the sinking feeling I'm not helping you much here. Perhaps my 'all available' problem is due not to anything in PAD, but on the web page. So that gets rid of the non-extraction problem. I'd be interested to know if anyone else has that problem. I've been unable to get the 'live web helper' to re-select the pager element from the context menu, so I've added it as a CSS selector manually in advanced settings. I also discovered the pager element had disappeared from the 'Advanced' settings, which was part of my problem. Frustrating though, and sounds like something similar to what you're dealing with.ĮDIT: I have partial success now, but only partial, with the extraction set to 'only the first page' and the max number of pages set to 4 (why does that even work?). The page was created with Angular, which may be part of the problem, I don't know. Second, less frequently, it extracts everything but keeps banging the 'Next' button, and will not stop, regardless of what error settings I try. But it is what it is.įirst, it usually just fails to extract the table. Shouldn't this be something like 'all available' with another field for 'up to a maximum of', or similar? I'm stumped. Here's what I get - why is there no field for max pages here, where it belongs? Now I have to set the extraction differently. In this screenshot I use 'Next' for the pager. Why on earth is there an option for max web pages to process if it's set to 'Only the first'? Anyway, for a single page it works.
I get two different sets of problems, depending on the run. At the bottom of the page are the numbers 1 through 4 for the pages, then a 'Next' button, then a 'Last' button. I have a site with tables, 20 rows per page.
