Where can I get data that is stored in different sources, for example Excel, SQL server, Oracle, etc? I need to build a data warehouse for a university project.
You get data from your different sources thats why they are called sources. There are a few tricks You must get the data out of any proprietary format. So dont attempt to parse an XLS file extract it out to a CSV file (when saving the spreadsheet request that you save it in the CSV format). CSV is ama-separated-view format each field is and separated by ama. This is much more easily parsed by a database loading program like bcp or sql*loader. Use the data loading tools for the database mentioned to load the data into a tables designed to capture this data your staging tables. I am assuming that u do not have access to ETL (Extract Transform Load) tool otherwise you would use that to load staging tables. Finally you will need to design a few reports over your warehouse to show the new design. ordered-list Sounds like a fun project enjoy!!!
Is there a way to find out if a given email address exists?
Here some methods email validation services use to make sure an email address is a safe send or not Spam trap removal identification and removal of email addresses that have a history of being marked as senders of spam. Checking for toxic domains identifying domains that are known for spam and bot behaviour. Detect bounces for emails of which validity is hard to confirm undetectable emails are sent to see if they bounce or not. MTA validation An MTA or Mail Transport Agent is the application that transfers email from one recipient to the other. Email validation tools can check whether the MTA of a particular email address has valid records or not. Email deduplication removing duplicates from your list. Syntax elimination removal of email addresses with invalidbinations. One way to evaluate what the best email validation service is is to check how many and which specific techniques they use to get the job done. However not all services list all of the techniques they use and sadly there also some services that state using particular techniques when in reality they don. The best way to figure out which email validation service is the best is to test it. Looking all over the internet youll find multiple email validation services claiming that they are market leader that they have won awards and that they have the highest accuracy in the industry. In 9% of the cases this is marketers making smoke trying to get you to use their service. The best way to figure out which tool you should use is to test it. You can do this two ways Take a sample that is representative of the email lists you would regularly send emails to. It should be relatively small so you don have to pay a ton to just test it but it should also not be too small so your results can still be fairly significant. Your first test is to check which service marked the most emails as to bounce. In my experience the service that marks more emails as bad is the more accurate one. But not necessarily. To really know which one is best send two separate email campaigns to both verified lists then check for which campaign you have the most bounces. The service that got you the list with the fewest bounces wins. The problem with the first method is that you have to send email campaigns to people for the sake of testing an email validation service. You can also just use a different service every time you clean your email lists and keep track of the verification accuracy. The problem here is that you won beparing results for the same email list. And it will take some time for you to figure out what the service with highest accuracy is. If you don want to spend effort and time testing here my rmendation. In my days as a B2B growth marketer working for multiplepanies I either ran tests like the aforementioned ones or have seen the insights that resulted from it. From those experiences today VoilaNorbert s is my go-to service if I need emails verified. Accuracy is among the highest the pricing is fair you can easily plug it into other processes and software using their API. Plus they have a pay-as-you-go pricing model you upload your list pay for the amount and get a cleaned list in return. No BS with subscriptions or recurring payments. Which I think is smartly done since email verification is not like a monthly need. You do it like once every few months to weed out email addresses that have gone bad.
