Build Database to Store & Extract Data from Text Files (Easy $$$)
预算 $100-320 USD
NOTE: I originally hired someone for this project and he got called away. Below is the basic scope of work needed. I also included some of the comments from the original developer. You may have a better idea. Speed is important… very important.
My goal… load email list into a database and extract all of the email addresses that have the same email domain as a URL in my domain list.
Example domain
[login to view URL]
[login to view URL]
[login to view URL]
Example text string
chris,jackson,chris@[login to view URL],1234567897
billy,bob,bbob@[login to view URL],84881451
john,doe@[login to view URL],8814
Example saved results
chris,jackson,chris@[login to view URL],1234567897
john,doe@[login to view URL],8814
I am looking for any line that has an email that matches the domain. So if I have [login to view URL] it will extract every line where there is a @[login to view URL] email address. Domains are one per line.
In my list I will have [login to view URL] but when it is being searched, you will code it to search for @[login to view URL] to ensure it pulls a valid email format and not ‘email@[login to view URL]’.
IMPORTANT
Once the Source files are imported into the database there will be around 2 billion records. Many duplicates. I have a list of 400,000 domains that I want to scan against it. I do not expect this to be completed in a few minutes but I do not expect it to take days or weeks. One of the ways we can speed up the Search process is by allowing me to load a suppression list of domains that I do NOT want to import into the database (Gmail, Hotmail, Yahoo). It may be best to have this as a list that I paste into directly into the database so that it doesn’t bring this data in. This will hinder the Import speed but it will speed up the Matching phase since most will be free email accounts.
NOTES
-- The Source files are .csv files that I renamed to .txt for this purpose.
-- Some files have 1 column, and some have 3, 4, etc. Instead of trying to build a table to match the columns, we will treat each row as a single text string (as a single column) and import the entire row of data.
REQUIREMENTS
-- The results need to save frequently instead of waiting until the task is complete.
-- It must have a basic UI – no commands. I want to be able to click a button to run Import and click a button to Match.
-- When I click Match, it asks me to select the [login to view URL] file. This is the file that has the URL’s I want each email address to include.
-- Speed is very important. Speed matters in two parts – the initial import of data and the matching of Domains against the email list.
DEVELOPER NOTES
Here are some key points from the previous developer who started it.
-- Use C++
-- with some precomputation and indexing we can save a lot of time
-- your issue looks mainly like an indexing issue, if you'll index emails with domain name you -- won't have to go through all data every time you search
-- I talked with the DB Admin, and we are using nested Queries
I cannot waste any additional time on this so I must ensure that you have read the details or I’ll flag your bid. In your bid, include the following the quoted text in the first line “I reviewed the notes and understand that speed is important to you.” To help me understand that you are the right person for the job, let me know how soon you can start, when you can finish, and how you plan to develop. The more detail you provide, the more confident that I am that you are the best choice.
Make your best bid first as I will not be overpaying for this task. Do not bid the maximum budget amount as my max is lower than that.
Thanks!
