updatetools v0.2.7

updateTools

This library is designed to Read & Write Crypto Currency historical data to and from a Mongo Database

The DB functions often call the cbxQuery library that I created to read the data from the coinbase api located at:

"https://api.pro.coinbase.com";

The functions that are the heart of this libary are:

• DBcollectionList- is used to get a list of collections from the mongo database.
• DBproductExist- is a simple check to see if a specific product exists in the mongo database.
• DBmostRecentDate-look to see when the last update was run by finding the most recent data for a specific collection.
• DBfillBlanks- when the server was off for a period of time, it creates blank spots in the data. To make analysis simpler We fill these blanks with zero volume and whatever the last value was for price.
• DBpatchBlanks- Sometimes blank spaces are due to download errors, this routine tries to re-read the data to fill in missing points
• DBrecordCount- Count how many records are in collection
• DBupdateCollection- Update the collection for a single collection
• DBupdateCollections- get the list of all collections and up date each one of them.
• DBupdateSet- This function actually write the data to the server
• DBpatchCollection- patch all missing data for a collection

To use this library, I created a mongodb Atlas

I named the Database: coinbase And created empty collections with names such as:

• ADA-USD
• BTC-USD
• ETH-USD

There is a another tool that calls this code to run updates for all of the data. It starts out empty, but the database fills quite rapidly
