NOSQL vs SQL RDMS for trading data
I got this question from a member:
When storing my stock data, would it be better to use a NOSQL or SQL server I am a MS Partner so I receive $100 monthly credit for Azure services and it looks like a promising option. They have DocumentDB as well as SQL server options both on high bandwidth connections, I could run my IQFeed client on a compute node and just query database from mobile and desktop connections, but not sure which option is better for stock data.
I am unsure of your exact goals in terms are you using this for analytical real time purpose or to house data, If you are using for real time in a high frequency timeframe, use NOSQL with something like MongoDB or Redis. If you are using for historical or to permanently house (like a data warehouse), use a database like SQL Server. In terms of cloud, if the data is not sensitive, it can be useful.
As for me, I want to live in a non Windows world one day so I my modern open source database of choice is PostGres for now. It has worked as well as my experience with SQL Server plus PostGres is free as you know.
Hope this helps for now,
