I am considering using Form.IO Open Source which would be installed on AWS as the front end of an existing app that has a postgress dB.
I am very new to this and I can not tell if you can use the resquel library allows you to map the form responses directly to a SQL database or does it map the form response saved to its mongo database to a SQL database?
I really do not want to use the Mongo DB at all and am hoping that form responses can be mapped directly without saving to a Mongo DB
Any insight into this is greatly appreciated
thank you

I have millions of records in postgresql table.Using Ado.net i have taken all the records that record how can i dump into Neo4j using c# .I am new to Neo4j user if any one knows help me .Thanks in Advance
i am new to Neo4j user ,could you please refer any link/examples
I'm using node as backend for my application. And postgresql as database. For accessing database I'm using Prisma But now I'm really worried about the DB hit on each API calls. So is there any method to find number of queries passed through prisma client or to see the queries. Or Should I need to log anything in my postgresql for that?
I have not found real sync from postgreSql to new graph database like neo4j, so I've decide to use same postgresql to sync one normalise tables with json table on the same postgresql with a differenta name for a database. So i have the best of two worlds, sql and nosql database.
When i see sql is more fast than graphql i can choose, and in the future, when i moved the nosql tables to a real graph database like neo4j and i ll be able to sync, i dont need to change the app that can use both database synced
Someone did already this? or it's a dumm idea? Or someone already use automatic libraries to sync from postgresql to neo4j ? and the another sens too ? or must I write sync scripts from scratch if i want to sync two databases?
I have created custom script in Express that actually migrates SQL Server database to MongoDB.
But I am facing problems in live syncing between the two databases.
Currently I have added a column updated_by in both the databases.
Then I fetch the latest updated_by row from MongoDb and SQL Server database.
Then I check the date difference and based on it I update my MongoDB database.
There are lots of db tables and I am finding it difficult to identify that, which table is being updated.
Is there any log in SQL Server 2008 R2 that states which table is updated and at what time?
I need a mechanism like, any data update in the db table should immediately sync that rows into my MongoDB.
Any more suggestions on live data syncing is also welcome.
Thanks in advance. :)
When i have such requirement to Sync between Relational DB say (MYSQL) and Non-Relational DB (Mongodb).
I had followed following steps which may help others in future. and the concept is generally called as Change Data Capture
Capture changes (For MYSQL iam using triggers.)
Transform changes to a suitable changes
ie RDBMS to Non RDBMS
Update changes
Remember to sync the structural changes of database and corresponding implementaions.

I do not have much experience in postgresql but would like some clues on how to do the following:
I intend to feed a DB PostgreSQL/PostGIS through data that are in Informix DB, which I have access via ODBC.
In short, I intend to do a "select" in Informix DB and be able to import that information directly into a DB PostgreSQL/PostGIS.
From what I understood it seems possible to do it via DBLink. Is that so?
Where can I get detailed information about this process?
I would suggest dump the data from whatever DB you have in text format like CSV, then use COPY command to load the data into PostgreSQL.
