I want to fetch database schema or structured with foreign key reference, like phpmyadmin present or shows. For this I am using nodejs technology. I'm trying to identify best solutions but not found. Some articles suggest to use jdbc.
Can you please suggest me how to fetch database schema or structured.

I am building a multi-tenant backend using Node, Express, PostgreSQL and Sequelize. All of my tenant's data is stored in the same table. Right now, I am using the WHERE clause to filter data and restrict one tenant's data from others but I would like to add another layer of security using the row-level access control feature of PostgreSQL. I found this article very helpful but it does not cover the implementation in NodeJS.
I am trying to make a simple website in VanillaJS. I don't want to do much work on the backend so is there a way to connect your MongoDB database to VanillaJS? I have searched it many times but I can't find an answer to this. Thanks in advance!

Connecting MongoDB to the front-end?
#Philipp:
MongoDB isn't designed to expose data directly to the client.

I think you can use the cloud services provided by the databases (Like Mongodb Atlas). MongoDB Atlas API
Client-side JS does not provide any apis for connecting any kinds of DB, it means your DB connection including username and password will be exposed, which means anyone can access your DB.
If you want to have a DB running and with some apis, may try firebase?
yes firebase can be used in vanillaJS. but having hardtime finding ways to mimick "LIKE %" when querying.
I am trying to understand if an e-commerce website without database, built with node.js would still have the capability to produce a passive Data Dictionary?? Is a database mandatory to produce a data dictionary?
Thanks a lot for your help!
You probably need to have a database in order to build an e-commerce website. Because the data dictionary may just include a summary (column names, types, etc.) of the tables in the database. Actually it is just a repository of information about data in a database or a data set.
I have created a mySQL database at a Host IP, but now wish to use GraphQL to make queries easier from the front-end. I've know how to set up a GraphQL server from scratch, but was unsure how to access my pre-existing tables at the back-end, and where to define the schema to use them. How would I connect to the database from a GraphQL server?
Prisma was an option I considered, but the service doesn't allow connections to mySQL databases which have pre-existing data.
Thanks for the help!
Prisma and other ORMs are a good option if you want a relatively easy/cheap way to expose CRUD operations for your entire database.
If you only need to expose specific aspects of your data or just need to start iterating quickly, you can define your GraphQL API schema at the server level and write resolvers that connect to your database as needed. Your schema does not need to reflect your entire database, but only the data you'd like to expose to clients.
In my experience with GraphQL APIs, I've found that manually writing query schemas and creating resolvers as needed for servicing the client is both faster and easier to maintain for smaller applications.
You can use a SQL client like https://github.com/mysqljs/mysql to interface with your database. The resolvers you write for your schema would then query your database for any data needed to serve the client's request, even if it spans multiple tables.
The GraphQL spec learning site graphql.org has a good description of this process https://graphql.org/learn/execution/#root-fields-resolvers
You can try a new open source tool called SwitchQL (github.com/SwitchQL/SwitchQL). I've been working on the project for a while.
You pass it your connection string and it returns everything you need to run a graphql server on top of an existing database. It also returns Apollo compliant client mutation and queries.
We only support Postgres at the moment. If you end up trying it out, please let me know what you think!
They have a database of all schema data that they've collected from websites. Like they know what concerts are going on around me. Is there any way that I can access that database? Whether it be through an API or some sort of script.
