Is it possible to create a MySQL Schema from a running AWS-based RDS database? I am a newbie and not sure whether there is a tool like what is available in MySQL workbench type dashboard to create schema at ease?
I am also new to this but I recently created a MYSQL database on AWS RDS.
(I am new to MySQL and AWS).
The answer is yes, we can create schemas. However, as much as I understand, there is no concept of schema in MySQL. There is one database where you create the different database objects and then we just query those using one user or the other.
Edit:: Database and Schema are same thing as per the comments. So yes, we can create schemas and then users to access them.
Anyways, you can use the MySQL workbench to connect your AWS RDS database.
Or you can do the same using any coding language. For both the above options, make sure your database is created with 'Publicly accessible' option enabled.
Refer to this - https://aws.amazon.com/getting-started/hands-on/create-mysql-db/
If you follow all steps, your database on AWS should work like one installed locally on your machine.

Basically the short story is we have a report generator running on a MySQL database at work and management wants me to modify things so we can connect to tables in an external Access database from this report generator as well. And then create reports that join tables from the MySQL database to the Access database. I suggested exporting the data from Access and importing it into MySQL but they want a live, real-time connection. To complicate things further these are both on different servers right now (MySQL on Linux, Access on Windows) and I'm not sure that can be changed.
I tried to look this up online but all I could find is ways to connect to MySQL from Access, not the reverse.
Is what we are trying to do even possible, and if so, can someone point me in the right direction?
I want to use PgSql in my new proyect, but I have old tables I need to use. Which is the best way to share tables between both databases? Is there any way of synchronizing several tables between databases?
You can use SQLWays that convert T/SQL stored procedure, function, trigger, database schema (DDL) and data from Microsoft SQL Server to PostgreSQL.

I'm using MySql Workbench and WAMP Server. I have a database on the server and when I click reverse engineering on the workbench it imports the db structure, but not any of the inserts. What do I do to get the db data as well as the structure into the workbench.
Also on a separate point as I was using workbench, i noticed it did not automatically sync with the db on the server, ie. when i insert a new row, it did not reflect in the server.. must I forward engineer the db to the server every time i make a change? So sorry for my lack of understanding
MySql Workbench reverse engineering is only to obtain the Schema of the database.
If you want to search the database, make backups, obtain the schema and much more then you can use phpMyAdmin. There are some installers which configures the whole system to work with WAMP enviromment and includes it, like Xampp or ZendServer;
could you guys please explain for me HOW these databases ARE CREATED :
mysql
phpmyadmin
information_schema
performance_schema
I know it's a novice question, I might GUESS the answer for some of them, for example "the reason phpmyadmin database is created" IS because I installed phpmyadmin and this database was created alongside . That's not for sure, so I just need some clarification.
Thank you !
Mysql is a database server. It serves access to databases. It runs on a machine as a service.
Phpmyadmin is a php based tool you install for managing mysql from a web page.
The last two are databases that can be created by an application, such as phpmyadmin, for storing schema information about the rest of the database or tables of a database.
These are the standard set of databases shown when you execute SHOW DATABASES on a clean MySQL install.
mysql - this is created at install of the MySQL server, either by the package management system of your operating system or the script provided as part of the MySQL package
information_schema - meta database, it does not exist on the disk
performance_schema - meta database, but it does store some files on the disk
Any other databases are user/application created.
i have 3 servers for three applications on aws ec2 using MySql database,
now each of the application is having amember that is client subscription app,
it connects with sql databse that is created in each instance
so in this way every amamber app is having diffrent database in each server,
now we are working with a device ROKU we need to pass the XML attributes from amember to it
to varify the user so he can watch online streaming tv.
the objective
now i need to make one database that will be connected with each server using amember
so each server access one database .
Options
my options are aws RDS ,dynamoDb
Now can anyone put me in the right direction, for that.
in simple Words
need to connect my multiple apps (same app) with one database
HELLLLP
If you need to connect to a mysql database, DynamoDB is not the answer. It isn't a mysql database.
RDS is a mysql database. It connects like any other mysql database. You haven't mentioned what language[s] you are using, however. Googling "connect to mysql with [language]" should help.
I think it would be best to stick with relational databases such as MySQL.
Amazon RDS is a managed MySQL solution, but you don't have to use it for your needs.
You can use one of your EC2 instances or a new EC2 instance as the central DB and connect all the other servers to it for quires. There are pros and cons for choosing RDS over your own SQL server. If you have any questions there, feel free to edit your question and add them.
EDIT according to comment
In order to connect your application with the local MySQL. Your are probably using a connection string that points to either "localhost" or "127.0.0.1"... That is the IP of your local machine. You will have to change it to the remote IP of the machine where the DB is stored remotely.
