EF7 claims to support lots of providers, but I'm having trouble finding documentation about which ones currently exist. I'm particularly interested in MySQL and Postgres providers.
ATM EF7 still under development, currently it only support SQL Server, SQLLite and Azure Table Storage.
Since the code based still not standardized, when it standarlized MySQL (Oracle) will work on the providers.
Another update for the question, EF7 is starting to support PostgreSQL, Please have a try on this below article.

I need a tool that I can create a phisical schema for my relational database. Something that I create tables, columns and relationships, and the tool generates sql to me.
PowerDesigner example
I've used PowerDesigner for many years in Windows and it has worked good to me. Now I need some similar to use in Arch Linux with gnome. Any suggestion?
oh.. my database is PostgreSQL and I look for something free.
[EDIT] I have tested some alternatives and no one serves me well. SQL Power Architect is discontinued and don't work properly. DBVisualizer is limited in free version. DataModeler don't generate sql how I expect.
I can recommend DbVisualizer. If you are limited by the free version you can start a free trial of the Pro version. On their Postgres page they seem to have what you need. DbVisualizer - PostgreSQL Client
We are currently using Oracle 10G database for the backend support of our application. We need to migrate the entire Oracle database schema into MySQL database, including all existing tables, views, procedures, triggers and sequences etc.
Can anyone kindly help me to guide the steps of migration, without hampering any schema definitions, keys and constraints etc.??
Also I came to know that MySQL does not support 'sequences'. In that case how can we convert the sequences which are present in Oracle database?
Please don't just mention any tool name, because I found few tools online but those are really lengthy and cumbersome processes to follow. Kindly mention step-wise, so that it's understandable easily.
I used Sql Developer IDE earlier, but it supports the reverse way migration, that is, from MySql to Oracle, not the one I need. Hence, I could not use it.
There is an Oracle Doc ID 1477151.1 for that case.
Though you asked to not mention any tool name, in that document Oracle advises to use MySQL Migration Wizard and provide some script examples for manual migration in case if automatisaton won't work.
Check those out. I hope that'll help
UPD: Again, I'm aware of you asking not to mention any tool, but here's another excerpt from that doc where even Oracle clearly says you have to use a third-party tool
Migration of Stored Procedures, Functions, Packages, Triggers, Views, Sequences must be performed using third party tools and needs manual effort. This document highlights method to perform data migration.
There are a host of third party tools, some of which are open source. For example:

I have been trying to experiment Devforce code-first with MySql. But am not able to find any resources explaining how to do it. Even am not able to find whether DevForce code-first supports MySql or not. (EF supports). Please help!
Thanks,
Kannan
DevForce is generally ignorant about the underlying database provider, and doesn't have any special requirements to work with MySQL. If you follow DevForce documentation for working with Code First, along with MySQL documentation for working with EF, you should be on the right track. If you're using a paid version of DevForce, contact support directly to get more information if you run into problems.
I know rukilo is an UI framework for Dart language but I wonder if it supports to use Mysql? And if it is, how to connect mysql with Dart? Thank you
We are developing Rikulo ORM to simplify the database access (but it is not opened yet). The first version will be built on top of WebSQL (SQLite) and IndexedDB. We do have a plan to bridge it to the backend server such as MySQL. Of course, there are some security and performance challenges to deal with.
I'm just starting to look into using LINQ for my database (and XML, and data object!) needs, but need to decide on which database to go with. I've been reading Pro LINQ, and it says that currently, LINQ in .NET 3.5 only supports SQL Server. I have done some googling, and have found references to using LINQ with MySQL and PostgreSQL (my other two DB options), but they are refer to DLinq, which I understand to be the predecessor of LINQ to DB.
I've read interesting and informative comparisons of the three databases here and here, but am still torn. I do not have any in-depth database experience, so it's important to be able to get the software installed and configured easily, or at least be easy to figure out how to compile a list of steps to configure it. I definitely want to have transactional support as well. But most importantly -- I want to use LINQ.
I'd like to hear what everyone here is using, whether it's SQL Server because LINQ supports it natively, or the other two with some additional component for LINQ support that I haven't yet found.
We use devart's dotConnect provider for Linq-to-Oracle and have been very pleased. They try and make the functionality match Linq-to-SQL as close as possible, which seems to be what you're looking for.
They have providers for:
Oracle
MySQL
PostgreSQL
SQLite
SQL Server
From a cost perspective, it's an excellent deal I'd say, just pay for developer seats, no server licensing.
