I have been using MS IIS server and MS Sql client Management Studio at workplace on Windows system. My home system is a Ubuntu system and I like setup a database server and a client to interact with the database. So I want recommendations on the server software and client I can go for in Ubuntu
SQL client: With GUI, allowing queries, (auto complete/intellisence is advantageous)
SQL server: should support relational database.
I am expecting multiple answers and chose the one I like after trying them all.
