Say for e.g. I have 100 of tables in a database and I use SQL Server 2008 to generate the ERD diagram for me. How can I logically group the related tables so that at one glance user will only see the portion they want to see rather than the whole lot of tables in the database relationship?
You can create more than one diagram, showing the various areas of your database

When should one consider using a metamodel in place of an expensive analysis component? I haven't actually seen an example of an openMDAO project that uses metamodels yet, so I was wondering if they're recommended or whether it's still best to treat expensive analyses like normal ones.
Using a metamodel is a trade-off. You trade accuracy vs execution time so it is up to you in your context.

I have a file with 120k records and the key is the username. I want to delete records for some username.
Delete all records for username in "ABC","dd","EEE" etc.
I am using R language
You could also use this.
df1[!(df1$username %in% c("ABC","dd","EEE")),]
df1[!(df1$username %in% c("ABC","dd","EEE")),]
Let me know if its still not working.

I am using Plone 4.3 and I would like to connect to a MySQL database and display the results of a query in a webpage.
How can I do that?
Thanks in advance,
Andrew
Some years ago I developed an add on for doing exactly that thing:
https://pypi.python.org/pypi/redturtle.sqlcontents
It uses sqlalchemy.
You may want to include in your buildout MySQL-python.
Read the package documentation with attention: it stresses out some important remark about security.
