I was hoping someone could point me in the right direction. I have moved from a mysql db to mongodb. Is there any tools available to run against the two databases to ensure that the data is consistent.
Ive asked Google but ive been coming up empty. The other option i was considering was to write a script and take random samples from the db's and compare the results.
I doubt there is anything for this. The only way that I can see would be to write some script that compares the two data sources. But I do have to point out that if you just merely moved tables to collections, you will run into problems. The data schema that MongoDB likes for optimal performance is in no means going to be similar to what you'd use in a relational database such as MySQL.

I have to make a database for 250 students which will have around 100-200 columns. Now its not possible to install MYSQL or anything like that on the server.All we can get is a shared folder on the server. The client side can have anything installed. There will be around 5-10 clients who will add,edit or delete the records. I though about SQLite as an option. Is there any security issues with it???
I need a database to be accessed by a 5 to 10 clients. We do not have a full server per se but rather a shared folder on a server. We therefore cannot install any server-side software, only client-side.
I would use SQLite. You could also use MS Access but consider that problems with old MS Access databases are common in companies where Access where used on the late nineties.
Have a look at the following questions here

I have a large MySQL set of commands in a file (script) and I need to execute it on a Microsoft SQL Server 2008. I know there are few differences in both languages, despite the fact the base SQL is the same.
Is there any way how to convert a MySQL script to one that is executable on SQL Server? Or is there any migration app that can easily take the whole MySQL server and replicate everything on SQL Server 2008?
Thanks for any advice.
I tried Full Convert Enterprise with quite big success. Fast, easy and it did my job. Give it a try it may help you

I have a postgresql dump file and wants to convert it to MySQL. I google it and found pg2mysql which it converted successfully. However, I get errors when importing it to mysql. Looks like the formats are not compatible or wrong.
Any one can recommend?
Thanks.

The best solution for a migration would be a conversion tool like ESF data migration toolkit or openDBcopy that is open source.
According to your pastebin, the problem is with bigserial, as this is not a MySQL datatype. Some Googling came across this site which describes what bigserial is in Postgres context and other RDBMS datatype equivalents.
Looks like there are 3rd party libraries which will convert the data from Postgres to whichever RDMBS you choose, an example is easyfrom.net, if this doesn't fit your needs, just google around, as you are not the first person to need this functionality.

I just built an application with many complicated SQL queries - now I want to index them. Is there a good MySQL tool that lets me know what should be indexed?
I've heard about the Slow Query Log, but is there anything else that monitors my queries and tells me what needs to be indexed?
MySQL Query Analyzer helps you improve application performance by monitoring query performance and accurately pinpointing SQL code that is causing a slow down. With the new MySQL Connector Plug-ins, you can optimize performance applications more efficiently by communicating directly with the Query Analyzer.
