SQl DB Size definition

I am new to SQL, using SQL Developer 2014.

I created a SQL database by importing tables from an existing Access DB.  Now I'm poking around to see what I can learn.  I clicked on the 'Files' group in the Database properties viewer.

In the 'Database' group there is and 'Size' entry with a value of 39853.50 MB
Directly underneath that entry is 'Space Available' with a value of .078MB.

Does that mean I am almost out of space?  One reason for going to SQL from our old Access DB was to be able to store much more data.

I will eventually need to store a lot more data in this SQL DB, probably up to 10 times what I have now.

Where is the size of the DB, or space allocated to the DB set in SQL?  In other DB's I've used a primary space was allocated with rollover size increments if the data outgrew the original definition.

In general how is the disk space allocation handled and managed in SQL?

No it doesn't mean that you're running out of space.  That's the default DB size set during installation on your machine.

"Microsoft SQL Server 2008 Express edition has a database size limit to 4GB. Microsoft SQL Server 2008 R2 Express edition has a database size limit to 10GB. Microsoft SQL Server 2012 Express edition has a database size limit to 10GB. Microsoft SQL Server 2014 Express edition has a database size limit to 10GB."

The "space available" is out of the size already allocated from disk to that specific db.

If that db needs more space in the future, and you have enabled "Autogrowth", SQL will dynamically add more disk space to the db whenever it needs it, up to the max total size allowed (which defaults to "unlimited" for data files).  Be sure to specify "Autogrowth" as a fixed amount, such as 50MB, rather than 10% or some other %.  SQL performs better with a fixed amount and it's less risky.

Also, unless you have stringent security requirements, be sure to enable Instant FIle Initialization so that SQL doesn't have to pre-format data files.

Is SQL Server 2014 Developer the same as 2014 Express Edition?  I thought the Developer edition di not have a size limitation.

Is there any way, or for that matter need to, change the allocation size from 4GB to something larger?

No you are not out of space, SQL server automatically expand the data file whenever require.

Just make sure filegrowth is not set to restricted. It should be automatic and enough disk space should be available on disk.

@In general how is the disk space allocation handled and managed in SQL?

Here is very clear info:

@Where is the size of the DB, or space allocated to the DB set in SQL?

Current database size is 39853.50 MB and actual data size is SIZE- Available Space =actual.

On the same page (database property) , check the options given at left hand side, currently you are looking in General options, now click on FILES and check.

Sorry Scott I didn't see your answer before I responded.

Where do I set the 'Autogrowth' Property you mention?

Right click on database > Property> Files
here you can see autogrowth settings and change it accordingly like 50MB or 100MB..
