I update data in a access (2003) database. I immediatley want to access the database and at the moment, I have to put a Sleep command in. I have seen comments on ApplyUpdates for other databases but Access doesn't have one. Is there something else I can use?

ApplyUpdates  is part of the component TClientDataset;
What component are you using to access Access?  
dbExpress
TSQLQuery
TSQLTable
 ADO  
TADOTable
TADOQuery
BDE
TTable
TQuery

I am using TADOTable to update the data, and TADOQuery to subsequently read it.

Huh? That can't work really.
The answer to your original question is use Post method like;
MyTable1.Post;
commits the data to the database; but I think you have other issues;
since you can update ADOTable without first reading it;
And if your querying with ADOQuery why not update it?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I use a ADOTable.Post to commit the data to the database on one form.

On another form I try to read data, automatically, using a ADOQuery. The trouble is that when reading the data in the ADOQuery, it seems that the ADOTable.Post event hasn't written it to the database. If I put a Sleep(5000) between the ADOTable.Post and the read in using the ADOQuery, it works. But I have the problem that Sleep(5000) works on my machine but I have to use longer on other machines. I wondered if there was any other way?

It's really a design problem not a Delphi problem.
Are these separate applications you're calling 'Forms"?

If not, put the ADO data objects in a DataModule; so they can share an ADOConnection
Or put the ADOConnection on a common unit.
Or you could use a ClientDataset object and local data provider in a DataModule
