"loading data" means
copying data from one electronic file or database into another. Data loading implies converting from one format into another; for example, from one type of production database into a decision support database from a different vendor.
If you are not able to access database files, its means that your access database file is corrupted or damaged due to this reason your access file is inaccessible. To repair corrupt access database file, you can use compact and repair features. If this method is fail, then try access database recovery software. I have used access database recovery software many times and got 100% recovery back.

It is difficult to ensure atomicity in file processing system than database oriented system.
In file system, for example, transferring $20 from Person1 to Person2 account and between that process something went wrong there is no guarantee that the transfer was successful or not. While in a database system a guarantee of atomicity prevents updates to the database occurring only partially.
Hi
I guess when you say database thats what you mean and not schema . the terms of database and schema are different from one db to another .
Usually you don't create database from vb or other language, although i guess you can do that .
follow the commnds in the folowing link you just have to embed them in your vb code .
Microsoft access is a database application that is part of Microsoft Office. It lets you edit .MDB database files. Installing Access also installs the drivers that allow other applications which use the MS Access database format to also open their databases as well.
Not sure what your question means. If you want more information please ask me before rating the solution.
Generally database updates either require a commit to have the database perform the appropriate checking and actually flag the rows as part of the database. That Commit can occur in two ways -- some databases can be setup with an auto commit or auto rollback when the database is disconnected. The first means the programmer needs to do nothing. The second means if the programmer does not commit the updates are backed out of the database. To commit is generally considered bad because if there are any data errors partial transactions and logically inconsistent contents can exist in a database. For example entering an order for merchandise requires a single header row to identify the customer and multiple items rows to indicate what was ordered. If the third item record added to an order had an error and the application did not rollback and the database auto committed and incomplete order with only two items would be saved in the database. Traditionally databases with an automatic action at shutdown are set to rollback to assure such partial information is not saved. Even with auto rollback good programs detect errors and rollback themselves and allow users to continue.
The net result of the above is the probability that if the inserts actually occurred as you believe the there was a missing commit to confirm their addition to the database. and an automated rollback kept them from being completely added to the database. Another alternative is that the insert was not error checked in the program code and it failed meaning despite the program counter claiming rows were inserted in fact they were not.
