Odbcdirect is no longer supported re write anime

Lots of subjects are nuanced, this doesn't mean we need a separate site for them, this means we need to step up with providing guidance on how to write good questions for the subject, not a separate site. The issue with the OP wanting to establish Teamviewer sessions and not getting feedback is because the OP answers highly localized questions, and Stack Overflow isn't really suited for that.

The first version of Jet was developed inconsisting of three modules which could be used to manipulate a database. Microsoft Access and Visual Basic use or have used Jet as their underlying database engine. For larger database needs, Jet databases can be upgraded or, in Microsoft parlance, "up-sized" to Microsoft's flagship SQL Server database product.

Architecture Jet, being part of a relational database management system RDBMSallows the manipulation of relational databases. It offers a single interface that other software can use to access Microsoft databases and provides support for security, referential integritytransaction processingindexingrecord and page locking, and data replication.

In later versions, the engine has been extended to run SQL queries, store character data in Unicode format, create database views and allow bi-directional replication with Microsoft SQL Server. Locking Jet allows multiple users to access the database concurrently.

To prevent that data from being corrupted or invalidated when multiple users try to edit the same record or page of the database, Jet employs a locking policy.

Any single user can modify only those database records that is, items in the database to which the user has applied a lockwhich gives exclusive access to the record until the lock is released. In Jet versions before version 4, a page locking model is used, and in Jet 4, a record locking model is employed.

Data is stored in "records" of variable length that may take up less or more than one page. The page locking model works by locking the pages, instead of individual records, which though less resource-intensive also means that when a user locks one record, all other records on the same page are collaterally locked.

As a result, no other user can access the collaterally locked records, even though no user is accessing them and there is no need for them to be locked. In Jet 4, the record locking model eliminates collateral locks, so that every record that is not in use is available.

There are two mechanisms that Microsoft uses for locking: With pessimistic locking, the record or page is locked immediately when the lock is requested, while with optimistic locking, the locking is delayed until the edited record is saved.

Conflicts are less likely to occur with optimistic locking, since the record is locked only for a short period of time.

However, with optimistic locking one cannot be certain that the update will succeed because another user could lock the record first. With pessimistic locking, the update is guaranteed to succeed once the lock is obtained.

Other users must wait until the lock is released in order to make their changes. Lock conflicts, which either require the user to wait, or cause the request to fail usually after a timeout are more common with pessimistic locking.

Transaction processing Jet supports transaction processing for database systems that have this capability.

A transaction is a series of operations performed on a database that must be done together — this is known as atomicity and is one of the ACID Atomicity, Consistency, Isolation, and Durabilityconcepts considered to be the key transaction processing features of a database management system.DAO with ODBCDirect: Support has been dropped with Access DAO via JET: You're not serious, right?

Anyway, it's considered obsolete by Microsoft. ADO with the SQLOLEDB provider: Deprecated. ADO with the SQL Server Native OLEDB provider: Won't be supported after SQL Sever Worse however, and that's the issue here, is that ODBCDirect has been pulled from the newer versions of Access including and for both and bit Access.
