VTS enhances data integrity

VTS augments the tableBASE core product by providing the capability to share table data. Using tableBASE, every region loads tables into a local TSR. After augmenting the core product with VTS, all regions can access the same data from a shared TSR; a VTS-TSR.

Considering this scenario, if a single shared TSR is used, rather than the local TSRs, all regions will access a single copy of the data. Changes to the data made from one region are visible to all other regions immediately.

The problem of maintaining data integrity for multiple regions is now moot—this solution virtually guarantees data integrity across regions.
