1. A method implemented in a computer infrastructure comprising a combination of hardware and software, the method comprising: monitoring available space within string fields having a predefined length within one or more tables having schema definitions; determining that space is available in the string fields having the predefined length within the one or more tables which have the schema definitions with the string fields having the predefined length based on the predefined length of the string fields within the one or more tables and used space of the string fields in the one or more tables; creating a tracker table of all of the available space within the string fields having the predefined length of the one or more tables; creating a virtual table; providing a percentage of the available space that can be mapped to the virtual table; and mapping the available space in the string fields to the virtual table for populating the virtual table with one or more records having a space which corresponds with the available space in the string fields, wherein the hardware comprises at least one processor.
