The flash memory becomes a very popular storage device. Recently, it has replaced the traditional hard disc due to its shock - resistance and low power consumption. However, the flash memory architecture has some limitations related to the data management. Data cannot be updated in-place. That is why the flash translation layer (FTL) must be used. Nowadays, the flash memory seems to be the mature enough storage technology to work with databases. Among many database models, the column oriented databases have attracted the attention. This approach indicates the fact that data from the columns are packed together in the memory blocks. In this paper, we propose the Column Flash Translation Layer (CFTL) as an effective tool to store the data of the column oriented database in blocks of the flash memory.
