With these  advantages, it is feasible that PCM could be the future of data storage as it has  the potential to replace both secondary storage and main memory.  In this thesis, we study the current status of PCM in the memory hierarchy,  its characteristics , advantages and challenges in implementing the technology.  Specifically, we study how the byte-writeable PCM can be used as a buffer for  flash SSD to improve its write efficiency. Then in the second part, we study how  traditional relational database management should be altered for a database  completely implemented in PCM. Specifically, we study this effect by choosing  hash-join algorithm. The experiments are carried out in a simulated environment, by modifying  a DRAM to act as a PCM. We use postgreSQL database for relational database  experiment. The results show that PCM has many benefits in the current  memory hierarchy.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659145865\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659145865","offer_id":39434266738781,"sku":"9783659145865","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f420f419-104a-4528-b0e4-ee425815511b.jpg?v=1773381384","url":"https:\/\/shop.autorenwelt.de\/en\/products\/phase-change-memory-in-relational-database-von-suraj-pathak","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
