DESCRIPTION:In this talk\, I will present our ongoing research about evalu
 ating policies to update- or reconcile master/slave replicas.\n\nMaster/sl
 ave replication is a situation in which the same data is correctly represe
 nted by a master replica and possibly erroneously represented by a slave r
 eplica. Typically\, the slave replica is used for several business operati
 ons while the master replica is not. For example\, in inventory management
 \, the actual stock in the warehouse is the master copy and the stock regi
 stered in the information system is the slave copy. Even though the actual
  stock (master) is correct by definition\, it is the stock registered in t
 he information system (slave) that is used for business operations.\n\nWhe
 n organisations possess master/slave replicas\, they should make sure that
  both replicas are in sync by following and implementing update- or reconc
 iliation policies. If master/slave replicas are not in sync\, inconsistenc
 ies in the slave replica could have a major impact on business operations.
 \n\nNaturally\, before update- or reconciliation policies are actually imp
 lemented\, their effectiveness should be evaluated using\, for example\, s
 imulation. An important component of simulation is a simulation model.\n\n
 However\, to the best of our knowledge\, a general model to simulate updat
 e- or reconciliation policies is lacking from the literature.\n\nTherefore
 \, the aim of this research is to create such a simulation model and to de
 monstrate its applicability and utility by (1) making sure that it can sim
 ulate every aspect of update- and reconciliation policies\, and (2) by app
 lying it to simulate several candidate policies to reconcile master/slave 
 replicas at YH Global and KBC Group NV.
