When NoSQL database systems are used in an agile software development setting, data
model changes occur frequently and thus, data is routinely stored in different versions. The
management of versioned data leads to an overhead potentially impeding the software
development. Several data migration strategies exist that handle legacy data differently
during data accesses, each of which can be characterized by certain advantages and
disadvantages. Depending on the requirements for the software application, we evaluate …

When NoSQL database systems are used in an agile software development setting, data
model changes occur frequently and thus, data is routinely stored in different versions. This
leads to an overhead affecting the software development and in particular, the management
of data accesses. In this context, different data migration strategies exist, which are
characterized by certain advantages and disadvantages. Using exactly that strategy whose
characteristics match the according migration scenario, depends on the query workload, the …
