“…In this work, extensive research was carried out in the state of the art of data fragmentation, obtaining the most related approaches, classifying them, and describing each one of them. It is observed that fragmentation methods proposed in [ 32 , 56 , 73 ] present simple cost models for their implementation. [ 32 , 56 ] carry out a dynamic vertical and horizontal fragmentation respectively.…”

“…Figure 4 shows a bar graph that relates the number of articles to the publisher; most of the articles are concentrated in the Springer publishing house. Springer’s articles primarily addressed vertical ([ 22 , 24 , 25 , 26 , 32 , 33 , 34 , 36 ]) and horizontal ([ 1 , 43 , 46 , 47 , 51 , 55 , 58 , 59 , 63 , 66 ]) fragmentation, 18 of 26 articles. Only one article considers both fragmentation and CBIR ([ 1 ]).…”

“…The vast majority of vertical fragmentation algorithms are static, that is, they optimize vertical fragmentation schemes using a workload, but if it undergoes changes, the schema will also suffer, resulting in long query response times. In [ 32 ], Rodríguez-Mazahua et al proposed a set of active rules to perform dynamic vertical fragmentation on multimedia databases. Active rules are implemented in DYMOND (DYnamic Multimedia ONline Distribution), which is a system based on active rules for dynamic vertical fragmentation of multimedia databases.…”

“…The proposed algorithm searches for the most suitable vertical partition scheme to later obtain the hybrid scheme taking into account the cost model described in the same work. To carry out the experiments, the same scenario was used as in [ 32 ]. As a result, the hybrid partition method for multimedia databases was obtained, which reduces access to irrelevant data, taking into account the size and selectivity of each attribute, and also presented a cost model for distributed multimedia databases.…”

Fragmentation is a design technique widely used in multimedia databases, because it produces substantial benefits in reducing response times, causing lower execution costs in each operation performed. Multimedia databases include data whose main characteristic is their large size, therefore, database administrators face a challenge of great importance, since they must contemplate the different qualities of non-trivial data. These databases over time undergo changes in their access patterns. Different fragmentation techniques presented in related studies show adequate workflows, however, some do not contemplate changes in access patterns. This paper aims to provide an in-depth review of the literature related to dynamic fragmentation of multimedia databases, to identify the main challenges, technologies employed, types of fragmentation used, and characteristics of the cost model. This review provides valuable information for database administrators by showing essential characteristics to perform proper fragmentation and to improve the performance of fragmentation schemes. The reduction of costs in fragmentation methods is one of the most desired main properties. To fulfill this objective, the works include cost models, covering different qualities. In this analysis, a set of characteristics used in the cost models of each work is presented to facilitate the creation of a new cost model including the most used qualities. In addition, different data sets or reference points used in the testing stage of each work analyzed are presented.
