Parallel Genetic Algorithms with Schema Migration
Proceedings 26th Annual International Computer Software and Applications, 2003 Genetic algorithms (GAs) are efficient non-gradient stochastic search methods. Parallel GAs are proposed to overcome the deficiencies of sequential GAs, such as low speed and aptness to locally converge. However the tremendous communication cost incurred offsets the advantages of parallel GAs.

NoSQL schema evolution and big data migration at scale
2016 IEEE International Conference on Big Data (Big Data), 2016 This paper explores scalable implementation strategies for carrying out lazy schema evolution in NoSQL data stores. For decades, schema evolution has been an evergreen in database research. Yet new challenges arise in the context of cloud-hosted data backends: With all database reads and writes charged by the provider, migrating the entire data ...

Advanced Features, Schema Migration
, 2013 Advanced features involve both persistence and data structures. Schema migration deals with changes of classes and their relations when storing data to disk. Extensible property allows one to add class members without changing the class declaration. We also discuss multi-user access to persistent data, ASLR and storing objects in flash memories and ...

A Schema for Indirect International Migration
International Migration Review, 1976 The earth is a closed system for human migration. Within the system all terrestrial areas of the world have been claimed by political states. Except for boundary disputes the universal exclusiveness of these territorial rights means that mankind is divided into political spaces so that one may not migrate to another territory without the receiving ...

Document-Oriented Data Schema for Relational Database Migration to NoSQL
2017 International Conference on Big Data Innovations and Applications (Innovate-Data), 2017 Big data has become a crucial issue and one of the most important technologies in the modern world. The management of a semi-structured data format for big data is an important concern that must be addressed. Most relational database management systems fail to handle the scalability and flexibility of big data. NoSQL, which is a new concept in database

Enabling Migration of Enterprise Applications in SaaS via Progressive Schema Evolution
, 2011 Update of applications in SaaS is expected to be a continuous efforts and cannot be done overnight or over the weekend. In such migration efforts, users are trained and shifted from one existed version to another new version successively. There is a long period of time when both versions of applications co-exist.

SQL-to-NoSQL Schema Denormalization and Migration: A Study on Content Management Systems
2015 IEEE International Conference on Systems, Man, and Cybernetics, 2015 Content management systems (CMSs) are able to let people, who have no technical skill to manage websites, rapidly create, edit, organize and publish online contents. For example, CMSs are often used to establish e-commerce online shops, community portals, personal blogs, or organization websites. Thus, CMSs play the role of collecting data and then can

Towards Self-Adapting Data Migration in the Context of Schema Evolution in NoSQL Databases
2020 IEEE 36th International Conference on Data Engineering Workshops (ICDEW), 2020 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.

Schema migration into a web-based framework for generating virtual museums and laboratories
2012 18th International Conference on Virtual Systems and Multimedia, 2012 This article describes ongoing work and further enhancements of the Replicave2 framework, which supports museum designers creating virtual museum exhibitions by reusing 3D models and dynamically generated content. It focuses primarily on the conversion of the individual software packages included in the toolbox ViMEDEAS (Virtual Museum Exhibition ...
