Towards a Realistic Model of Indices in Object Bases [chapter]

Boris Novikov
1996 Workshops in Computing  
A comparison of several indexing techniques for complex object in object-oriented database systems is presented, based on assumption of non-uniform distribution of attribute values.  ...  The cost estimations show that conventional ordered indices, especially nested indices with object skeletons, can provide better performance than signature files.  ...  The Object and Query Model In an object-oriented database scheme, real-world entities are represented by only one modelling concept: the object.  ...

Identifying New Directions in Database Performance Tuning

Derek Colley, Clare Stanier
2017 Procedia Computer Science  
However, this has resulted in generally poor query performance for SQL developed by object applications and an irregular fit with cost-based optimisation algorithms, and leads to questions about the need  ...  Proposals for further work include exploring concepts such as dynamic schema redefinition; query analysis and optimisation modelling driven by machine learning; and augmentation or replacement of the cost-based  ...  filters, and consequently an overall increase in query execution cost.  ...

An evaluation of vertical class partitioning for query processing in object-oriented databases

Chi-wai Fung, K. Karlapalem, Qing Li
2002 IEEE Transactions on Knowledge and Data Engineering  
In this paper, we develop a comprehensive analytical cost model for processing of queries on vertically partitioned OODB classes.  ...  The complexity of object-oriented database models due to subclass hierarchy and class composition hierarchy complicates the definition and representation of vertical partitioning of the classes, which  ...  In order to validate the analytical cost model, we have implemented a test object-oriented database schema with vertical partitioning functionality, using NeoAccess Object-Oriented Database System.  ...

Integrated Document-based Electronic Health Records Persistence Framework

Aya Gamal, Sherif Barakat, Amira Rezk
2021 International Journal of Advanced Computer Science and Applications  
The performance of the most popular two document-based NoSQL back-ends, Couchbase Server and MongoDB, is compared according to the size of the database and query execution time.  ...  By utilizing its analytics services and multi-dimensional scaling architecture, Couchbase Server multi-node cluster outperforms the response times of MongoDB for both simple and complex healthcare data  ...  Furthermore, this modeling approach brings additional storage costs. It could be considered as an optimal response scenario with only one user submitting a single query at a time.  ...

Decision Guidance Analytics Language (DGAL) - Toward Reusable Knowledge Base Centric Modeling

Alexander Brodsky, Juan Luo
2015 Proceedings of the 17th International Conference on Enterprise Information Systems  
DGAL allows the creation of modular, reusable and composable models that are stored in the analytical knowledge base independently of the tasks and tools that use them.  ...  Based on these unified models, DGAL supports declarative queries of (1) data manipulation and computation, (2) what-if prediction analysis, (3) deterministic and stochastic decision optimization, and (  ...  of an indexable object.  ...

Solutions for improving data extraction from virtual data warehouses

Adela BARA
2010 Database Systems Journal  
Some of the techniques that can be applied to reduce the cost of execution for improving query performance in BI systems will be presented in this paper.  ...  In this case there are several techniques that can be applied to reduce queries' execution time and to improve the performance of the BI analyses and reports.  ...  Our recommendation is that the ETL process should be implemented separately from the object oriented implementation in order to assure the independency of the MD model.  ...
