Remote Batch Invocation for SQL Databases

William R. Cook, Ben Wiedermann
2011 International Workshop/Symposium on Database Programming Languages  
In this paper we show how batch services provide a simple and powerful interface to relational databases, with support for arbitrary nested queries and bulk updates.  ...  Batch services are a new approach to distributed computation in which clients send batches of operations for execution on a server and receive hierarchical results sets in response.  ...  Acknowledgments We thank our collaborators, Eli Tilevich and Ali Ibrahim, for their help in making Batch2SQL possible.  ...

An Empirical Study of Local Database Usage in Android Applications

Yingjun Lyu, Jiaping Gui, Mian Wan, William G. J. Halfond
2017 2017 IEEE International Conference on Software Maintenance and Evolution (ICSME)  
Local databases have become an important component within mobile applications. Developers use local databases to provide mobile users with a responsive and secure service for data storage and access.  ...  However, using local databases comes with a cost.  ...  For example, both local and remote databases can be attacked using SQL injection (SQLI) attacks, if developers do not follow best practices for validating user input and interacting with the databases  ...

Integrating databases and workflow systems

Srinath Shankar, Ameet Kini, David J. DeWitt, Jeffrey Naughton
2005 SIGMOD record  
The definition of data products is in relational format, and invocation of programs and querying is done in SQL.  ...  We present a language for modeling workflows that is tightly integrated with SQL. Each scientific program in a workflow is associated with an active table or view.  ...  For example, consider the role of planning in a WFMS. In their analysis of batch workloads across remote compute clusters, Bent et al.  ...

A framework for scheduling parallel dbms user-defined programs on an attached high-performance computer

Michael A. Kochte, Ramesh Natarajan
2008 Proceedings of the 2008 conference on Computing frontiers - CF '08  
This framework is advantageous for many DBMS workloads in the following two aspects.  ...  Second, the interactive response time of the remaining applications on the database server platform is improved by the off-loading of long-running user-defined programs to the attached HPC platform.  ...  , or for multiple and related query invocations on the same target database table.  ...

Object Caching Design Framework for Improving Data Access Performance in Enterprise Applications

Nilayam KumarKamila, Renu Raghavan, Naveen Chalicheemala
2014 International Journal of Computer Applications  
But it becomes difficult to cache database results (dynamic data) when the database is manipulated by various external applications.  ...  In today's technological world, applications are designed to communicate across different interfaces and databases with high speed mode.  ...  Batch Job CacheLive Communication The batch job would run either on database local system or on the remote system where the application is running.  ...

2017 Proceedings of the 2017 ACM International Conference on Management of Data - SIGMOD '17  
Application programs that access data located remotely (such as in a database) often perform poorly due to multiple network round trips and transfer of unused data.  ...  These techniques optimize database application programs by identifying relational operations expressed in imperative code, and translating them into SQL.  ...  SIGMOD In this demonstration, we will showcase equivalent SQL translation for database applications written in Java that use JDBC or Hibernate to access the database.  ...

Integration of Oracle and Hadoop: Hybrid Databases Affordable at Scale

L Canali, Z Baranowski, P Kothuri
2017 Journal of Physics, Conference Series  
This work reports on the activities aimed at integrating Oracle and Hadoop technologies for the use cases of CERN database services and in particular on the development of solutions for offloading data  ...  The goal and interest of this investigation is to increase the scalability and optimize the cost/performance footprint for some of our largest Oracle databases.  ...  As previously mentioned, the interface used for running SQL remotely from Oracle makes use of Oracle database links.  ...

Real-Time UAV Trash Monitoring System

Yu-Hsien Liao, Jih-Gau Juang
2022 Applied Sciences  
The detection results were sent to a data streaming platform for data processing and analysis. The Kafka message queuing system and the Mongo database were used for data transmission and analysis.  ...  While a UAV is automatically controlled by an onboard computer, it can also be controlled through a remote station.  ...  The addition of a new column for the table in the SQL database is time-consuming. The advantage of SQL is that it is more suitable for complex queries.  ...

2016 Proceedings of the VLDB Endowment  
Moreover, the DSL-based approach has significant performance benefits as well, (1) by skipping (remote) API invocation overhead and (2) by applying high-level optimization from the compiler.  ...  In this paper, we present a new graph database system that integrates a robust graph storage with an efficient graph analytics engine.  ...  ACKNOWLEDGMENTS We thank Felix Kaser, Jinha Kim, Korbinian Schmid and Alexander Weld (Oracle Labs) for their work and contributions to PGX, the PGQL and Green-Marl language and for reviewing this paper  ...
