Facilitating SQL Query Composition and Analysis [article]

Zainab Zolaktaf, Mostafa Milani, Rachel Pottinger
2020 arXiv   pre-print
These results are encouraging and confirm that SQL query workloads and data-driven machine learning methods can be leveraged to facilitate query composition and analysis.  ...  Formulating efficient SQL queries requires several cycles of tuning and execution, particularly for inexperienced users.  ...  We introduce additional problems related to facilitating query composition and analysis, e.g., session classification.  ...

Synergistic graph and SQL analytics inside IBM Db2

Yuanyuan Tian, Wen Sun, Sui Jun Tong, En Liang Xu, Mir Hamid Pirahesh, Wei Zhao
2019 Proceedings of the VLDB Endowment  
Db2 Graph is an in-DBMS graph query approach. It is implemented as a layer inside an experimental IBM Db2™, and thus can support synergistic graph and SQL analytics efficiently.  ...  We use an example scenario on health insurance claim analysis to demonstrate how Db2 Graph is used to support synergistic graph and SQL analytics inside Db2. PVLDB Reference Format:  ...  In Db2 Graph, we add optimized strategies in the Traversal Strategy component to combine multiple steps into one composite step and to translate the composite step into an optimized SQL query.  ...

Business Rules For Data Warehouse

Rajeev Kaula
2009 Zenodo  
The star schema structure and the business rules are stored within a relational database. The approach is explained through a prototype in Oracle-s PL/SQL Server Pages.  ...  Business rules and data warehouse are concepts and technologies that impact a wide variety of organizational tasks.  ...  Essentially, each business rule is processed through a SQL query using dynamic SQL concepts. Once the query is executed, its results are further processed to validate the business rule.  ...

Enhancing ER Diagrams to View Data Transformations Computed with Queries

Carlos Ordonez, Ladjel Bellatreche
2019 International Workshop on Data Warehousing and OLAP  
The explanation is simple: a relational database has a collection of tables that are joined and aggregated with complex relational queries, and whose columns are transformed with complex SQL expressions  ...  More importantly, similar SQL queries tend to be written multiple times, creating problems in database evolution, disk space utilization and software maintenance.  ...  The first consideration is notation for queries. SQL has bag semantics and SQL queries tend to be verbose.  ...
