Operational Business Intelligence: Processing Mixed Workloads
Found in: IT Professional
By Michael Seibold,Dean Jacobs,Alfons Kemper
Issue Date:September 2013
pp. 16-21
Modern business applications have operational business intelligence features that require processing analytical queries and business transactions together at the same time and on the same data. This results in mixed workloads, which are a big challenge for...
Strict SLAs for Operational Business Intelligence
Found in: Cloud Computing, IEEE International Conference on
By Michael Seibold,Alfons Kemper,Dean Jacobs
Issue Date:July 2011
pp. 25-32
Today, SLAs for SaaS business applications usually lack stringent service level objectives and significant penalties. Moreover, Operational Business Intelligence features of modern business applications, like analytic dashboards, result in mixed workloads ...
Predicting in-memory database performance for automating cluster management tasks
Found in: Data Engineering, International Conference on
By Jan Schaffner,Benjamin Eckart,Dean Jacobs,Christian Schwarz,Hasso Plattner,Alexander Zeier
Issue Date:April 2011
pp. 1264-1275
In Software-as-a-Service, multiple tenants are typically consolidated into the same database instance to reduce costs. For analytics-as-a-service, in-memory column databases are especially suitable because they offer very short response times. This paper s...
Extensibility and Data Sharing in evolving multi-tenant databases
Found in: Data Engineering, International Conference on
By Stefan Aulbach,Michael Seibold,Dean Jacobs,Alfons Kemper
Issue Date:April 2011
pp. 99-110
Software-as-a-Service applications commonly consolidate multiple businesses into the same database to reduce costs. This practice makes it harder to implement several essential features of enterprise applications. The first is support for master data, whic...
Towards enterprise software as a service in the cloud
Found in: Data Engineering Workshops, 22nd International Conference on
By Jan Schaffner, Dean Jacobs, Benjamin Eckart, Jan Brunnert, Alexander Zeier
Issue Date:March 2010
pp. 52-59
For traditional data warehouses, mostly large and expensive server and storage systems are used. In particular, for small- and medium size companies, it is often too expensive to run or rent such systems. These companies might need analytical services only...
A comparison of flexible schemas for software as a service
Found in: Proceedings of the 35th SIGMOD international conference on Management of data (SIGMOD '09)
By Alfons Kemper, Dean Jacobs, Michael Seibold, Stefan Aulbach
Issue Date:June 2009
pp. 3-4
A multi-tenant database system for Software as a Service (SaaS) should offer schemas that are flexible in that they can be extended different versions of the application and dynamically modified while the system is on-line. This paper presents an experimen...
Multi-tenant databases for software as a service: schema-mapping techniques
Found in: Proceedings of the 2008 ACM SIGMOD international conference on Management of data (SIGMOD '08)
By Alfons Kemper, Dean Jacobs, Jan Rittinger, Stefan Aulbach, Torsten Grust
Issue Date:June 2008
pp. 13-14
In the implementation of hosted business services, multiple tenants are often consolidated into the same database to reduce total cost of ownership. Common practice is to map multiple single-tenant logical schemas in the application to one multi-tenant phy...

Found in: Proceedings of the 2005 ACM SIGMOD international conference on Management of data (SIGMOD '05)
By Anno Langen, Bill Gallagher, Dean Jacobs
Issue Date:June 2005
pp. 868-872
There is a class of data, including messages and business workflow state, for which conventional monolithic databases are less than ideal. Performance and scalability of Application Server systems can be dramatically increased by distributing such data acr...
Safety and translation of calculus queries with scalar functions
Found in: Proceedings of the twelfth ACM SIGACT-SIGMOD-SIGART symposium on Principles of database systems (PODS '93)
By Dean Jacobs, Martha Escobar-Molano, Richard Hull
Issue Date:May 1993
pp. 253-264
We consider infinite recursive (i.e., computable) relational data bases. Since the set of computable queries on such data bases is not closed under even simple relational operations, one must either make do with a very humble class of queries or considerab...

Found in: ACM Transactions on Database Systems (TODS)
By Dean Jacobs, Richard Hull, Shahram Ghandeharizadeh
Issue Date:March 1988
pp. 370-426
Traditional database systems provide a user with the ability to query and manipulate one database state, namely the current database state. However, in several emerging applications, the ability to analyze “what-if” scenarios in order to reason...
