SciServer builds upon and extends the Sky- education Server system of server-side tools that introduced the astronomical community to SQL (Structured computing Query Language) and has been serving the Sloan Digital Sky Survey catalog data to the public. SciS- databases erver uses a Docker/VM based architecture to provide interactive and batch mode server-side analysis server-side analytics with scripting languages like Python and R in various environments including Jupyter (notebooks), data science RStudio and command-line in addition to traditional SQL-based data analysis. Users have access to private file storage as well as personal SQL database space. A flexible resource access control system allows users to share their resources with collaborators, a feature that has also been very useful in classroom environments. All these services, wrapped in a layer of REST APIs, constitute a scalable collaborative data-driven science platform that is attractive to science disciplines beyond astronomy. -

A Relational Multi-Schema Data Model and Query Language for Full Support of Schema Versioning?
A Relational Multi-Schema Data Model and Query Language for Full Support of Schema Versioning? Fabio Grandi CSITE-CNR and DEIS, Alma Mater Studiorum – Universita` di Bologna Viale Risorgimento 2, 40136 Bologna, Italy, email: [email protected] Abstract. Schema versioning is a powerful tool not only to ensure reuse of data and continued support of legacy applications after schema changes, but also to add a new degree of freedom to database designers, application developers and final users. In fact, different schema versions actually allow one to represent, in full relief, different points of view over the modelled application reality. The key to such an improvement is the adop- tion of a multi-pool implementation solution, rather that the single-pool solution usually endorsed by other authors. In this paper, we show some of the application potentialities of the multi-pool approach in schema versioning through a concrete example, introduce a simple but comprehensive logical storage model for the mapping of a multi-schema database onto a standard relational database and use such a model to define and exem- plify a multi-schema query language, called MSQL, which allows one to exploit the full potentialities of schema versioning under the multi-pool approach. 1 Introduction However careful and accurate the initial design may have been, a database schema is likely to undergo changes and revisions after implementation. In order to avoid the loss of data after schema changes, schema evolution has been introduced to provide (partial) automatic recov- ery of the extant data by adapting them to the new schema. -

Chapter 2: Database System Concepts and Architecture Define
Chapter 2: Database System Concepts and Architecture define: data model - set of concepts that can be used to describe the structure of a database data types, relationships and constraints set of basic operations - retrievals and updates specify behavior - set of valid user-defined operations categories: high-level (conceptual data model) - provides concepts the way a user perceives data - entity - real world object or concept to be represented in db - attribute - some property of the entity - relationship - represents and interaction among entities representational (implementation data model) - hide some details of how data is stored, but can be implemented directly - record-based models like relational are representational low-level (physical data model) - provides details of how data is stored - record formats - record orderings - access path (for efficient search) schemas and instances: database schema - description of the data (meta-data) defined at design time each object in schema is a schema construct EX: look at TOY example - top notation represents schema schema constructs: cust ID; order #; etc. database state - the data in the database at any particular time - also called set of instances an instance of data is filled when database is populated/updated EX: cust name is a schema construct; George Grant is an instance of cust name difference between schema and state - at design time, schema is defined and state is the empty state - state changes each time data is inserted or updated, schema remains the same Three-schema architecture -

Customers who choose to deploy Cisco Unified Intelligence Center (Unified Intelligence Center) as their reporting platform must add the Informix database as a data source in Unified Intelligence Center. The schema is fully published so that customers can develop custom reports. Customers may not, however, extend the schema for their own purposes. The schema provides Unified CVP customers with the ability to: • Establish database connectivity with Unified Intelligence Center and to import and run the Unified CVP templates with Unified Intelligence Center. • Establish database connectivity with other commercial off-the-shelf reporting and analytics engines and then build custom reports against the Unified CVP database schema. Note Your support provider cannot assist you with custom reports or with commercial (non-Cisco) reporting products.
