MonetDB
MonetDB is a high-performance applications in data mining, OLAP, GIS, XML Query, text and multimedia retrieval. MonetDB often achieves a significant speed improvement for SQL and XQuery over other open-source systems.
MonetDB achieves its goal by innovations at all layers of a DBMS, e.g. a storage model based on vertical fragmentation, a modern CPU-tuned query execution architecture, automatic and self-tuning indexes, run-time query optimization, and a modular software architecture.
Its major features include:
- High-performance database management system
- Multi-model system
- Column-store based database kernel
- Broad spectrum database system
- Extendable database system
- Database back-end is multi-threaded and guards a single physical database instance
- Operations are cache- and memory-aware with supreme performance
- Index selection, creation and maintenance is automatic
- Connectivity is provided through TCP/IP sockets and SSH on many platforms
- Could be Embedded
- Programming interfaces available in all major languages

N-orm - Java non-object relational mapping to ordered map databases (HBase and Redis)
What is n-ormn-orm offers a simple persistence layer for Java. Targeted stores are "no-sql" as the framework assumes a column-oriented like storage data model. The framework makes use of annotations and a very simple query language, simple enough to be very efficient, and too simple to let a model not to be efficient... ;-) Current stores are HBase and Redis, though new drivers should be simple to implement. Expectations on a data store are that it can handle maps automatically sorted according

jQGrid Integration Kit for Oracle PL/SQL and Application Express (Apex)IntroductionI started developing applications back in the good (?) old client/server days. I was fortunate enough to discover Delphi quite early. Even from the start, the lowly 16-bit Delphi version 1 had a kick-ass DBGrid control which allowed you to quickly and easily build data-centric applications. Just write a SQL statement in a TDataSet component, connect it to the grid, and voila! Instant multi-row display and editing

Caramel-plugin - A Rails plugin for quick-and-easy RedCloth support in your models.
Caramel: a RedCloth enabler for RailsCaramel is a Ruby on Rails plugin that facilitates conversion of Textile input to HTML via RedCloth. Problem:If you have a text field, say 'content', in your model and you intend to use that text field to contain the HTML for your web pages, then either the user of your web app must know HTML or else you'll have to convert the user's input from some other format like Textile. The latter solution is quite attractive, and on top of that there is a great Ruby ge
