What is EAV? – Rahul Raikar
According to Rahul Raikar an Entity-Attribute-Value design normally involves a solitary table with three columns, these columns most often contain data referring to; the entity, an attribute, and a value for that attribute.
The Entity
The entity is a foreign key into an “Objects” table that records common information about every “object” (thing) in the database – at the minimum, a preferred name and brief description, as well as the category/class of entity to which it belongs. Every record (object) in this table is assigned a machine-generated Object ID.
The major benefit to a central objects table is that, by having a supporting table of object synonyms and keywords, one can provide a standard Google-like search mechanism across the entire system where the user can find information about any object of interest without having to first specify the category that it belongs to. (This is important in bioscience systems where a keyword like “acetylcholine” could refer either to the molecule itself, which is a neurotransmitter, or the biological receptor to which it binds.)
The Value
Coercing all values into strings, as in the EAV data example above, results in a simple, but non-scalable, structure: constant data type inter-conversions are required if one wants to do anything with the values, and an index on the value column of an EAV table is essentially useless. Also, it is not convenient to store large binary data, such as images, in Base64 encoded form in the same table as small integers or strings. Therefore larger systems use separate EAV tables for each data type (including binary large objects), with the metadata for a given attribute identifying the EAV table in which its data will be stored. This approach is actually quite efficient because the modest amount of attribute metadata for a given class or form that a user chooses to work with can be cached readily in memory. However, it requires moving of data from one table to another if an attribute’s data type is changed. (This does not happen often, but mistakes can be made in metadata definition just as in database schema design.)
The Attribute
In the EAV table itself, this is just an Attribute ID, a foreign key into an Attribute Definitions table, as stated above. However, there are usually multiple meta data tables that contain attribute-related information, and these are discussed shortly.
Entity-Attribute-Value model (EAV), also known as object-attribute-value model that is used in circumstances where the number of attributes (properties, parameters) that can be used to describe a thing (an “entity” or “object”) is potentially very vast.

Rahul Raikar Working On RIA (Rich Internet Applications)
Rich Internet applications (RIA) are web applications that have the features and functionality of traditional desktop applications . RIAs typically transfer the processing necessary for the user interface to the web client but keep the bulk of the data (i.e., maintaining the state of the program, the data, etc.) back on the application server .
RIAs typically:
- run in a web browser , or do not require software installation
- run locally in a secure environment called a sandbox
Rahul Raikar have tremendous experience with AJAX, Flex and with effective use of Open source Javascript toolkits available – We leverage on the existing tried and tested frameworks to effectively get the job done in time effective fashion.
Some of the JavaScript frameworks that we have competencies in are Mootools, JQuery, Prototype, Script.Aculo.Us, MochiKit, Rialto, Dojo Toolkit, Spry framework, Cean Ajax framework. Apart from this – we prefer the Open Source tool – Open Laszlo – which is a terrific tool to deliver RIA content to the web!

Below is a list of some of our works in RIA:-
- Graph based dashboard
A very elite graph based dashboard which works on XML – especially for middle level management to view pictorial representation of the sales figures. The chart on the left shows total revenue across all regions on a monthly places. When you click a data point in this chart, application updates the chart in the upper-right panel; that chart provides a breakdown of the contributions from each region for the given month. If you select a region in the breakdown of contributions, the application updates the chart in the lower-right panel, which shows that individual region’s revenue compared to the average for the given time period. Fully customizable to your needs!
