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.

Cloud computing – efficient way of handling high traffic websites

What is Cloud computing?

Cloud computing is getting extremely popular these days. Especially if you have a high traffic website / web based application and you don’t want to spend too much into hosting high end dedicated servers – cloud computing / cloud hosting is what you are looking for,.

Cloud computing is a general term for anything that involves delivering hosted services over the internet. Basically a cloud is a virtualization of resources that manages and maintains itself. Broadly classified under the three categories:

1. IaaS: Infrastructure as a service.
2. PasS: Platform as a service.
3. SaaS:Software as a service.

So how does a cloud hosting differentiate with other hosting? The most important difference  is that cloud computing is sold “on demand”. This also means that there is no binding on you to buy heavy duty hosting servers and be worried about how to manage, maintain and keep on paying for the extra resources where you don’t need any. This on demand service is typically sold by hour or minute and has no load on the customer to worry about the maintenance or paying for extra space or bandwidth. Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing.

Typically there are two types of clouds – Public and Private. A public cloud as the name says – sells services to anyone on the Internet where as a Private cloud is more like a proprietary network or a data center that caters to a limited number of people for hosting services.
