This induce the use of redundant storage space on unneeded data or loss of data archives. The article presents the concept of flexible structures in relational databases. These structures enable the implementation of inheritance, creation of polymorphic tuples within one entity, and the creation of ...
Inheritance of interface is different from inheritance of implementation. Under public inheritance, derived classes always inherit base class interfaces. Pure virtual functions specify inheritance of interface only. Simple (impure) virtual functions specify inheritance of interface plus inheritance of a defaul...

All agents in SObjectizer are finite-state machines. Almost all functionality of hierarchical finite-states machines (HSM) are supported: child states and handlers inheritance, on_enter/on_exit handlers, state timeouts, deep- and shallow state history, except orthogonal states. Let's see how an...
Metaclass is a type used to create other types - it is an alternative way of doing subclassing / inheritance in Python, and a very powerful one too. If you understand metaclass you understand Python’s type system. If you are curious, see Primer on metacla...
A common use of object concatenation is "inheritance": data-center-generic= {cluster-size=6}data-center-east=${data-center-generic}{name="east"} A common use of array concatenation is to add to paths: path= [/bin]path=${path}[/usr/bin] ...
In C++, the string can be represented as an array of characters or using string class that is supported by C++. Each string or array element is terminated by a null character. Representing strings using a character array is directly taken from the ‘C’ language as there is no string type...

Inheritance of a dominant mutation in one of two breast/ ovarian cancer susceptibility genes (BRCA1 and BRCA2) is responsible for 2–7% of breast cancers and 10–15% of ovar- ian cancers.7–9 Implementation of prevention programs would reduce the burden of such inherited diseases, and in ...
