A DB2 bind is a process that builds an access path to DB2 tables. 

Access specifiers in C++ determines the scope of the class members.

Public: If a class member is public, it can be used anywhere without the access restrictions.

Private: if a class member is private, it can be used only by the members and friends of class.

Protected: If a class member is protected, it can be used only by the members and friends of class and the members and friends of classes derived from class.

A DB2 utility used to collect statistics about the data values  in tables which can be used   by the optimizer to decide the access path. It also collects statistics used for space   management. These statistics are stored in DB2 catalog tables.

ARC is a compiler-level feature that simplifies the process of managing the lifetimes of Objective-C objects. Instead of you having to remember when to retain or release an object, ARC evaluates the lifetime requirements of your objects and automatically inserts the appropriate method calls at compile time.

In C++, void represents the absence of type, so void pointers are pointers that point to a value that has no type. The void pointers can point to any data type.

You can declare void pointer as follows:

void *p;

Direct method,

 Subtraction method,

 Modulo-Division method,

 Digit-Extraction method,

 Mid-Square method,

 Folding method,

Pseudo-random method

There are many answers here: Reduce image sizes, remove unnecessary widgets, HTTP compression, put CSS at the top and script references at the bottom or in external files, reduce lookups, minimize redirects, caching, etc.

REORG reorganizes data on physical storage to reclutser rows, positioning overflowed rows in their proper sequence, to reclaim space, to restore free space. It is used after heavy updates, inserts and delete activity and after segments of a segmented tablespace have become fragmented.
