Introduction to Distributed Database System Names and Binding PPT Presentation:
Distributed system increases the efficiency and ease of software. Software’s and hardware have all things used in them for development have particular name. Naming this are user name, machine name, files names, device name, variables in the programs are named, network services used are named.
Name helps us to identify what we want. We need names for services, nodes, paths, objects within services. To name an object naming convection’s are being followed. To name a variable in a language a naming convention is being followed such as a variable name must start with a capital letter. Naming a object depends on some factors.
Uniqueness of the names is most important factor as duplication may lead to some conflicts.
b.) Naming Convention
Every naming convention system determines it own syntax for naming. Let us consider following naming system used.
UNIX Naming System
Unix Naming system parses components from left to right.
E.g. / Home/src/gps/gui.c
Internet Domain Names
Internet naming system is ordered from right to left and delimited by (.).
In LDAP naming convention the attribute value pairs are ordered from right to left and are delimited by (.). E.g. o=Rutgres,c=US
Always a particular name is associated to and objects. Naming convention is related to every context.
d.) Naming System
Naming system means common contexts are connected to each other along with some common properties.
e.) Name Space
Name space means set of names is the naming system.
Resolution is returning the underlying representation if name.
Address helps us to identify the location of a particular object with a specified name.
Route helps us indentify the path to a particular object with a specific name.
Binding binds or attaches an name with a object.
