Object-oriented databases is more flexible and stores data as well as instructions to manipulate the data.

A system known as an object database uses object-oriented programming to represent data in the form of objects. Different from relational databases, which are table-oriented, are object-oriented databases.

The concept of object-oriented programming languages, which is currently popular, is the foundation of the object-oriented data model. Overloading, polymorphism, and inheritance Object-oriented programming fundamentals that have found use in data modelling include object-identity, encapsulation, and information hiding with methods to provide an interface to objects. The rich type system, which includes collection and structured types, is supported by the object-oriented data model as well.

In contrast to relational databases, which can only handle one type of data, object databases can handle multiple data types. Unlike conventional databases like hierarchical, network, or relational, object-oriented databases can handle a variety of data types, including text, numbers, images, voice, and video.

Also, Reusable code, realistic modelling, and increased dependability and flexibility are all provided by object-oriented databases.

A. Calculate the diffusion coefficient for magnesium in aluminum at 450°C.
SIZIF [17.4K]

Answer:

a) D = 4.88 * 10^(-14) m^2 / s

b)   <em>t </em>= 1.1 hr

Solution:

a) Magnesium in Aluminum diffusion:

D = Do * exp(-Qd / RT)

  =  (1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15)

  = 4.88 * 10^(-14) m^2 / s

D = 4.88 * 10^(-14) m^2 / s

b) The composition remains same at say the distance Xo:

(Cx - Co) / (Cs - Co) = Constant

Xo^2 / D_{550} * <em>t </em>= Xo^2 / D_{450} * 15

D_{550} * <em>t </em>= D_{450} * 15

(1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15) * <em>t</em>

(4.88 * 10^(-14) m^2 / s) * 15

by, solving for <em>t </em>we get:

 <em>t </em>= 1.1 hr

So, the time required is 1.1 hr.
