Database design involves three phases: conceptual design, logical design, and physical design. The conceptual design focuses on data requirements and results. The logical design describes the structure of the database. The physical design describes the implementation including programs, tables, and catalogs. Conceptual models represent data at a high level of abstraction while logical models can be processed by computers. Entity-relationship diagrams are commonly used for conceptual modeling and show entities, relationships, attributes, and other aspects.
Cloud computing is basically storing and accessing data and sharing resources over the internet rather than having local servers or personal device to handle applications.
Here we are trying to describe the UML diagrams. Those are Use-Case diagram, Activity Diagram, Sequence Diagram, Er Diagram, Class Diagram, Data-Flow Diagram. We describe the details figure of those diagrams.
What's LINQ, its advantages, its Operators and examples on some of them, Methods of Writing it.
LINQ to Objects and Collections and Data Source Transformation.
The objective is to explain how a software design may be represented as a set of interacting objects that manage their own state and operations and to introduce various models that describe an object-oriented design.

In software engineering, an entity–relationship model (ER model) is a data model for describing the data or information aspects of a business domain or its process requirements
Purchasing is the formal process of buying goods and services. The purchasing process can vary from one organization to another, but there are some common key elements.
The process usually starts with a demand or requirements this could be for a physical part (inventory) or a service. A requisition is generated, which details the requirements (in some cases providing a requirements speciation) which actions the procurement department. A request for proposal (RFP) or request for quotation (RFQ) is then raised. Suppliers send their quotations in response to the RFQ, and a review is undertaken where the best offer (typically based on price, availability and quality) is given the purchase order.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This slide is special for master students (MIBS & MIFB) in UUM. Also useful for readers who are interested in the topic of contemporary Islamic banking.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. Phases of Database Design
Data
Requirements
Conceptual design begins with the
Specification of requirements
and results
collection of requirements and results
Conceptual
needed from the database (ER Diag.)
Design
Logical schema is a description of the
Conceptual Schema structure of the database (Relational,
Logical Network, etc.)
Design
Physical schema is a description of
Logical Schema

3. Models
A data model is a collection of objects that
can be used to represent a set of data and
operations to manipulate the data
Conceptual models are tools for representing
reality at a very high-level of abstraction
Logical models are data descriptions that can
be processed by computers
3
4. Conceptual model:
Entity-Relationship Diagrams
Entities represent classes of real-world
objects. Person, Students, Projects, Courses
are entities of a University database
Relationships represent interactions
between two or more entities
N 1
Lives_In
Person City
Is_Born_In
N 1 4
5. Example:
Every employee works in at least one
project
Every project has employees working on it.
EMPLOYEE
N N PROJECT
SSN
WORKS_ON Name
Name
Code
Salary
5
6. Higher-Order Relationships
A relationship may involve more than two
entities
Course Meets Classroom
Day

7. Recursive relationships
Relationships could be mapped from one
entity to itself

Employee Manages

8. Attributes
Attributes represent elementary properties of the
entities or relationships. The stored data will be
kept as values of the attributes
Lives_In
N 1
CITY
PERSON Moving_Date
Name
Ssn
Country
Name Birth_Date
Profession Elevation
Population
Is_Born_In
N 1 8
9. Generalizations
• An entity could be seen from many different viewpoints
• Each viewpoint defines a set of roles in a generalization
• Example below uses SEX to classify the object “Person”
PERSON
Ssn
Name
Address
MAN FEMALE
Draft_Status Maiden_Name
9
10. Generalizations
A classification could be disjoint or
overlapping
An entity could have more than one
classification PERSON
Ssn
Name
Address
SEX JOB
Full_Time Part_Time
MAN FEMALE
Annual_Salary Hour_Rate
Draft_Status Maiden_Name

11. Example: Department Store 1/2
A department store operates in several
cities
In a city there is one headquarter
coordinating the local operations
A city may have several stores
Stores hold any amount of items
Customers place their orders for any
number of items to a given store
GOAL: Optimize shopping in each city 11

25. Job-Shop Accounting System 1/4
The system is used by a company that
manufactures special-purpose assemblies
for customers
To manufacture assemblies the company
creates a sequence of processes (steps)
Each process is supervised by a department
Assume there are three type of processes:
PAINT, FIT, CUT
25
26. Job-Shop Accounting System 2/4
During manufacturing an assembly could
pass through any sequence of processes, in
any order; it may pass through the same
process more than once
A unique Job# is given to any new
assembly.
Costs and started-terminated dates must be
recorded
26
27. Job-Shop Accounting System 3/4
Anaccounting system is used to keep track
expenditure for each:
DEPT,
PROCESS,
ASSEMBLY
Asa job proceeds, cost transactions can be
recorded against it.
