What is Cyberinfrastructure?

cyberinfrastructure integrate hardware form computing, data and network, sensors, observatories and experimental facilities and software and middleware services and tools interdisciplinary terms, develop algorithms, sys os, and apps to exploit the full power of cyberinfrastructure to create, disseminate and preserve scientific data, information and knowledge

Privacy & Security in brife.

The term "privacy" denotes a socially defined ability of an individual (or organization) to determine whether, when, and to whom personal (or organizational) information is to be released.

The term "security" describes techniques that control who may use or modify the computer or the information contained in it.

The Protection of Information in Computer Systems

Some Terms In Computer Security

Access

The ability to make use of information stored in a computer system. Used frequently as a verb, to the horror of grammarians.

Access control list

A list of principals that are authorized to have access to some object.

Authenticate

To verify the identity of a person (or other agent external to the protection system) making a request.

Authorize

To grant a principal access to certain information.

Capability

In a computer system, an unforgeable ticket, which when presented can be taken as incontestable proof that the presenter is authorized to have access to the object named in the ticket.

Certify

To check the accuracy, correctness, and completeness of a security or protection mechanism.

Complete isolation

A protection system that separates principals into compartments between which no flow of information or control is possible.

Confinement

Allowing a borrowed program to have access to data, while ensuring that the program cannot release the information.

Descriptor

A protected value which is (or leads to) the physical address of some protected object.

Discretionary

(In contrast with nondiscretionary.) Controls on access to an object that may be changed by the creator of the object.

Domain

The set of objects that currently may be directly accessed by a principal.

Encipherment

The (usually) reversible scrambling of data according to a secret transformation key, so as to make it safe for transmission or storage in a physically unprotected environment.

Grant

To authorize (q. v.).

Hierarchical control

Referring to ability to change authorization, a scheme in which the record of each authorization is controlled by another authorization, resulting in a hierarchical tree of authorizations.

List-oriented

Used to describe a protection system in which each protected object has a list of authorized principals.

Password

A secret character string used to authenticate the claimed identity of an individual.

Permission

A particular form of allowed access, e.g., permission to READ as contrasted with permission to WRITE.

Prescript

A rule that must be followed before access to an object is permitted, thereby introducing an opportunity for human judgment about the need for access, so that abuse of the access is discouraged.

Principal

The entity in a computer system to which authorizations are granted; thus the unit of accountability in a computer system.

Privacy

The ability of an individual (or organization) to decide whether, when, and to whom personal (or organizational) information is released.

Propagation

When a principal, having been authorized access to some object, in turn authorizes access to another principal.

Protected object

A data structure whose existence is known, but whose internal organization is not accessible, except by invoking the protected subsystem (q.v.) that manages it.

Protected subsystem

A collection of procedures and data objects that is encapsulated in a domain of its own so that the internal structure of a data object is accessible only to the procedures of the protected subsystem and the procedures may be called only at designated domain entry points.

Protection

1) Security (q.v.).
2) Used more narrowly to denote mechanisms and techniques that control the access of executing programs to stored information.

Protection group

A principal that may be used by several different individuals.

Revoke

To take away previously authorized access from some principal.

Security

With respect to information processing systems, used to denote mechanisms and techniques that control who may use or modify the computer or the information stored in it.

Self control

Referring to ability to change authorization, a scheme in which each authorization contains within it the specification of which principals may change it.

Ticket-oriented

Used to describe a protection system in which each principal maintains a list of unforgeable bit patterns, called tickets, one for each object the principal is authorized to have access.

User

Used imprecisely to refer to the individual who is accountable for some identifiable set of activities in a computer system.

مقدمة دورة تحليل وتصميم وبناء أنظمة قواعد البيانات باستخدام SQL Server

بسم الله الرحمن الرحيم

تحليل وتصميم وبناء أنظمة قواعد البيانات باستخدام

2012 SQL Server

كنت قد القيت موخرا دورة حول تصميم وبناء انظمة قواعد البيانات باستخدام اس كيول سيرفر. فكرة الدورة تكون على مرحلتين كل مرحلة عدة دروس. كخطوة اولى الابتداء مع المبرمج من تحليل ثم تصميم ثم بناء نظام قاعدة البيانات والخطوة الثاني هي دورة اخرى مستقلة خاصة ببناء البرامج (ساتكلم عنها لاحقا). ان شاء الله ساقوم برفع دروس هذه الدورة بالتسلسل.

نظرة عامة على منهج الدورة:

·         Database Fundamentals  & Introduction To SQL Server

·         Working With SQL Server Management Studio

·         GUI VS CODE Programming (Creating Database & Tables & ……. )

·         Data Definition Language  (DDL).

·         Data Manipulation Language  (DML).

·         Data Control Language (DCL).

·         Transact-SQL Language in Details with examples (Views , Constraints , Scripts, Transaction, Stored Procedure, Functions, Template, Triggers, Programmability)

·         SQL Server Services (Reporting, Reporting  Services, Backup & Restore DB ……..)

·         Database Relationships & Normalization

·         Systems Analyses

·         Analyses

·         Design

·         Execute

·         Test

·         Client – Server Database

سيتم نشر دروس الدورة على قناتي في اليوتيوب:
