...will not affect the accessibility of data. • Ad hoc capability of query implementation: This model provides a simple method to implement and manipulate data. Purpose of the entity – relationship model The entity – relationship model is a conceptual level model that facilitates database design. From the vantage point of acme global the ER model will provide great assistance in visual representations. They will be able to understand the required data of their clients. The ER model will also increase all productivity with the integration of relational database model. Overall your client’s solution and file design will be implemented in a safe and simple model. Essential components of an ER Model • Entity: Object that exists and that can be distinguished from other objects. • Attributes: The properties related to a particular entity are known as attributes. • Relationship: The term defines how two or more entities are related to each other.

In the WHERE clause you can use operators such as LIKE, AND, OR, EQUAL, BETWEEN and IN. 2. What is the purpose of the Where clause when using SELECT? The purpose of this clause is to be able to list any conditions that are to be applied to the data retrieved. 3. What are data types and why are they important? A data type is a classification identifying one of various types of data, they are important because assigning data types gives meaning to collections of information 4. Provide an example of the GROUP by clause, when would you use this clause? SELECT Salesperson, SUM(Revenue) AS ‘Total’, MIN(Revenue) AS ‘Smallest’, MAX(Revenue) AS ‘Largest’, AVG(Revenue) AS ‘Average’, COUNT(Revenue) AS ‘Number’ FROM Orders GROUP BY Salesperson You use this clause when you need to see the information in a certain order 5. What is an aggregate function (provide 4)? How are they used? An aggregate function is a function where the values of multiple rows are grouped together as input on certain criteria to form a single value of more significant meaning or measurement AVG() - Returns the average value (average) COUNT() - Returns the number of rows (count) FIRST() - Returns the first value LAST() - Returns the last value 6.

...done separately prior to using the database. 2. Summarize in your own words the purpose of an E-R model specific to ACME Global Consulting. The E-R model can provide ACME Global with a specific, but open-ended design that is tailored to the company’s needs. This also allows us to sketch the design of a database informally and incorporate changes in order to avoid problems later on. The E-R model allows for growth beyond its ideas at inception. It lays the groundwork for later database relational designs. 3. List and describe essential components of the model such as entities, attributes, keys, relationships, roles, and dependencies specific to ACME Global Consulting. Entity: real-world object or thing with an independent existence and which is distinguishable from other objects. Examples are a person, car, customer, product, gene, book etc. Attributes: an entity is represented by a set of attributes (its descriptive properties), e.g., name, age, salary, price etc. Attribute values that describe each entity become a major part of the data eventually stored in a database. A key is a set of attributes for one entity set such that no two entities in this set agree on all the attributes of the...

... Term Paper Name: MANILA M V Roll No: CS08M028 Title: ThreeDimensional Password for More Secure Authentication Goal The goal is to design a multi factor authentication scheme that combines the the various authentication scheme into a single 3D virtual environment which results in a larger password space. The design of 3D virtual environment, the selection of object inside the environment, and the object type reflect the resulted password space. User have freedom to select whether the 3D password will be solely recall, recognition, or token based, or combination of two schemes or more. Brief Description of the System The proposed system is a multi factor authentication scheme. It can combine all existing authentication schemes into a single 3D virtual environment. This 3D virtual environment contains several objects or items with which the user can interact. The user is presented with this 3D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions toward the objects inside the 3D environment constructs the user’s 3D password. The 3D password can combine most existing authentication schemes such as textual passwords, graphical passwords, and various types of biometrics into a 3D virtual environment. The choice of what authentication schemes will be part of the user's 3D password reflects the user's preferences and requirements. A user...

...Case Study 1- Jenson Shoes The story begins with an African-American man named Lyndon Brooks, an employee at Jensen Shoes. Recent trends have identified a shortcoming in the company’s casual wear department. Brooks is therefore reassigned under the leadership of Jane Kravitz, much to his dismay. Several strategic objectives are formed to handle this shortcoming. Of these, two of the strategic objectives were assigned to Brooks, the Latino and African American markets. He was given a four month period to complete both objectives. According to a report pertaining to Brooks’ thoughts and impressions, he felt as if both the time allotted and the quality of manpower assigned to these two tasks were unreasonably lacking. Therefore the completion of both strategic objectives within the given timeframe to Brooks was infeasible. After several heated discussions between Brooks and Kravitz, Jane agreed to reassign the African-American strategic objective leaving only the Latino vertical markets to Brooks. Identifying the problem: Brooks vs. Jensen Shoes An important aspect to remember is that this case may contain a slight bias due to the fact that it is represented through merely Brooks’ perspective. Lyndon Brooks, a well educated Sociology graduate, is assigned to work under Jane Kravitz, manager of casual wear at Jenson Shoes. We see from analyzing the given report that Brooks had expressed disdain from the beginning. Initially assigned as a “Product Promotions Manager,” Brooks had...

...HOME WORK # 4 REVIEW QUESTIONS 4.4 In the context of access control, what is the difference between a subject and object. A subject is an entity capable of accessing objects (eg. user, application, process). A subject is typically held accountable for the actions they have initiated, and an audit trail may be used to record the association of a subject with security relevant actions performed on an object by the subject. An object is resource to which access is controlled. An object is an entity used to contain information. Any user or application actually gains access to an object by means of a process that represents that user or application. The process takes on the attributes of the user, such as access rights. In general, object is an entity used to contain and or receive information. Examples include records, blocks, pages. Segments, files, portion of files, directories, directory trees, mail boxes, messages and programs. 4.9 List and briefly define the four types of entities in a base model RBAC system. *USER: An individual that has access to this computer system. Each individual has an associated user ID. *ROLE: A named job function within the organization that controls this computer system. *PERMISSION: An approval of a particular mode of access to one or more objects. *SESSION: A mapping between a user and an activated subset of the set of roles to which the user is assigned.
