First hand information, such as eyewitness accounts, creative works, and scientific or reflective discovery.

15

What is secondary information?

A

Is the verification of or commentary about discoveries or events, and therefore you are reliant upon the ideas and observations of others, this includes newspaper articles, histories, etc.

20
Q

What is a file system?

A

A file is a collection of related information, in a file system data are stored in independent files each requiring its own data management programs.

21
Q

What are the problems with file system data management? (2)

A
  • Complexity leads to difficulty

* Security features are difficult to implement

22
Q

What is a database?

A

An organised collection of facts and information (Stairs & Reynolds, 2008), it could be through a computer and it aids creation of information and knowledge.

23
Q

What is a ‘Flat file database’?

A

Simple database whose records have no relationship to one another (i.e. no links) e.g. excel.

24
Q

What is a ‘relational database’?

A

Contains relations or links between tables within the database and minimises the incidence of redundant data through the use of ‘keys’. eg. Access

25
Q

What is the difference between a single user and multiple user database - give examples?

A

Single user are on a single computer, where as multiple can be used across computers. Access is single user, Oracle is a multi-user.

26
Q

What is a database system?

A

Logically related data stored in a single data repository rather than many separate and unrelated files. Database Management Systems store the data, the structure and the relationships.

27
Q

What are the five most important aspects of a Database Management System (DBMS)?

A
  • Data management
  • Query languages
  • User access
  • Integrated view of organisation’s operations
  • Reduction of inconsistent data
28
Q

What are the four types of data according to Stair & Reynolds (2008)?

A
  • Alphanumeric
  • Image
  • Audio
  • Video
29
Q

Information creation is a process that begins with what?

A
  • Observation and codification of data and statistics.
30
Q

The programs within the Database Management System provide functions that facilitate what?

A
  • Backup & recovery
  • Methods for accessing data in a computer system
  • Supporting database administration.
31
Q

What are databases comprised of?

A
  • Entities - things we want to collect & store
  • Attributes - descriptors of some aspect of the entity
  • Relationships - association among entities
32
Q

What is the Primary key?

A

It is a unique attribute, every instance must have one and there must be no duplicates.

33
Q

How is entity data stored? and what are the features?

A
  • Entity data is stored in a ‘table’ (also called a ‘relation’)
  • Attributes in the columns
  • Records in the rows
34
Q

What is ‘cardinality’?

A

It describes the relationship between entities, and can include one-to-many; one-to-one; and many-to-many.

35
Q

What is a ‘foreign key’?

A

An attribute which refers to a primary key of another entity eg. primary key represents a person, in the cars table, the foreign key is the primary key of the person. It links the person to the car.

36
Q

What are the characteristics of valuable information (11)?

  • Accurate
  • Complete
  • Economical to produce
  • Flexible

  • Secure
  • Simple
  • Timely
  • Verifiable
37
Q

What are the two fairness issues with use of data?

A
  • The right to know

* The ability to decide

38
Q

What are the two database storage options and two database usage options to consider when storing personal information?

A
  • Knowledge - should they know what data is stored?
  • Control - should they be able to update their data?
  • Notice - should they be informed if the data is to be used for another purpose?
  • Consent - should they have to consent to the use of the data in different ways?
39
Q

What is SQL and what is it used for?

A

Standard/Structured Query Language and it is used to create, transform and retrieve information from Relational Database Management Systems.

40
Q

What is the logical design view of a database?

A

It shows an abstract model of how the data should be structured and arranged to meet an organisations information needs. It identifiers the relationships and grouped items.

41
Q

What is the physical design view of a database?

A

It starts from the logical database design and fine tunes it for performance and cost (reduced response time, storage space etc)

42
Q

What is unique about the Relational model of Database Management System?

A

Data and relationships are represented as tables each of which has a number of columns with a unique name. There is no explicit links between the tables but they link by sharing a common entity.

43
Q

What are the advantages of the relational model?

A
  • Structural independence
  • Data independence
  • Easy to design and maintain
44
Q

What are the disadvantages of the relational model?

A
  • Requires substantial hardware and operating system overhead
  • Slower than other database systems
45
Q

What is a candidate key?

A

It is a unique identifier of a row but was not necessarily chosen to be the primary key

46
Q

What are two examples of primary key and candidate key?

A

Primary - Student ID, TFN

Candidate - Social Security Number, Email Address

47
Q

What is an ERD?

A

An Entity Relationship Diagram is a model that identifies the concepts or entities that exist in a system and the relationships between those entities.

48
Q

When defining relationships in an ERD, how are Optionality and Cardinality expressed and what do these mean?

A

They are expressed as symbols at the ends of the relationship lines and indicate Optionality (optional / mandatory relationship) and Cardinality (1:1, many:1, and many:many).

49
Q

What does an o in the relationship line indicate?

A

That the relationship is optional, if followed by a stroke on the line then it means that the relationship is a minimum of zero and a maximum of 1.

50
Q

What does two strokes on the line mean?

A

Minimum of 1 and maximum of two instances

51
Q

What does a stroke followed by a crows foot

A

Minimum of 1 and maximum of many instances.
