The process involves defining personnel and departmental subsystems, dividing the system into component subsystems.

ANALYSIS OF GOALS AND PROBLEMS

creates a structured representation of the goals and problems of an enterprise and associates them with departments or organizational units and with the management

CRITICALITY RANKING

Both goals and problems should be given a criticality ranking.

EXECUTIVE INTERVIEWS

the heart of goal and problem analysis

CRITICAL SUCCESS FACTOR ANALYSIS

are particular components or action areas on which a company, team, or department must focus and effectively implement in order to achieve its strategic goals. When these success elements are executed well, the business will benefit and substantial value will be created

Process Modeling

Used to organize and document the flow of data through a business system

• Decomposition Diagram

A simple chart that breaks a system into levels: System, Function, and Activity (THE STRUCTURAL VIEW)

• Data Flow Diagram

also called a bubble chart or transformation graph. It shows the actual work or processing performed on data (THE OPERATIONAL VIEW)

RELATIONAL DATABASE

is a type of database that stores and provides access to data points that are related to one another.

• RELATION/TABLE

A relation is nothing but a table with rows and column.

• ATTRIBUTES/COLUMN

Attributes are the properties that define a relation.

• TUPLE/ROW/RECORD

Each row in the relation is known as tuple.

• DOMAIN

A domain is unique set of values permitted for an attribute in a table.

• DEGREE

The number of attributes in a relation.

• CARDINALITY

The number of tuples in a relation.

KEYS

is that data item which exclusively identifies a record.

• PRIMARY KEY

uniquely identifies each record in a table and must never be same for two records.

• CANDIDATE KEY

is an attribute or set of attributes that uniquely identifies a record.

• SUPER KEY

for an entity is a set of one or more attributes whose combined value uniquely identifies the entity in the entity set.

• COMPOSITE KEY

is a group of fields that are combined together, to uniquely identify a record.

• FOREIGN KEY

the column whose data values correspond to values of a key column in another

DATABASE NORMALIZATION

is the process of restructuring data or aligning, transforming, and organizing it to make it uniform, reduce redundancy, and improve consistency

INSERTION ANOMALIES

It occurs when it is not possible to insert data into a database because the required fields are missing or because the data is incomplete.

DELETION ANOMALIES

It occurs when deleting a record from a database and can result in the unintentional loss of data.

UPDATION ANOMALIES

occurs when data is inconsistently updated across a database, typically due to data redundancy.

• 1_1 (One-to-One)

One instance of Entity A links to only one instance of Entity B

• 1_N (One-to-Many)

One instance of Entity A links to multiple instances of Entity B.

• M_N (Many-to-Many)

Multiple instances of Entity A link to multiple instances of Entity B

IMPORTANCE OF INFORMATION STRATEGY IN CONSTRUCTION

• Better Decision Making • Improved Collaboration • Reduced Costs and Delays • Increased Safety • Long-Term Asset Management

TYPES OF CRITICAL SUCCESS FACTORS

• Industry Factors • Environmental Factors • Strategic Factors • Temporal Factors

ADVANTAGES OF IMPLEMENTING CRITICAL SUCCESS FACTORS

• Improved Performance Measurement • Better Resource Allocation and Prioritisation • Streamlined Performance Reporting • Boost in Employee Satisfaction • Higher Levels of Achievement

TYPES OF HEIRARCHY USED IN CASE TOOLS

• FUNCTIONALITY HEIRARCHY • COMPONENT HEIRARCHY • PROCESS HEIRARCHY

IMPORTANCE OF RELATIONSHIP FRAMEWORK

• Validate the Results • Link Results to Business Outcomes • Credibly Merchandise Impact • Set Smarter Objectives and Strategies • Midcourse Adjustments and Corrections • Adapt Over Time
