Difference Between Flow Charts and Flow Graph - Flowchart Alterntative

What the difference between Flow charts and Flow Graph? why can't we utilize Flow charts for software testing?

A program's flow charts resembles a control flow graph but there are some differences which are provided below:

Difference: Flow Charts and Flow Graph

1. In flow graphs, we don't show the details of what is in a process block whereas in flow charts every part of the process block is drawn.
2. In flow charts, different types of nodes are represented by different symbols, but we do not use different symbols in control flow graphs.
3. The flow graph focuses on control flow of the program whereas the flowchart focuses on process steps and due to this reason, flow charts are not used for testing.

What is Flow Charts 

Graphic representation or Symbolic representation of process shown in the figure below called Flow charts. So different symbols are used to denote process which contains a little description of the process. These symbols are linked together via arrows showing the flow of the process.

Alternative Names of Flow Charts

Unfortunately, there are lot of variations and common alternatives names of the flow charts. Those names includes.

  • Flow charts
  • Process flow charts
  • Process map
  • Process chart
  • Process model 
  • Process flow diagram
  • Flow diagram. 

These naming convention are annoying because teachers teach or call them as flow chart only. Those are the little names found on Breeze Tree. What people search online is all those names.

Different calling conventions in different area of field. Like Process map which is another name for flow chart that assign attribute data. Input and Output to each process steps. But "Process map" is refers to flow charts that map the interrelationships between top level procedures in an ISO 9000 system.

Data Consistency and Inconsistency - What is Difference

  Data Consistency: Definition 1: Data consistency means that the changes made to the different occurrences of data should be controlled and managed in such a way that all the occurrences have the same value for any specific data item. Data inconsistency leads to a number of problems, including loss of information and incorrect results. In the database approach, it is controlled because data is shared and consistency is controlled and maintained. Data Consistency Definition 2: Data consistency meaning is the validity, accuracy and usability of related data. It ensures that each user observes a consistent(Same) view of the data, including changes made by the user’s own transactions and transactions of other users. Types of Data Consistency: Point in time consistency Transaction consistency Application consistency Data Inconsistncy: Data Inconsistency Definition: Data inconsistency meaning is that different versions of the same data appear in diffe

  Logical Relationship in Tables: Database tables have a major advantage to bridge them with some logical relationship so to filter the records. These relationship allowed us to access one table data using another table records(via columns or rows). In other words logical filtration is called cardinality DBMS. Read Also: Relational Model in DBMS Definitions of Cardinality in DBMS: Definition 1: A number that represents, one instance of first entity(table) is related to how many instances of the second entity, is known as cardinality in dbms. Definition 2: Cardinality is a relationship or join/bridge between rows of  1 table to the rows of another table. via some column (e.g. User Table column {user_id} in another table Posts to filter the posts by user_id). Types of Cardinality in DBMS: There are three types of Cardinality in DBMS. one-to-one one-to-many many-to-one many-to-many Read Also: Degree of Relationship in DBMS one-to-one

Relational Model in DBMS

  Relational Model (RM) represents the database as a collection of relationships. A relationship is nothing more than a table of values. Each row of the table represents a collection of related data values. These rows of the table denote a real-world entity or relationship. The table name and column names are useful for interpreting the meaning of the values in each row. Data are represented as a set of relationships. In the relational model, the data are stored as tables. However, the physical storage of data is independent of how data is organized logically. Some popular relational database management systems are: DB2 and Informix Dynamic Server – IBM Oracle and RDB – Oracle SQL Server and Access – Microsoft Concepts of relational model in DBMS Attribute: Each column in a table. Attributes are the properties that define a relationship. e.g. Student_Rollno, NAME, etc. Tables – In the Relational model the relationships are saved in table format. It is s
