Software Quality Assurance in software engineering

Image
Software Quality Assurance (SQA):-  SQA is a set of activity assuring quality in software engineering process. Altimetry result in quality in software products. It include a following activities:- Process definition & implementation Auditing  Training  SQA is a process that insure hat developed software needs & compiles with defined or standardized quality specification. SQA is an on going process with in the SDLC that routinely checks the developed software to insure its needs desired quality measured. SQA helps to insure the development of high quality software. SQA practices are implementation in most type of software development regardless of underline software development model are being used. In a border sense SQA incorporate an implement software testing methodology to test software. SQA process test for quality in each phase of development until the software is completed. SQA genially works on one or more industries standards that helps in building software quality guid

Software testing, Software testing principals

Software testing:- 

It is a program intended to find errors. It is a process to evaluate the functionality of a software application with an intent to find weather the developed software meet the specified required or not & to product is defect free in order to produce the quality product.

Software testing principals:-

  1. Testing is a process which shows the presence of defect in the application.
  2. Exhaustive testing is impossible:-There is less possibility of testing with combinations of input, data, test & cinereous & recondition as they will take more time to test the process. Therefore the testing team can use some important testing criteria instead of doing exhausting testing.
  3. Testing activities will be conducted in the software or system development life cycle to find the defects as soon as possible. If errors are found in an initial stage of the development life cycle then it will be easier & cheaper to fixed the errors.
  4. Testing is context development . It approach depends on context of software development, different types of s/w need to perform different type of testing.
  5. To be most effective testing should be conducted by an independent third party.
  6. Testing should begin in small & progress toward testing in the large. 
  7. Some test cases are not repeated because once error encountered will not repeat with the same test case, its called Pesticide paradox.

Software development life cycle ,SDLC in software engineering

Image
SDLC (Software Development Life Cycle):- The system development life cycle also referred as to the application of development of life cycle is a done use in system engineering of software engineering. Phases of SDLC:- Gathering and analysis  Design Implementation of coding Testing Deployment  Maintenance Gathering and Analysis:- This is the first level of software development life cycle in this stage at the first all the information or gathered once then after analysis of information is taken. After gathering information the analysis is taking because to know what kind of software we have to developed by analyzing we come to know about software knowledge. Design:- After completing  the first step which was of gathering information an than analyzing them. Now we come for designing is the very much important role in SDLC. In this point we design a good quality of software. Implementation:- It is also most important point of SDLC. After designing the codes of software there comes implemen

Types of attributes in DBMS, derived, single valued, simple, multivalued, stored, composite

Image
 Types of Attributes:- Simple Attribute:-  The attributes that cannot be further divided in to smaller part an represents the basic meaning is called a simple attributes. Eg:- Age attributes of person entity represent a simple attribute. Composite Attribute:-  Attribute that can be further divided into smaller unit & each individual unit contains a specific meaning. Eg:- Name attribute of an employ can be sub divided. Multivalued Attribute:-  Attribute that have more than one values for a particular entity is called a multivalued attributes. Eg:- Phone no. for a person entity is a multivalued entity. Stored Attributes:-  Attribute that are directly stored attribute. Eg:- Date of joining attributes of employ entity.  Single valued attribute:-  Attribute having a single value for a particular entity. Eg:- Age is an single valued attribute of a student entity. Derived Attribute:-  Attributes are not stored directly but  can be derived from stored attributes are called derived attribut
