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 softwar...

Fourth Generation Of Techniques in computer enginnering

 

Fourth Generation Of Techniques:-

Software developers to represent the desired result in a manner that leads to automatic generation of code to create those result. Obesely a data structure with relevant information must exist & be readily accessible by the 4th GT. To transform the 4GT implementation into a product, the developer must conduct proof testing, developing, meaningful documentation & perform all the other solution integration activities that are required in other software engineering.

In addition the 4GT developed software must be built in a manner that unable maintance to be perform.

Advantage:-

  • Simplify the programming process.
  • Use natural language that impose no rigid grammatical rules.   
  • Use non procedural language that users and programmers to specify the result they want, while the computer determine the sequence of introduction that will accomplish those results.

Disadvantage:-

  • Less flexible than other languages.
  • Programs written in fourth generation language are generally for less efficiency during program execution that program in high level language.

E-R model (Entity-Relationship model) in DBMS, Attributes

Image
 E-R Model (Entity-Relationship Model) :- It a  high level conceptual data model.  It allows us to describe the data involved in a real world inter price , in terms of objects & there relationship. It is validly used to developed an initial design of data base it provides a set of useful concepts that make it convenient for a developer. It describes data as a collection of entities relationship & attributes. Entities:- An entities is an object of consult used to represent the things in the real word. Eg:- Car, Table, etc. An entity need not be a physical entity it can also represent a concept in real words. Eg:- Project, Loan, etc. Entity Set:- A collection of similar kind of entities is called an entity set all entity type -> In college  database students, faculty, Course & Department are consort of check. The collection of all the students similarly collection of all course from an entity set course. Entity Identifier key attributes:- An entity type ...

Software testing, Software testing principals

Image
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:- Testing is a process which shows the presence of defect in the application. 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. 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. Testing is context development . It approac...

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 s...
