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

White Box Testing, Black Box Testing



Black Box Testing:-

It is a software testing method in which the initial structure design, implementation of the item being tested is not known to the tester. Black box testing mainly applicable to the higher level of testing acceptance testing, system testing. It generally independent software tester. 

Programming knowledge is not required. Implementation knowledge also not required.

White Box Testing:-

It is a software testing method in which the internal structured, designs, implementation of the item is being known to the tester. In white box testing tester knows about the internal structure & programming to. White box testing mainly applicable to lower level of testing such as unit testing & integration testing. 

The important part in this is at the starting phase of software development we can know about the error arises at the time of developing software. This testing is also known as open or glass box testing & also called structural testing.

Computer Added Software Engineering (CASE), features of Computer Added Software Engineering (CASE), Computer Added Software Engineering (CASE) tools in Software engineering

Image
  Computer Added Software Engineering (CASE) It describe a broadest of label, saving tools used in software development. These create a framework for managing project and intended to help the users stay organized & improve productivity. There was more interest in the concept of CASE tools years ago, but let so today as the tools have different function of and in reaction to software development needs. The concept of CASE also received a heavy dose of critics after its heavy days. Features of CASE:- CASE tool, which are some times called integrated-CASE or ICASE. Tools cover all aspects of the software development life cycle which includes the writing code, implementation & maintenance.  The tools help in every aspect of the development work- Managing  Modules  Error checking Version control Designing  Diagramming tool Prototyping and other aspect associated with software engineering  Compling & testing tool are also consider parts of CASE tool set. CASE Tools:-  It are used

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
