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...

Data Base Management DBA

  


DATA BASE MANAGEMENT (DBA)

Centralized control of the database is achieved by a person or group of persons under the super version of a high level administration this person or group is refer to as the data base administration.

DBA is responsible for creating, modified & maintaining, its 3 level.

The DBA is the causation of the data & controls database structure. The DBA administrates the 3 level of database & in consultation with the overall user community setup the definition of conceptual level of the database

The DBA further specifies the user view of the various users:-

  • DBA is responsible for definition & implantation of the internal level including the storage structure & excess method to be used for the optimum performance of the DBMS.
  • DBA is responsible for granting  permission to the users of the database & store the profile of each user in the database. This profile describe the permissible act of a user on that question of the database accessible to the user.
  • The DBA is also responsible for defining producer recover the database from humans, natural or hardware cause with minimum loss of data.    

         D.B.M.S Facilities:-

Data Definition Language (DDL):-

Database management system provides a facilities DDL which can be used to define the conceptual schema of the database the definition also includes any constants that have to maintain.

Data Manipulation Language (DML):- 

The language use to manipulate data in the database is called DML.

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 ...

Structure of Database Management System (DBMS)

Image
   Structure of Data Base Management System:-          The measure components of DBMS described below:- Data Manager:-  It is the central software component of the DBMS. It is some times called database control system. Main function of the data manager is to convert operation in the user queries directly via the query processor or indirectly by an application program from the user logical view to a physical file system the data manager is also responsible for interfacing with the file system. The tasks of informing constraints to maintain the consistently and integrity of the data as well as its securely are also performed by data manager backup & recovery operations are  also performed by data manager. File Manager:- It is responsible for the structure of file & managing the file space it is also responsible for location the block containing the required record. Disk Manager:- The manager is a part of operating system of the host com...

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...
