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...

Types of Computers:-
Super computer:-
Fastest calculating device can process the data in neno pico second. Use to create & analysis models and nuclear fusions & fission, producing action & reaction of millions of all atoms as they react. Helps in analyzing weather patterns & global worming & the depletion of earth ozone layer, can store very large amount of data.
Mainframe Computer:-
Higher connectivity, fastest through puts & large data processing capabilities, also support large capacity disk can connect over 256 terminal. Process large number of application library for helping to application developers have the capability of addressing large memory size as compare to mini computer.
Mini Computer:-
It also support multi user environment, use for resource sharing, memory size is large , support multiple terminal. Bit using high performance & high capability process. Provide to connect multiple printer.
Micro Computer:-
It is smallest least expensive, they have smallest memory, less power , physically smaller & permits fewer, peripheral to be attached. They are know as PC.
Micro Computer types:-
- Desktop
- Laptop
- Network computer
- Hand hold personal computer

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