Database system vs file system-computer world

  Database system vs file system

 Data redundancy 

it means duplication of data for more than one place. Like a customer detail like name, account number, address are stored at more than one place. In file system redundancy of data increase which consume more space and more difficult to maintain. By using DBMS we can reduce data duplication and update the data.

 Insert and delete records 

In file system we cannot insert and delete any particular record from data. DBMS provides faculty of deletion and also we can easily insert new record or data.

 Difficult to search the data

 In file system if we want to search popular record for example record of that customer who's minimum balance is 75000 in saving account so it is difficult to retrieve those data. But by using DBMS there are searching options are easily available.

 Security problem

 In file system there is very less or no security DBMS provides high level security mechanism like password,security, bio metric devices.

 Data isolation

 In file system there is no standard format of data, so retrieving data is now difficult.

Concurrent access anomalies 

For speed and faster working, we need to accept more than one data concurrently but it is difficult to access in file system.

Single partition allocation, Multiple-partition allocation and Fixed Equal-size partitions in operating system-computer world

  Single partition allocation, Multiple-partition allocation and Fixed Equal-size partitions in operating system Single partition allocation In this scheme operating system is residing in law memory and user process are executing in higher memory. Advantages It is simple  It is easy to understand and use Disadvantages User job is limited to the size of available memory. It leads to poor Utilization of processor and memory. Multiple-partition allocation  It is the simplest method for allocating  memory is divided memory into several fixed size partitions. Fixed Equal-size partitions It divides the main memory Into equal number of fixed sized partitions, operating system occupies some fixed portion and remaining portion of main memory is available for user processes. Advantages It supports multi programming. A process whose size is less then or equal to the partitions size can be loaded into any available partition. Disadvantages If a program is big to fit in...

Aggregation and Functional dependency in DBMS-computer world

  Aggregation and  Functional dependency in  DBMS Aggregation  In aggregation the relation between two entities is treated as a single entity. In aggregation relationship with its corresponding entity is aggregated into higher level entity . It is the process of compiling information on object, there by obstructing a higher level. On limitation of the ER model is that it can not Express relationship among relationships. The aggregation represent a relationship between a whole object and its component in other word we can say that using aggregation we can express relationship main relationships.  For example center entity offer the course entity act as a single entity in the relationship which is in a relationship with another entity visitor. In the real world if a visitor visits a coaching center they will never inquiry about the course or just about the center instead he will ask the inquiry about both. Functional dependency  Functional dependency play an ...

Difference between HTML and DHTML-computer world

     Difference between HTML and DHTML  HTML is a markup language, while DHTML is a collection of Technology.  DHTML creates dynamic web page, whereas HTML create static web page.  DHTML allow including small animations and dynamic menus in web pages but HTML is not able to do so.   HTML used events, methods, properties to insulate dynamism in HTML pages.   HTML is used to describe the web page but DHTML is a collection of JavaScript and style sheet in an HTML page. HTML sites will be show upon client side Technologies, while  DHTML site will be fast enough upon client side Technologies as most of entries are checked on browser itself and not waste time rendering to server for mistake.  HTML creates a plain web page without any style and scripts called as HTML. Whereas,  DHTML creates a page with HTML, CSS,DOM And scripts called as DHTML.  HTML cannot any server side code but XHTML may contain server side code.  ...
