Example of New operator overloading in c++ const int maxnames = 5; class Names { char name[25]; static char Names::pool[]; static short int Names::inuse[maxnames]; public: Names(char* s = 0) { if (s) strncpy(name, s, sizeof(name)); } void* operator new[](size_t) throw(std::bad_alloc); void operator delete[](void*) throw(); void display() const { std::cout << name << std::endl; } }; // Simple memory pool to handle fixed number of Names. char Names::pool[maxnames * sizeof(Names)]; short int Names::inuse[maxnames]; // Overloaded new[] operator for the Names class. void* Names::operator new[](size_t size) throw(std::bad_alloc) { int elements = size / sizeof(Names); // Find the first empty element (if any). int p = -1; int i = 0; while ((i < maxnames) && (p == -1)) { if (!inuse[i]) p = i; ++i; } // Not enough room. if ((p == -1) || ((maxnames - p) < elements)) throw std::ba

Create Missing index using SQL Activity Monitor to process improvement If you want to improve performance of application then keep view on activity monitor in SQL and go to long executed query line then you can see from recent expensive query window screen . You can see the average duration of query execution. To get Missing Index details from Activity Monitor Screen in SQL to get more performance you can do following steps. /* Missing Index Details from ExecutionPlan1.sqlplan The Query Processor estimates that implementing the following index could improve the query cost by 93.6536%. */ /* USE [DB_TEST] GO CREATE NONCLUSTERED INDEX [<Name of Missing Index, sysname,>] ON [dbo].[GENERALJOURNALACCOUNTENTRY] ([CREATEDTRANSACTIONID]) GO */ Once you get index you can create index by directly executing query or you can create index manually. You can create index in query execution process time is very high.

Intranet and Extra net An Intranet is a private network (LAN) that uses the TCP/IP protocol suite. However, access to the network is limited only to the users inside the organization. The network uses application programs defined for the global Internet such as HTTP, and may have web servers, print servers, file servers etc. Extra net Private network that uses the Internet protocol and the public telecommunication system Shares part of a business's information with suppliers, vendors, partners, customers or other businesses. Viewed as part of a company's intranet that is extended to users outside the company. Artificial Neural Networks ARTIFICIAL NEURAL NETWORKS •Neural Networks can supplement the enormous potential of traditional computers with the ability to make sensible decisions and to learn by experience. •Neural Computation is done by a dense mesh of computing nodes and connections. They operate collectively and simultaneously on data inputs.

Structured query language The common commands and methods used in it are grouped into the following categories: Data Definition Language (DDL), Data Manipulation Language (DML), Data Control Language (DCL), Logical Connectors, Comparison operators, Aggregate functions, Joins, Sub query, Relational operators, Where clause etc. Data definition language covers SQL commands that create and destroy database tables. Data manipulation language covers SQL commands that create, change or destroy the information in a database table or the structure of the table. Data control language covers protection to the database such as granting access to the tables. Comparison operators cover those operators that allow for comparison between two items. Aggregate function deals with those standard SQL functions that allow programmers to narrow the search of a database. Joins category covers those items that allow information from two or more tables to be related. SQL Query Processing

Limitations of computer 1. No Feelings: Computers are not living. Hence, can’t make judgment of its own. Its instructions are based on information given to it in form of program. 2. It is Dumb: Computer posses no intelligence of it’s own. It’s I.Q. is zero. Computer can’t take it’s own decision in this regard. Definition of  Internet Internet is a worldwide network that provides an infrastructure to connect universities, government offices, companies, students, scientists, researchers and private individuals. A machine to be on the Internet means it runs TCP/IP protocol stack, has an IP address, and has the ability to send IP packets to all the other machines on the Internet. A private individual having a personal computer can call up an Internet service provider using a modem, be assigned a temporary IP address, and send IP packets to other Internet hosts.  An Internet consists of a set of connected networks that act as an integrated whole. The Internet provides universal
