Database Software

Database Software
Database software is a program that controls the structure of database and access to the data. In other words, a database is any electronically stored collection of data in a computer system.

These computer based are organized according to their common elements so that data can be retrieved easily.

A database management system is a software that controls and manipulate the structure of a database.

Principal features of database software are as follows:

- Data base creation. Users can create a database by creating files (or tables). Each table has several fields. A field is a string of one or more characters. A field can have the attribute of text, data number, even object. After the format of a table is created users can input records into database. A record is collection of related fields. An example is a person’s name, address and phone number.

- File or report selection and display. After a database (consisting of several files) is created, users can manipulate this database by issuing queries. The function of a query is to screen all records by defined criteria.

- Database update. Users can deleted, add, or change record in a data file.

- Database calculation and formatting. Some database management system contains built in mathematical formulas. This feature can be used, for example, to find the average number of a selected group, as to find the average age of all customers who live in California.

The Future of Intranet and Extranet

The Future of Intranet and Extranet
Research and consulting project with many companies show not only their success with intranets, but that intranets and extranets will become even more pervasive in the business future.

One recurring theme for the future of intranets and extranets is the need to move beyond information publishing applications into enterprise information portal-enabled applications.

For example companies are planning more inquiry processing and transaction processing applications that tie the internet, intranets and extranets to mainframe and other legacy systems and databases.

Though such applications are more costly and difficult to develop, many companies are forging ahead.

These intranet using companies are in the process of web-enabling operational and managerial support applications, including online transaction processing, database integration and executive information and decision support.

For example, a sales inventory application might accept an order at a company’s World Wide Web site and then trigger on intranet search engine to search an internal inventory database for the product’s stock status.

Then a picking list and shipping notice would be prepared at the company’s warehouse intranet site.

Finally an e-mail’s message and invoice would be generated and sent via extranet to he customer’s own enterprise information portal.
