Database tools and technologies affected the business processes and decision making by a great extent. The most important benefit of the database is to change unstructured information into structured information, and allow users to analysis the data stored into different tables with the help of queries. Before database, all the information used to stored into paper and other unstructured computer programs, due to which getting required information process was very slow. Due to database, all the

Relational Database Management Systems are probably the ones that we are most familiar with in 21st century computer science. Relational databases store

Relational data is when you can put data in a computer one time and it grows

* Transaction Processing Systems (TPS): It is a type of information system. TPSs collect, store, modify, and retrieve the transactions of an organization. A transaction is an event that generates or modifies data that is eventually stored in an information system. To be considered a transaction processing system the computer must pass the ACID test. The essence of a transaction program is that it manages data that must be left in a consistent state (Wikipedia.com).

CDRs are often referred to as transactional databases because they aid online transaction processing (OLTP). A transaction is nothing more than an entry, retrieval, or process on data. A physician entering a drug order for a patient, the nurse (or patient monitoring device) entering vital signs, the pharmacist retrieving data on patient allergies, the coder calling up the patient’s problem list, or the R-ADT system calculating the patient’s age from the

Database Processing: is the system of collecting, storing, and processing data for the purpose of gathering information, managing information, and creating new knowledge from the stored data. Database Management Systems: Data processing in business is most often done using Database Management Systems (DBMS). A DBMS is used to create, process, and maintain a database. Some common inputs and outputs of a DBMS include; tables and forms to input data, queries to retrieve data, and reports to output and present data. Enterprise Database Managements Systems: this is a database system that supports a multi-user environment. These are most often used in large businesses that require employees to input and process data using a variety of different applications. Common enterprise technologies

Capturing and gathering all data necessary to complete the processing of transactions is called data input.

Computer Information Systems (CIS) have forever altered the way in which organizations conduct business. No longer is commerce managed through clunky and expensive paper-based transactions. The advantage of this archaic process, though, was that it allowed corporations to store their documents in secure locations under tight lock & key. Today however, these cabinets have been replaced with database systems. Database systems are the modern version of filing cabinets, which house the vast data transacted by corporations.

Determining Databases and Data Communication is important because it allows me to manage data and query, store information, and has proven to be a essential component in day-today business.

System performance is one of the most critical issues faced by companies dealing with vast amounts of data. Companies use database systems and their applications to store, retrieve and handle this data.

The data that flows through this system should be highly structured and detailed, examples of data that may be processed include transactions made by customers and the organization itself, internal reports for staff, finance and other kinds of data such as complaints, incidents etc.

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

A database is a system that is specialized to manage data in a computer application system. Data has many forms, such as text, digital, symbols, graphics, images and sound. The database systems are integral components of current and future command, communication, control and intelligence information systems. (Lunt, 1992, p. 253)
