The Oracle relational database management system (RDBMS) provides an open, comprehensive, integrated approach to information management<br/>

A database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information.
The Oracle relational database management system (RDBMS) reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. This is accomplished while delivering high performance. At the same time, it prevents unauthorized access and provides efficient solutions for failure recovery.
<br/><br/>
Connecting to a Server<br/>
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhi5HKJJkSxiARGGX2J31hwelXQhOZc9mVKdLFOSAG93MSQiT0kxDE6syfaUxdmVKLNxdeQmObWni8lLr3R7SJbrVCmM7bIj_wNn5dxcIrNmZOn5dxkE5OGFSJ0hwo8EEK-ivOHBcqOBcja/s1600/oracle5.jpg" imageanchor="1" ><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhi5HKJJkSxiARGGX2J31hwelXQhOZc9mVKdLFOSAG93MSQiT0kxDE6syfaUxdmVKLNxdeQmObWni8lLr3R7SJbrVCmM7bIj_wNn5dxcIrNmZOn5dxkE5OGFSJ0hwo8EEK-ivOHBcqOBcja/s1600/oracle5.jpg" /></a><br/><br/>
A database user can connect to an Oracle server in one of three ways:<br/>
  . The user logs on to the operating system running the Oracle instance and starts an application or tool that accesses the database on that system. The communication pathway is established using the inter-process communication mechanisms available on the host operating system.<br/>
  . The user starts the application or tool on a local computer and connects over a network to the computer running the Oracle database. In this configuration (called client/server), network software is used to communicate between the user and the back-end server. <br/>
      - The client/server architecture database system has two parts: a front end (client) and a back end (server) connected through a network. Network software is used to communicate between the user and the Oracle server.<br/>
The client is a database application that initiates a request for an operation to be performed on the database server. It requests, processes, and presents data managed by the server. The client workstation can be optimized for its job. For example, the client might not need large disk capacity, or it might benefit from graphic capabilities. Often, the client runs on a different computer than the database server. Many clients can simultaneously run against one server.<br/><br/>
Oracle Database Server Architecture: Overview<br/><br/>
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIZ1KJHkoJSIbwiERUx633gfMd48y7dcXOhyphenhyphenH2u-BtqAq7HIbshekKTPXjI51C1gUnxhoi3Zp9YRvMCc5iB42FKTIOc1YkcJUeIy4GClbHrixMN42xsm5-r8U2lcaMlsEMW6nG3fHGRih_/s1600/1.jpg" imageanchor="1" ><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIZ1KJHkoJSIbwiERUx633gfMd48y7dcXOhyphenhyphenH2u-BtqAq7HIbshekKTPXjI51C1gUnxhoi3Zp9YRvMCc5iB42FKTIOc1YkcJUeIy4GClbHrixMN42xsm5-r8U2lcaMlsEMW6nG3fHGRih_/s1600/1.jpg" /></a><br/>
There are three major structures in Oracle Database server architecture: memory structures, process structures, and storage structures. A basic Oracle database system consists of an Oracle database and a database instance.
The database consists of both physical structures and logical structures. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting access to logical storage structures.
The instance consists of memory structures and background processes associated with that instance. Every time an instance is started, a shared memory area called the System Global Area (SGA) is allocated and the background processes are started. Processes are jobs that work in the memory of computers. A process is defined as a “thread of control” or a mechanism in an operating system that can run a series of steps. After starting a database instance, the Oracle software associates the instance with a specific database. This is called mounting the database. The database is then ready to be opened, which makes it accessible to authorized users.<br/><br/>
Note: The Oracle Automatic Storage Management (ASM) uses the concept of an instance for the memory and process components, but is not associated with a specific database.

Oracle Database (commonly referred to as Oracle RDBMS or simply as Oracle) is an object-relational database management system produced and marketed by Oracle Corporation.<br/><br/>
Originally developed in 1977 by Lawrence Ellison and other developers, Oracle DB is one of the most trusted and widely-used relational database engines.<br/><br/>
The system is built around a relational database framework in which data objects may be directly accessed by users (or an application front end) through structured query language (SQL). Oracle is a fully scalable relational database architecture and is often used by global enterprises, which manage and process data across wide and local area networks. The Oracle database has its own network component to allow communications across networks. Oracle DB is also known as Oracle RDBMS and, sometimes, just Oracle.<br/><br/>

What is Mobile Banking System<br/><br/>
Most banks offer an online bill payment service that lets you pay bills electronically using a secure online account. You then designate the amounts and dates that you want to pay utility bills, credit card payments, loan payments, appointment fees and more. Following are five benefits of using an online bill payment service.<br/><br/>
Mobile Banking Features<br/><br/>
Mobile banking can be used for many of the same tasks that you would complete at a bank branch or on your home desktop computer. These include checking account balances, transferring money from one account to another, finding an ATM, setting up alerts (for example, to notify you if an account balance has hit a certain amount), or viewing account statements.<br/><br/>
In addition to these basic features, mobile banking services may include direct deposit of checks using your device’s camera, paying bills, sending money to another person, transferring credit card balances, or even conducting investment transactions.<br/><br/>
Mobile Banking Is Convenient<br/><br/>
Being able to do most, if not all, of your banking on the go is one of the biggest benefits of mobile banking. No matter where you are, you can “take care of business” without interrupting the rest of your life. Bank branches aren’t going away any time soon, but being able to handle your financial life without having to drive to a branch during open hours can be a real time- and schedule-saver.<br/><br/>
Mobile Banking Keeps You in Control<br/><br/>
Because it’s so easy and so convenient, mobile banking helps keep you in control of your finances. You can monitor your balances and always know where you’re at financially. With account alerts, you can know if your account falls below a certain threshold and instantly transfer money into that account and avoid overdraft fees. You can deposit checks instantly, which is a big help when you need the cash. You can get reminders when to pay bills so you never have to pay a late fee. You can even set up recurring bill payments so you don’t even have to think about when a bill is due. All these features leave you in control of your money on your time.<br/><br/>
Mobile Banking Is Secure<br/><br/>
Mobile banking is as secure. All reputable financial institution use encryption that safeguards and protects your privacy, identity and your financial information. Some institutions even offer a security guarantee to make your use of mobile banking truly worry-free.<br/><br/>
