Today let’s have a look at the Oracle database and its features, but hold for a second! Before jumping into databases and their amazing features, we should instead start with why we would need a database, as you may know, they are designed to solve problems. So, let’s see how a database can solve problems? Many small businesses start storing the data in spreadsheets. This setup works fine because just having data is not a good reason to have a database. Spreadsheets may lead to some problems.
Here are examples of problems
Size of the Data: A small amount of data can turn into a large amount of data. A spreadsheet is fine when you have 100 records. It may not work if you have 2millon records, you must split up the file into multiple files.
Ease of updating Data: When using spreadsheets or text files, multiple people can’t edit the same file at the same time.
Accuracy: Data accuracy is hard to maintain with no validation of data entry and accuracy is at its stake anyone can write anything
Security: You cannot secure data in spreadsheets and text files as anyone can access these files and can see any data within the files, this solution will not work for payroll and healthcare.
Redundancy of Data: There will be problems of redundancy; multiple copies of the same data will eventually find their way into spreadsheets.
The Integrity of Data: Some of the data that are not considered as important may get entered into the files Because of these problems a database is required, a database prevents these issues.
Before understanding what database means, let’s first understand what data is? In simple words data can be facts related to any objects and those objects can be e.g., Your height, name, age, weight, etc. are some data that can also be in any format a picture, image, file PDF, word document, etc. can also be considered as data.
What is a database?
A database is just a collection of data or information that has been arranged in such a way that it can be accessed, read, modified, and erased with ease. Also, it can be defined as a collection of a set of tables. Each table contains a systematic list of data regarding a single piece of information. For example, a table for services, students, orders, employees, products, For example, a table for services, students, orders, employees, products, and so on. And it is often shown like a spreadsheet, A database’s most fundamental building structure is the table. This is the place where you will put your data, define their data type, and their relationship with the other tables. It consists of rows and columns. In computer science, rows are known as tuples, and columns are known as attributes.
What is Oracle?
Oracle is a powerful relational database software developed by Larry Ellison and his friend Bob Miner and Ed Oates in 1977, Oracle is an American multinational computer technology corporation, The company was founded in Redwood Shores, California, and headquartered in Austin, Texas until December 2020, when it relocated to Texas.
History of Oracle
Oracle has come a long way to become the multibillion-dollar tech giant it is today. Its glorious history can be traced back to the invention and commercialization of computer hardware systems. Oracle’s enterprise software, as well as Oracle itself, Larry Ellison, Bob Miner, and Ed Oates, founded Software Development Laboratories (SDL) in California on June 16, 1977. The first Oracle, written in assembly language and running on a PDP-11 under RSX-11 with 128K of RAM, was released in 1978. Oracle 7 was introduced in June 1992, and it included application development tools, performance improvements, and the ability to save PL/SQL program units as stored procedures and triggers in the database.
Oracle Database Introduction (Oracle DBMS)
We may say that our database is Oracle, SQL Server, Apache Cassandra, or MySQL, but they aren’t databases, they are database management systems (DBMS), it is a collection of programs that enables its users to access the database, manipulate the database & help in the representation of data. The DBMS is software that you can install on your personal computer
Features of Oracle Database
- Scalability and Performance: Features like Real Application Clustering and Portability make an Oracle database much more scalable according to usage.
- Availability: High-performing computing environment is configured to provide data.
- Backup and Recovery: Its layout has complete recovery features to recover data from almost all kinds of failures.
- Security: Securing the data is always the topmost priority. It provides mechanisms to control data access and usage.
Benefits of Oracle Database
When anyone talks about database management software, Oracle is the first pick for most organizations. Let’s look at why Oracle is the best database management system out there.
Portability: Oracle is the best choice when we talk about a portable DBMS solution. It supports more than 100 hardware platforms & 20 networking protocols.
Quick recovery: If your system breaks for any reason, Oracle offers the quickest and easiest online backup and recovery solutions.
Speed and Performance When you’re in charge of a huge database, speed, and performance are crucial. It doesn’t matter how big the database is, Oracle will provide the best speed to access the database.
Other advantages of Oracle database: It offers the main four properties, that all databases must have
- atomicity and durability.
Oracle Vs SAP
Both Oracle and SAP offer good ERP and CRM software products, however, they have various strengths and disadvantages. Oracle excels in a variety of areas but isn’t particularly good in any of them. SAP includes some truly remarkable capabilities, as well as some that are only adequate. Oracle, for example, has strong marketing capabilities, including the ability to manage campaigns from a single platform. SAP does a passable job in this area, providing cross-functional finance, procurement, and marketing procedures. Campaigns and budgets can be planned, but it’s still not as good as Oracle’s setup.
