Oracle-Corporation
Oracle-Corporation is one of the largest providers in the Enterprise I-T market.or the abbreviated name of its flagship product a relational database management system RDBMS that is formally called Oracle Database. The database software is at the center of many corporate IT environments, and supports a combination of transaction processing, business intelligence and analysis applications.
In 1979, Oracle-Corporation. was the first company to market an RDBMS platform, and remains the leading database provider by a wide margin in terms of revenue. Driven primarily by Oracle Database sales, it had a 40.4% share of global database software revenues in 2016, according to Gartner; That was two percentage points less than in 2015, but still twice the percentage of Microsoft’s second place.
In the following decades after the launch of RDBMS technology, Oracle-Corporation greatly expanded its product portfolio through internal development and numerous acquisitions. Now it also sells several other databases, multiple lines of commercial applications, data analysis software, middleware, computer systems, data storage equipment, development tools and other technologies. In addition, Oracle is working to establish itself as a leading cloud computing provider, after initially being slow to adopt the cloud.
But Oracle Database is still the technology most commonly associated with the company; It is also the main data management platform for Oracle-Corporation applications and the data warehouse, BI and analysis systems that Oracle offers to customers.
What is Oracle?
A database is an organized collection of data. The data can be textual, such as orders or inventory data, or it can be images, programs or anything else that can be stored on a computer in binary form. A relational database stores data in the form of tables and columns. A table is the category of data such as, Employee or the columns, are Information about the category such as, name or address; Some databases have a minimum set of features and only store data, while others include programming languages, facilities and utilities to support enterprise-level applications such as Oracle is the 1 database or has the most advanced feature set. In almost all relational databases data is accessed through to PL / SQL is a programming language like PL / SQL is a feature-rich language oriented to the development of database applications. PL / SQL is the procedural language of the database, but it is also the procedural language for most Oracle Developer is a 4GL GUI application generator. with Developer, you can create forms reports or graphics.HTML DB is a fairly new application generator geared towards web development (added to the database with version 9iR2).
ERP and data storage.>>
Oracle-Corporation is made up of a set of processes that run on your operating system. These processes manage How data is stored and how it is accessed as. I will cover these processes in detail in the future; But for now we just have to understand that ( Oracle) is a program that runs in the background, maintains its data and determines where it should go on your hard drive. SQL, and structured query language, and Oracle is no exception. SQL allows you to SELECT your data, C- Java or Oracle-Corporation tools. Programs that run within the database are called stored procedures. These stored Procedures are almost always PL-SQL, but can be written in Java as. Some of the Oracle tools to access the database and create programs are: Pascal, In the world of Oracle-Corporation, there is no better way to access your data from a program. SQL can be natively integrated into PL / SQL programs. I will use SQL and PL / SQL to a large extent in my future articles. INSERT new records, UPDATE existing records and Oracle-Corporation* Forms and Oracle * Reports are two components of Oracle Developer. Earlier versions created client-server applications, but the latest versions create web applications that run under Oracle Application Server (OAS). OAS is a web based application server sold by as Oracle. The OAS is Licensed, separately or is very Expensive as are its closed source competitors The current version is HTML DB does not need an application server. This tool runs from the database and can be presented on the web using the Apache web server that comes with the database. As this is not an additional license, it provides a cheaper way to develop applications. Developer is a thick, feature-rich client with all normal Oracle-Corporation Enterprise Manager is the Enterprise GUI tools to manage the database. From this tool, you can perform any action in the database that is necessary. This tool is mainly used for administration, but can also be provided to developers for the adjustment and monitoring of applications. In Oracle 10g, OEM also provides grid control. GUI widgets.HTML DB is based on HTML and is very thin and limited to the widgets provided by HTML. OEA 10g DELETE the records you want to get rid of. SQL can be integrated into other languages or you can run SQL scripts directly in the database. PL / SQL is the extension of the procedural language for SQL.
SQL * Plus has a command line interface. With it, you can access the database and write stored procedures, you can execute SQL commands to retrieve data and you can execute embeddedSQL, PL / SQLor SQL * Plus scripts, or a combination of those three things.
There are also many third-party tools to access the database. For our purposes, our main tool for data access will be SQL * Plus. In the future, I will cover the creation of applications with HTML DB and access to your data with some third-party tools.
How about Java?
Oracle has a technical website called My next article will cover the download of Oracle 10g and its installation. As a side note, Oracle provides all of its software with a developer license. This license allows you to try the software for free. You cannot create production applications without a paid license, but development with the tools is acceptable. I am not a lawyer, so I recommend that you review the license when downloading any In addition, a note about version control in Javais the current hot language especially on the web server. I will also be a covering Java in the database in future articles. Java is natively compatible with Oracle-Corporation. Technically, I could use Java to create your stored procedures if you wish, but I am not an advocate of that. When you work within the database, I think you should only turn to Javawhen you cannot perform a task in PL / SQL. As you will see, there is very little that I cannot achieve withPL / SQL. It will be difficult to learn Oracle if you can’t play with it.
So where can you get access to this software?
OTN (Oracle Tech Net) that provides access to all Oracle-Corporation software and all documentation for that software. There are also forums and many other tools to help you learnOracle. You have to register to access, but registration is free. Go to OTN software. http://otn.oracle.com/ and get an ID today. In future articles, I will spend a lot of time accessing this website to download software and documentation. Oracle-Corporation; All products launched by Oracle have a version. The current version of the database is 10g release 1 also written as10gR1 In addition to this semantic release name each release has a numerical version. The numerical version for 10gR1 is 10.0.1.3.
