The business sector is a field which embraces technology. The sector is constantly in flux because one needs to make the most of novel opportunities to finish first. In such a competitive sector, certain skills are high in demand due to their wide range of applications, and SQL is one of them. And out of the various SQL Developers available, Oracle offers a powerful yet versatile platform suitable for SQL programming.
Structured Query Language - A Widely Accepted Programming Language!
SQL is called so because it uses queries as part of its code. Queries are commands used to manipulate data. Another salient feature of SQL is that it is a structured language, and all data is assumed in a tabular format. These features make it the perfect tool for business purposes, and it has found rising popularity in the same.
SQL Developer is the platform on which you can code, compile and execute various programs in SQL.
Oracle SQL Developer - A Robust Platform
Oracle SQL Developer is an IDE for programming in SQL on Oracle Databases. It is made available by the Oracle Corporation for free and is one of the most popular Relational Database Management Systems today.
Even though all such platforms use SQL, many differences make some better than the other. SQL itself comes in different types, so these programs are diverse in their capabilities. This is because different platforms use different forms of SQL and follow different protocols and mechanisms.
Oracle and PL/SQL - A Powerful Integration
Oracle SQL Developer uses a version of SQL called Procedural Language or PL/SQL, whereas most others, especially Microsoft SQL Server uses T-SQL. This itself gives Oracle an edge over its counterparts, as PL/SQL has many advantages over other formats.
For starters, PL/SQL is different from T-SQL in its syntax as well as capabilities, since they both handle variables, stored procedures and built-in functions differently. PL/SQL can also create packages of grouped procedures, unlike T-SQL.
This also makes it easier to convert applications to a different database without posing many challenges in editing or reworking the code. PL/SQL also has much more DBMS system packages than T-SQL and is better at error exception handling.
Organizing Database objects in Oracle - Highly Structured
Another major feature of Oracle which makes it more desirable is the way Database objects are organized in Oracle. Oracle has a subgroup of collection of database objects under a schema. There are many such Schemas, and they are all shared with the users. The sharing is universal but can be regulated through permissions.
Oracle works across all platforms and operating systems. This makes it a viable option for enterprises running on custom operating systems or freeware.
Transactions are a group of tasks that must be treated as a single unit. These are executed differently in different platforms, and Oracle is more in control of its transactions. Oracle treats each new database connection as a new transaction. As each query is executed, the changes made are only in memory until an explicit statement is given. Upon issuing the COMMIT statement explicitly, the changes are permanently made. This offers great flexibility as you can easily roll back changes and correct errors.
Oracle also has a wider variety of options to choose from in DBMS packages. Other options like Microsoft SQL Server does not contain provisions to declare some object types like public and private synonyms, independent sequence objects and so on. Therefore, Oracle is a more comprehensive option as it covers all the bases.
A cluster of servers refers to a connected group of physically separate servers that act in harmony and are perceived as a single system by networks. This helps in up-scaling by increasing computing power. Oracle can take advantage of Clustered systems, unlike their peers. With the new parallel servers in Oracle, you can place any application on a cluster without affecting the application, and it can be up-scaled by adding another server. This puts it miles ahead of its competing platforms.
Working with computers on anything can be quite a hassle. Even in simple cases such as writing this article, one mistake can cause you to lose all your progress. Therefore, applications have to be reliable in all aspects.
Oracle has many features that ensure a smooth work-flow and contains safeguards against any unexpected issues. It allows you to mirror transaction log files, which show exactly what programs were executed and when. It also prevents crashes occurring as a result of less space on the hard disk, and saves the server from downtimes and rebooting. This makes Oracle a safe option when compared to other DBMS platforms.
Oracle: A Powerhouse
The above-mentioned features show exactly why Oracle is a more desirable option over its competitors. As a freeware, it is readily available. It also has a wider assortment of DBMS packages and options to choose from and is much more flexible. SQL Programming in Oracle works with every platform and OS. It is also more reliable and versatile as a platform, and the Clustering feature alone puts it at the top of the table.
