Database Objects in the Oracle Database Tutorial
The Oracle database’s Learning Objects are used for a number of tasks. Here, we’ll talk about the typical objects that we might utilize when working with Oracle databases on a daily basis.
1.Tables: A Structured Data Storage
The typical items that are utilized as a crucial component of the database are tables. After a table has been made, data should be kept by adhering to the fundamental guidelines for data kinds, values, etc. Simple SQL commands make it simple to access and edit tables that comply with all-important criteria.
2. Views – Limited Data Access
The view notion enters the picture if the database administrator wants to restrict data access. Here, many data views can be defined according to user and business needs.
For instance, if you just want to communicate a small quantity of information with another business, you will need to use the correct SQL instructions to disguise the remaining data.
Only the significant modules that you want to make visible in front of others may be listed by you. The modules that aren’t listed won’t show up and won’t be accessible to users. Views are a type of security that was first introduced and are now widely used.
3. Synonyms – Indicating Objects from Other Databases
Users are able to make references to things that are kept in different locations inside the same or different databases. These are practical objects that can be used in the table with alternate names; all you need to do is set a pointer to the actual table.
The overall storage capacity for database objects is optimized by using this memory management strategy, which allows the reuse of previously used objects. Database programmers have been using the idea to speed up the application code throughput for many years.
4. Code Reusability – Stored Objects
These classes encourage the encapsulation of code for tasks that could be carried out explicitly or implicitly. The best element is that if a task is needed, cached objects can be used repeatedly. Together, it guarantees reliable performance and secure processing.
For the purpose of declaring constants, variables, and cursors for exceptional handling, they can be further separated into procedures, functions, and packages.
