Difference Between

NETCA vs DBCA   In ORACLE, there are configuration assistants for separate tasks. NETCA and DBCA are two of the very important assistants. These assistants are Graphical User Interfaces (GUIs), which can be easily used. What is NETCA? NETCA stands for NET Configuration Assistant. This is a JAVA based GUI tool in... 

Oracle Standard Edition (SE) vs Enterprise Edition (EE)   ORACLE database products are in five different editions. Each of these editions has a set of features related to performance, availability, scalability, and security areas. ORACLE EE contains all of those features and other editions have lesser features... 

BCNF vs 4NF (4th Normalization)   Database normalization is a technique, which is dealing with relational database management systems. Data errors can be avoided in a well normalized database. Normalization is used to reduce the data redundancy of the database. That means implementing database tables and... 

ORACLE Export (exp) vs Datapump (expdp)   ORACLE provides two external utilities to transfer database objects from one database to another database. Traditional exports (exp /imp) are introduced before 10g. Then from 10g, ORACLE introduced datapump (expdp / impdp) as an enhancement to traditional export utility. Traditional... 

ORACLE Dataguard vs Real Application Cluster (RAC)   RAC and Data guard are very important topics in Oracle High Availability. Both of these architectures have many enhancements in Oracle 11gR2 than the 10g and 9i. ORACLE recommends having a combination of RAC and data guard to get the maximum benefit of data level... 

Stored Procedure vs Function   Stored procedures and functions are two types of programming blocks. Both of them must have calling names. Those calling names are used to call them inside another programming block like procedures functions and packages or SQL queries. Both of these object types accept parameters... 

View vs Table   Views and tables, both are two database object types. In simple words, Views are stored or named select queries. They can be created as shown below. Create or replace view view_name  As  Select_statement; Tables are made up of columns and rows. A column is a set of data, which belongs to a same... 

View vs Stored Procedure   Views and stored procedures are two types of database objects. Views are kind of stored queries, which gather data from one or more tables. Here, is the syntax to create a view create or replace view viewname as select_statement; A stored procedure is a pre compiled SQL command set, which... 

Synonym vs Alias (in ORACLE databases) | Private synonyms and Public synonyms   In English, synonym and alias have nearly the same meanings. But in databases those are two different things. Especially in ORACLE databases, both of their usage is different. Synonyms are used to refer objects of a schema or a database... 

Archival vs Backup | File archiving and Database archiving, Hot backups and Cold backups   Archiving and backing up are two main topics related to databases. Backups are used as a database disaster-recovery solution. Archives are used to store a specific version of a table data or a file, or separate/move a set... 

View vs Materialized View   Views and materialized views (mviews) are two types of oracle database objects. Both of these objects refer select queries. These select queries act as virtual tables. Normally views and mviews refer large select queries, which have set of joins. Therefore, one of the main advantages... 

Normalization vs Denormalization Relational databases are made up of relations (related tables). Tables are made up of columns. If the tables are two large (i.e. too many columns in one table), then database anomalies can occur. If the tables are two small (i.e. database is made up of many smaller tables), it would... 

Delete vs Truncate Both SQL (Structure Query Language) commands, Delete and Truncate are used to get rid of data stored in tables in a database. Delete is a DML (Data Manipulation Language) statement and it removes some or all the rows of a table. The ‘Where clause’ is used to specify the rows that... 

Delete vs Drop Both Delete and Drop commands belong to SQL (Structured Query Language) statements, and they are used in case of removing data from a database. Delete is a DML (Data Manipulation Language) command. It deletes some or all the data from a table according to the condition that the user has specified.... 

3NF vs BCNF Normalization is a process that is carried out to minimize the redundancies that are present in data in relational databases. This process will mainly divide large tables in to smaller tables with fewer redundancies. These smaller tables will be related to each other through well defined relationships.... 

1NF vs 2NF vs 3NF Normalization is a process that is carried out to minimize the redundancies that are present in data in relational databases. This process will mainly divide large tables in to smaller tables with fewer redundancies. These smaller tables will be related to each other through well defined relationships....
