TMAP has three types of matching: exact, fuzzy, and partial. TUNITE is used for merging data from multiple sources.

• TMAP has exact, fuzzy, and partial matching options for data mapping

• Exact matching requires exact match of values in source and target

• Fuzzy matching allows for some variation in values, such as spelling errors

• Partial matching matches based on a percentage of similarity between values

• TUNITE is used for merging data from multiple sources into a single output

• TUNITE ...read more

tJava, tJavaFlex, and tJavaRow are components in Talend for Java programming.

• tJava is used for writing custom Java code in Talend jobs.

• tJavaFlex is used for writing complex Java code in Talend jobs.

• tJavaRow is used for writing Java code to manipulate data in Talend jobs.

• All three components require Java programming knowledge.

• Examples: tJava can be used to perform calculations, tJavaFlex can be used to create custom functions, and tJavaRow can be used to filter data.

Right outer join returns all records from the right table and matching records from the left table.

• It includes all the records from the right table and only matching records from the left table.

• If there is no match in the left table, the result will contain NULL values.

• It is denoted by RIGHT OUTER JOIN or RIGHT JOIN keyword in SQL.

• Example: SELECT * FROM right_table RIGHT JOIN left_table ON right_table.id = left_table.id;

Types in Oracle are data types that define the type of data that can be stored in a column or variable.

• Arrays can be one-dimensional or multi-dimensional

• Elements in an array can be accessed using an index

• Arrays can be initialized with a fixed size or dynamically resized

• Examples of array types include int[], double[], and string[]

tJava, tJavaRow, and tJavaFlex are all components in Talend that allow for custom Java code to be executed within a job.

• tJava is used to execute Java code within a job, and can be used to manipulate data or perform custom logic.

• tJavaRow is similar to tJava, but is used specifically for manipulating data row by row.

• tJavaFlex is a more advanced version of tJava that allows for more complex Java code to be executed within a job.

• All three components require knowledge of Java prog...read more
