Right Answer:
A component is a reusable building block in Ab Initio that can perform specific functions, while a transform is a specific type of component that processes data by applying transformations to it.

Right Answer:
In Ab Initio, the different types of joins are:

1. **Inner Join**: Combines records from two datasets where there is a match based on the join key. Only matching records are included in the output.

2. **Left Outer Join**: Includes all records from the left dataset and the matching records from the right dataset. If there is no match, NULLs are filled for the right dataset.

3. **Right Outer Join**: Includes all records from the right dataset and the matching records from the left dataset. If there is no match, NULLs are filled for the left dataset.

4. **Full Outer Join**: Combines records from both datasets, including all records from both sides. If there is no match, NULLs are filled for the non-matching side.

5. **Cross Join**: Produces a Cartesian product of the two datasets, pairing every record from the left dataset with every record from the right dataset.

6. **Self Join**

Right Answer:
Ab Initio handles data partitioning using the "Partition by" component, which allows data to be divided into multiple partitions based on specified criteria, such as key values or ranges. Repartitioning can be done using the "Repartition" component, which redistributes data across partitions based on new criteria, ensuring balanced processing and optimized performance.

Right Answer:

Right Answer:
In ARM Compiler, you use preprocessor directives by starting a line with a `#` symbol. Common directives include `#define` to create macros, `#include` to include header files, and `#ifdef`/`#ifndef` for conditional compilation. For example:

```c
#define MAX_SIZE 100

#include "myheader.h"

#ifdef DEBUG
// Debugging code here
#endif
```

There are two types of system privileges: administrative privileges and object privileges. In SQL Server, you cannot directly add or delete system privileges; they are predefined by the system. However, you can grant or revoke them to users or roles.

Right Answer:
The disadvantages of stored procedures include:

1. **Complexity**: They can become complex and difficult to maintain as business logic grows.
2. **Portability**: Stored procedures are often database-specific, making it harder to switch database systems.
3. **Debugging**: Debugging stored procedures can be more challenging compared to application code.
4. **Version Control**: Managing versions of stored procedures can be cumbersome.
5. **Performance**: Poorly written stored procedures can lead to performance issues.
6. **Security**: They can introduce security risks if not properly managed, such as SQL injection vulnerabilities.
