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:
Common types of linking errors include:

1. **Undefined References**: Occurs when a function or variable is declared but not defined. Resolve by ensuring all referenced functions/variables are defined and linked correctly.

2. **Multiple Definitions**: Happens when the same function or variable is defined in multiple files. Resolve by using `extern` for declarations in header files and ensuring only one definition exists.

3. **Library Not Found**: Occurs when the linker cannot find a specified library. Resolve by checking the library path and ensuring the library is correctly installed and linked.

4. **Incompatible Object Files**: Happens when object files are compiled with different settings or incompatible versions. Resolve by recompiling all object files with consistent settings.

5. **Symbol Conflicts**: Occurs when two or more symbols have the same name. Resolve by renaming conflicting symbols or using namespaces.

6. **Incorrect Link Order**: Happens when libraries are linked in the wrong order, causing dependencies to be unresolved
