SAP HANA Application Certification Practice Tests

Left Outer, Right Outer, and Cross Join:

• Left Outer Join: Retains all records from the left table (or view), and the matched records from the right table (or view). If there is no match, the result set contains nulls on the right side.
• Right Outer Join: Retains all records from the right table (or view), and the matched records from the left table (or view). If there is no match, the result set contains nulls on the left side.
• Cross Join: Produces a Cartesian product of the rows in both tables (or views) resulting in a new table with all possible combinations of rows from both input tables (or views).

Input Parameters in Calculation View:

• They can be bound to multiple attributes within a calculation view.
• They can indeed be used in expressions.
• Value help lists can be assigned to prompt for valid values, guiding users with predefined domain values.
• Technically, they do not result in a WHERE clause but in filters applied to the calculation view context.

Lineage Tool in Calculation View:

• To identify dependent views within a complex transformation chain.
• To trace back to the source of a specific column inside a calculation view.
• To understand the provenance of data (how it's being transformed) in a step-by-step manner.
• The tool can also show who made changes and when the view was activated, providing a historical context.

Functions:

• Functions can have multiple input parameters.
• A function can call another function (recursive or nested functions).
• You can create persistent tables within functions, but this is typically discouraged in favor of a more straightforward design approach.
• Tabular functions must output one tabular structure (though they can return different variants of such structures).

Vector Data:

• Vector data refers to spatial or geographic data types, represented by geometries such as polygons, lines, points, etc.
• The term 'bitmap' in the context of vector data is likely a misunderstanding; vector data is distinct from raster data (bitmaps).
• Graphs are used to represent relationships between entities, not as storage for vector data.

Calling Predictive Algorithms:

• You can call predictive algorithms using a scripted calculation view by writing the algorithm in ABAP or a supported language.
• Predictive algorithms can also be called through table functions and CDS views.
• Flowgraphs are another way to execute predictive analytics, by chaining transformation steps together.

Full Text Search:

• The three types of full text search in SAP HANA are:
  • Fuzzy: Finds matches that allow for a certain degree of deviation (e.g., typing 'love' to find 'lover').
  • Linguistic: Understands the context and semantics, such as synonyms, word forms, etc.
  • Relative: Searches based on proximity of words within a document or text field.
  • Exact: Finds documents that contain an exact phrase or set of keywords.

Other Courses:

• SAP ABAP on HANA Training for Beginners: Covers the basics of ABAP programming with a focus on HANA-specific features.
• Trial ABAP system with HANA database on SAP Cloud Platform: Provides access to a system where you can practice ABAP development with a HANA database.
• SAP ABAP for HANA certification preparation test: A test to assess your knowledge and prepare you for ABAP certification with a focus on HANA features.
• SAP Smart Forms for beginners: Teaches the creation and usage of smart forms in SAP systems, which are used for printing and reporting purposes.
• Additional courses might include advanced topics or specialized modules within the SAP ecosystem, such as Fiori applications development, SAP HANA Cloud Platform services, SAP BW/4HANA, SAP Data Warehouse Cloud, etc.
