SAP Datasphere - Data Builder types and creation of Tables

 There are different artifacts available in the Data Builder as below.

  1. Table
  2. Graphical View
  3. SQL View
  4. Entity-Relationship model
  5. Analytic model
  6. Data Flow
  7. Replication Flow
  8. Transformation Flow
  9. Intelligent Lookup
  10. Task Chain
Now lets discuss on them in detail.

Tables:
Column structure of the tables can be defined either manually or by using the existing data as template. These are going to get the information from different source systems like flat file / sap / non-sap and can be filled with data from a CSV file or via a data flow.
While creating a table we can define the following:
  1. Technical and Business names
  2. Data Type
  3. Semantic Usage
  4. Label Column
  5. Primary Keys
  6. Default values 
  7. can be/not null
  8. Visibility of the columns
We can also delete current data and upload new data from files and share the current table with other spaces. Hierarchies could be created and the generated CSN annotations could be edited in order to make it synchronize with the expecting changes.


Lets discuss this with some examples of creating a table.

Tables can be created using multiple ways. File upload is one among them.

Creating table using CSV upload:
  1. Go to Data Builder
  2. Select the space under which the table is needed to be created
  3. Click Import -> Import CSV file
  4. Upload the CSV file
  5. Transform data based on the need (Just like SAC)
  6. Click Deploy. This will create and deploy the table in the space.
We can also do the following adjustments in the created tables:
  1. Assign semantic types
  2. Define Primary keys, compound keys, default value, column visibility, associations, field names, data types, descriptions, semantics
  3. Delete and upload new data
  4. Preview and share table with other spaces
  5. Allow to refresh metadata for the definition of a remote table
The tables can also created a-fresh from scratch by clicking on New Table icon in the data builder screen and later we can upload data into the created table.

SAP Datasphere Architecture

Image
  SAP has retained all of the functionality of SAP Data Warehouse Cloud (SAP DWC), while adding new functionality that improves the discovery, modelling and distribution of enterprise data. This evolution has had no impact on the workload of SAP DWC customers. The update is performed automatically, so no migration is required. This will be the case for all new functionalities Accessing and using diverse data from different information systems and locations such as cloud providers, on-premise systems and different data sources has always been a complex challenge for organisations. The processing that this data undergoes in order to centralise it and return it afterwards (extraction, transformation, export, etc.) leads to the loss of its business context. SAP Datatsphere gives its customers the benefit of an enterprise data fabric architecture that harmonises critical data (SAP and non-SAP) in a single way and rapidly delivers meaningful data with business context and logic.

SAP Datasphere Data Integration - Part 1 - Introduction and Integration using Remote Tables

Image
SAP Datasphere provides a large set of default connections to access data from a wide range of sources, source from SAP as well as non-SAP sources or partner tools, residing in an cloud as well as on-premise environment. Connections are defined in a separate view which can be found in the main navigation window of the left. Connections are individual objects in SAP Datasphere. They are created and maintained per SAP Datasphere Space which means only members of a specific Space are able to make use of the related connections. These connections can be then be used within the different tools (like SQL View Builder, Graphical View Builder or Data Flow) for creating your data models. SAP Datasphere can integrate with both SAP or Non-SAP Source systems and it can be either cloud or on-premise. We have multiple connection types in SAP Datasphere. Each connection type supports a defined set of features. Depending on the connection type and the connection configuration, a connection can be used

SAP Datasphere Spaces

Image
  A space is a secure area created by an Administrator, in which members can acquire, prepare, and model data. The Administrator allocates disc and in-memory storage to the space, set its priority, and can limit how much memory and how many threads its statements can consume. If the administrator assigns one or more Space Administrators as members of the space, they can then assign other members, create connections to source systems, secure data with data access controls, and manage other aspects of the space. Spaces are virtual work environments with their own data bases. Spaces are decoupled, but are open for flexible access, thus allowing your users to collaborate without having to worry about sharing their data. To model your data and create stories, you need to start off with a space. You can decide how much and what kind of storage you need, as well as how important your space is compared to other spaces. You also add space members and set up connections here. Each spaces can be
