What is a data store object?

A BW DataStore Object is the object which represents a flat physical table. In a dataflow, it is typically used as an Enterprise Data Warehouse layer, to store (historical) transactional data before it is transferred to the reporting layer. It is also the object where the delta is processed and SID’s are generated.

What is Data Store object in SAP BW?

A DSO (DataStore Object) is known as the storage place to keep cleansed and consolidated transaction or master data at the lowest granularity level and this data can be analyzed using the BEx query.

Where is SAP data stored?

The SAP HANA database supports two types of table: those that store data either column-wise ( column tables ) or row-wise ( row tables ). SAP HANA is optimized for column storage.

What is object storage example?

Examples of Object Storage Unstructured data such as music, images, and videos. Backup and log files. Large sets of historical data. Archived files.

Is object storage a database?

What is object storage? Object storage, often referred to as object-based storage, is a data storage architecture for handling large amounts of unstructured data. This is data that does not conform to, or cannot be organized easily into, a traditional relational database with rows and columns.

What is Advanced Data Store object?

The DataStore object (advanced) is the central object for data storage and data consolidation in the BW system. The DataStore object (advanced) can contain InfoObjects and fields. This allows you to load data into the BW without having to assign InfoObjects.

Is SAP an SQL database?

SAP HANA and Microsoft SQL are relational database management systems developed by SAP and Microsoft respectively. The latest versions of both systems are SAP Hana 2.0 and Microsoft SQL Server 2019 respectively.

How does SAP store data?

There are two types of Relational data stores in SAP HANA: Row Store and Column Store. It is same as Traditional database e.g. (Oracle, SQL Server). The only difference is that all data is stored in row storage area in memory of SAP HANA, unlike a traditional database, where data is stored in Hard Drive.

Is object storage a file system?

Unlike file storage, object storage does not follow a hierarchical structure. The metadata contains description about the data and the unique identifier is used to easily retrieve the object instead of a file name and file path. Object storage is a more recent approach that doesn’t impose a file system on the data.

What is the difference between object and file storage?

File storage organizes and represents data as a hierarchy of files in folders; block storage chunks data into arbitrarily organized, evenly sized volumes; and object storage manages data and links it to associated metadata.

What is difference between LSA and LSA ++?

The biggest difference between SAP’s earlier LSA and the above HANA LSA++ is the fact that queries can be directly built in BW on HANA on the DSO level and the additional layer of an Infocube/Multiprovider is not needed. This eliminates data redundancy and huge cost savings in terms of daily maintenance.

How are infocubes converted to datastore objects?

As we have seen with the conversion of a DataStore object, groups are used to model the dimensions. The InfoProvider properties are not stored with the DataStore object (advanced) as these properties are related to queries. Such properties as read mode and cache mode of queries are now directly modeled in the query itself.

What is an infocube and what does it do?

Infocube is data storage area in which we maintain data which we are extracting from source system physically. An InfoCube can function as both a data target and an InfoProvider.

What’s the difference between info providers and info cubes?

Info Providers are the objects in BW, which are storing data physically or virtually give access to the data. They can be accessed for reporting purposes. – Data Store Objects – stores transaction data on detailed level. – Info cubes – stores transaction data on aggregated level. Info cubes are using the well known star schema.

How is an infocube used in a staging system?

An InfoCube is used to store the data physically. It consists of a number of InfoObjects that are filled with data from staging. It has the structure of a star schema. The real-time characteristic can be assigned to an InfoCube. These Real-time InfoCubes are used differently to standard InfoCubes.
