In the HANA database, each SQL statement is basically implemented in the reference of the transaction. Therefore in the further process, the new session is allotted to a new transaction.
Posted Date:- 2022-02-15 07:22:49
The role of the transaction manager is to coordinate the database transactions. He also keeps a record of running and closed transactions wherever possible. When the transaction is rolled back or is committed, it’s the duty of the transaction manager to notify the involved storage engines and about the event so that the necessary actions can be processed.

One of the most important advantages of SAP SLT is
It works on trigger-based approach. Therefore such an approach has no measurable performance impact in the source system.
This also offers to filter the capability and transformation of data.
It offers the real-time data replication.
It is fully integrated with the HANA studios.
Posted Date:- 2022-02-15 07:19:21
In the Advanced Replication settings, a transformation rule is specified. It is designed in such a way that transaction for source tables is transformed during the replication process. For example, users can specify a rule in case of Converting the fields, to fill empty fields and also to Skip the records.

A Sap Hana database user is protected in the first place with a password. However, a password is very often required at the command line in order to connect and execute a batch or an SQL script. The username and password are then visible to anyone. In order to avoid that situation, it is possible to create a special key in relation to a particular user. Username and password are then invisible via the use of that key.

It is actually an important later in SAP HANA which plays a very important role. Actually, HANA has a computing engine built inside and the users have to utilize the data directly without taking any backup. The same can create an issue during powerful failure and thus it is necessary to keep a backup of the same. This layer comes as a savior and it make sure no loss of data during such a situation.

Under Quick Launch, Generate Time Data option allows the consumer to develop the Time data so that it can be employed for designing the Time-based Attribute Views.
When you select Generate Time Data, you will be supplied with two options:
<> Gregorian: Mostly the data will be rendered based on From and To years alongside the granularity - Second, Minute, Hour, Day, Month mentioned.
<> Fiscal: In this circumstance, the time data will be rendered based on the variant described (some organizations may use their time).
Standard tables T005T, T005U, T009, and T009B in SAP HANA are needed if you opt for the Fiscal type.

To structure and specify the relationships among attributes in a modelling view. Hierarchies are implemented.
Companies describe hierarchies for classification of information, letting roll-up and drill-down analysis. For instance, a sales company might assign a salesperson to a country and a country is assigned to a region. Then the sales data can be calculated and scrutinized by region, country, or salesperson.
There are two kinds of hierarchies:
<> Level Hierarchies are rigid hierarchies, where you can access the root and the child nodes in the defined order. For instance, organizational structures.
<> Parent/Child Hierarchies are regarded as value hierarchies, i.e, hierarchies obtained from the value of a node. Such as a Bill of Materials (BOM) includes Assembly and Part hierarchies, and an Employee Master record includes Employee and Manager data. The hierarchy can be analyzed on the basis of a selected parent, also, there are scenarios where the child can be a parent

If tables of a schema for example SCHEMA_ABC are implemented to create the modelling views, then the following SQL statement must be performed before starting any such modelling views.
GRANT SELECT ON SCHEMA SCHEMA_ABC TO _SYS_REPO with the option of GRANT
Consider _SYS_REPO as “the activation guyâ€. It takes your models and makes the required runtime objects from them. Thus user _SYS_REPO requires the allowance to choose YOUR tables/views. (If _SYS_REPO user is unable to decide on the tables added in the from-clause of the view-definition, it will fail to describe that view). If different customers require to choose this view (It is quite obvious this is always the scenario, else the views would not make any sense), then _SYS_REPO ought to have the extra allowance to grant the selection further (with the grant option).
After all your models that access data in your schemas has been activated, _SYS_REPO wants to offer you and other users read access to the activated models.

In HANA, there are 3 kinds of schemas.
<> User-Defined Schema: These are developed by the user, DBA or System Administrator
<> SLT Derived Schema: During the configuration of SLT, it develops the schema in the HANA system. All the tables imitated into the HANA system are included in this schema
<> System Defined Schema: System Defined schemas are provided with the SAP HANA database and include information on the HANA system. _SYS_REPO, _SYS_BIC, _SYS_BI, _SYS_STATISTICS are the system schemas.

Activate – Implement the inactive objects.
Redeploy – Implements the active objects in any of the scenarios:
If your runtime object becomes corrupted or deleted, and you need to build it again.
If your runtime problems while object activation, and the object status shows active.
Posted Date:- 2022-02-12 08:15:50
When an object is activated, it becomes accessible for reporting and analysis. After the view has been successfully activated, a run-time object is built in the _SYS_BIC schema.
For instance, let’s say there exists a calculation view CV_VIEW1 in package “MyPackageâ€. After this view is activated, a run time object (column view) will be developed in _SYS_BIC schema having the name “MyPackage/CV_VIEW1â€. This column view is implemented while performing the data preview of the calculation view.

Normalization is nothing but the process that is adopted for the purpose or removing the redundant data from the database. This is generally done by splitting the table into different sections. This actually makes sure of integrity. On the other side, the de-normalization is the process of considering the redundant data so that all the queries which are complex can be enhanced in terms of overall performance.

>> This engine will be called in the backend whenever we run any queries on Analytic Views in SAP HANA.
>> If there are no additional calculations performed like calculated columns, restricted measures and counters, then everything will be processed in OLAP Engine.
>> OLAP Engine acts as join engine for those Attribute Views used in Analytic Views, without any calculated columns
>> All the join engine work will be converted into ‘BwPopJoin’ which is part of OLAP Engine.

Posted Date:- 2022-02-12 08:07:57
Different types of nodes, they are:
>> Join: This node is used to join two source objects and pass the result to the next node. The join types can be inner, left outer, right outer and text join.Note: We can only add two source objects to a join node.
>> Union: This is used to perform union all operation between multiple sources. The source can be n number of objects.
>> Projection: This is used to select columns, filter the data and create additional columns before we use it in next nodes like a union, aggregation and rank.
>> Aggregation: This is used to perform aggregation on specific columns based on the selected attributes.
>> Rank: This is the exact replacement for RANK function in SQL. We can define the partition and order by clause based on the requirement.
