Database
management and database have been improved with high security, workload
management and availability along with Data Integration, Data Quality and
Enterprise Modeling. When a professional is deploying or developing modern
applications which are able to access data from anywhere and integrate
transactions with analytical processing of an advanced nature. SAP HANA 2 has
revolutionized analytical intelligence an application development. There are
highly significant changes in terms of analytical processing engines for
spatial, text, graph and streaming data along with Enhanced Development tools
and application server tools.
SAP
HANA requires the availability of a Cryptographic service provider as a
prerequisite for encrypting the data volume. (Learn HANA from experts in SAP HANA training course by Learn IT
Training) This occurs by default as recommended by the Common CryptoLib. In
this case, a persistence root encryption key must be created. This key is utilized
to encrypt the page encryption key and is stored in SSFS and automatically
retrieved from there. This makes sure that no administrator action is needed
for start-up.
Both
SAP HANA 1.0 and SAP HANA 2.0 do not support the encryption of database traces
and data backups. It should also be noted that for encrypting data backups a
suitable third-party tool must be utilized with the backint interface. And the
same should be applied to the database trace, which are not encrypted either. A
great generic recommendation is to avoid large tracing files on Operating
System level.
Given
below are the improvements and enhancements that are seen in SAP HANA 2.0 over
the previous version:
Database Enhancements bring
simplified management of tenants and the establishment of multi-tenant database
containers (MDC) as the default installation, with the choice to operate as a
single DB.
Analytical Intelligence Enhancements include
a new JSON document store to gain new insights by processing structured and
semi-structured data within the same database. We continue to expand our focus
on machine learning with additional machine learning algorithms and adding the
ability to apply trained decision trees to streaming data.
Application
Development and Tools Enhancements allow you to accelerate the development of new applications
with intuitive interfaces tailored to the needs of each user with support for
Fiori Launch Pad (Know about Fiori launchpad from SAP FIORI training) in SAP HANA Extended Application Services,
Advanced (XSA). Additional troubleshooting and compliance features, a new
central persistence object Data Warehouse (DW) use cases, and expanded SQL/SQL Script (Learn from SQL server training) simplify
development and expand use cases.
Search
- Run search rules in “Batch Mode” to go through a large number of records in a single call.
- Find information at an accelerated rate with enhanced filtering and searching on dates.
- Dynamically configure search rules for duplicate detection.
- Leverage the intelligence of existing applications that utilize text analysis to all languages by utilizing spaces between words.
- Manage your own domain-specific custom dictionaries and rules within the Web IDE for SAP HANA.
- Effortlessly embed natural-language processing into user products with a new native SQL interface.
- Analyze graph data with the highest efficiency to achieve accelerated results with new visualizations.
- Take advantage of existing Cypher query language skills with SAP HANA support for Cypher for pattern matching.
- Creation of richer predictive applications utilizing more pre-packaged algorithms.
- Run scoring functions at an accelerated pace with parallel processing across large-scale partitioned data.
Application server
- Minimize TCO with Bring Your Own Language and Runtimes by running these applications within the XS Advanced framework.
- Construct native applications in multi-tenant or MDC landscapes without constraints.
- Minimize effort of supporting JAVA based applications with enhanced JAVA / JavaScript runtime supportability and trace features.
- Test and develop MDX based queries and statements against SAP HANA views and take advantage of additional MDX capabilities.
- Speed up application development with improved modeling for data types (i.e. spatial, text, graph, etc.), calculation views and core data services.
- Boost productivity with enhanced syntax error troubleshooting and extended impact and lineage analysis.
- Directly generate and query hierarchies without dependency on the graphical modeler.
SAP Enterprise Architecture Designer,
Edition for SAP HANA Execute enterprise architecture and business process
modeling, along with architecture and plan physical data models that target SAP
HANA, with this new web-based tool that compliments existing SAP HANA modeling
tools.
Multi-tier storage
- Integrated management of Dynamic Tiering with support for encrypted extended store, delta back-ups and system replication.
- Simplification of management for large volumes of data with multi-store tables.
- Gaining access to higher number of data sources with added support for Microsoft Access and SharePoint.
- Simplification and acceleration of data movements with parallel data loads, automatic recovery, and data integration with SAP ABAP-based systems (via BAPIs that support virtual procedures).
- Leveraging remote metadata synchronization to simplify alignment with remote data schema copies.
- Enhance the accuracy of location-based data by leveraging enhanced address cleansing capabilities.
The
most remarkable feature of HANA is that redo log encryption is possible. Post
activation, log entries undergo encryption using a 256 bit long root key. This
key can be considered as another key for data volume encryption and must also
be maintained separately. Users have to remember that there is the distinct
possibility and or need to back-up encryption root keys with HANA 2.0 for
example in the case of redo log encryption.
Such
a root key back-up may be required for recovery when it comes to a disaster
scenario. If the root key back-up is lost, then it may lead to a situation
where the data is unrecoverable. Hence it is recommended to perform a root key
backup at periodic intervals. If users lose the root key then it may lead to a
situation where the data is unrecoverable. While carrying out root key back-ups
are highly recommended, this leads to the requirement of a new root key backup,
every time the root key is changed. Along with this, a password will
secure the changing root key, and the required password is supposed to be set
before the root key back-up is executed.
SAP
HANA has always been recognized as the leader in database management systems
and as database servers. While SAP HANA 1.0 has a strong set of core features,
SAP HANA 2.0 builds on these great foundation features with superior sets of
enhancements in everything from data management and advanced analytical
processing to Application development and tool enhancements.
