Introduction To SAP HANA Database- For Beginners

SAP HANA Database:

SAP HANA is an in-memory database:

- It is a combination of hardware and software made to process massive real time data using In-Memory computing.- It combines row-based, column-based database technology.- Data now resides in main-memory (RAM) and no longer on a hard disk.- Its best suited for performing real-time analytics, and developing and deploying real-time applications.

An in-memory database means all the data is stored in the memory (RAM). This is no time wasted in loading the data from hard-disk to RAM or while processing keeping some data in RAM and temporary some data on disk.Everything is in-memory all the time, which gives the CPUs quick access to data for processing.

The speed advantages offered by this RAM storage system are further accelerated by the use of multi-core CPUs, and multiple CPUs per board, and multiple boards per server appliance.

Complex calculations on data are not carried out in the application layer, but are moved to the database.

SAP HANA is equipped with multiengine query processing environment which supports relational as well as graphical and text data within same system. It provides features that support significant processing speed, handle hugedata sizes and text mining capabilities.

So is SAP making/selling the software or the hardware?

SAP has partnered with leading hardware vendors (HP, Fujitsu, IBM, Dell etc) to sell SAP certified hardware for HANA. SAP is selling licenses and related services for the SAP HANA product which includes the HANA database,easy to use data modeling tool called HANA studio and other software to load data in the database.

SAP HANA Architecture

With the help of technology like SLT replication, data can be moved to HANA in real time. It is also possible to copy data from SAP BW or other database into SAP HANA. In HANA, we can use modeling tool called HANA Studioto build the logic and structures and use tools e.g. SAP BusinessObjects, SAP Visual Intelligence to visualize or analyze data.

Want to know more about SAP HANA Architecture? Check this.An insight into SAP HANA ArchitectureCan I just increase the memory of my traditional Oracle database to 2TB and get similar performance?

NO. You might have performance gains due to more memory available for your current Oracle/Microsoft/Teradata database but HANA is not just a database with bigger RAM. It is a combination of a lot of hardware and softwaretechnologies. The way data is stored and processed by the In-Memory Computing Engine (IMCE) is the true differentiator. Having that data available in RAM is just the icing on the cake.SAP HANA Database: Business Value Proposition

I have a doubt, I am a fresher and have no idea about HANA. All the data is stored in RAM , but it is a volatile memory so once if we restart the system, all the data will be erased, right? Cananyone explain how HANA overcomes this problem?

Hi Minakshi,SAP HANA is in-memory database and all the data resides in RAM. but it also has a disk memory just for backup.

Hi Admin,

Hope you are doing well.

Actually i am working as DWH Engineer with skill set OBIEE,Informatica.

Is this experience useful to learn SAP HANA?Is SAP HANA replace SAP BW?(Becuase i want to learn SAP BW).

Thanks,Hanumantha Reddy.M

Hi Hanumantha,Learning SAP HANA actually does not need much prerequisites. You can start learning with even with a basic knowledge of database.

SAP HANA is not actually replacing SAP BW. There is something called SAP BW on HANA which is quite popular now a days. It combines the power of both.You may Read: http://saphanatutorial.com/sap-bw-on-hana/

Thank you for your post! SAP HANA offers enterprises a new approach to harnessing the value of all that corporate data. As mentioned above, HANA runs on inexpensive commodity hardwarefrom any of several SAP partners, including IBM, Dell, and HP. Its data replication and integration capabilities vastly speed up the process of loading data into the database. And because ituses in-memory storage, applications on top of HANA can access data in near-real time, meaning end-users can gain meaningful insight while there is still time to take meaningful action.HANA can also perform predictive analytics to help organizations plan for future market developments.

Hello Admin,

I am from engineering background and have 5 years of work experience in technical support(servers, windows,desktop,etc). I have never been involved into programming or coding though Ihave a technical bend and zeal to learn such stuff. Have knowledge on databases, MSQL server. I am currently working as remote desktop engineer and keen to move to the SAP HANAtechnology for which have done lot of homework on it. I am also taking the SAP classes for HANA inplementation and modelling. I have a few queries in my mind. I would really appreciate ifyou could answer those for me.

1) Considering my background, is it worthwhile for me to move to the SAP HANA technology taking into consideration the scope of opportunities in this domain.2) Is it okay to complete SAP HANA training from institutes other than the SEIMENS?3) What is the percentage of females working for this technology? Is it going to be a nice field for females as we hardly find in such technologies?4) What is the difference between HANA development and implementation? Which one is more challenging and got more opportunities in near future? As I mentioned, I am inclined towardscoding and programming concepts, however, without prior knowledge and experience, is it advisable to go for HANA development or is implementation and modelling fine for me?

Thanks in advance!

Hi Poonam,1) Considering my background, is it worthwhile for me to move to the SAP HANA technology taking into consideration the scope of opportunities in this domain.> Considering the job trend and future market, yes it is worthwhile to move to SAP HANA technology.

2) Is it okay to complete SAP HANA training from institutes other than the SEIMENS?> The institute from where you learn does not matter a lot provided they have good faculties and provides hands-on exercise. However, it will be a good idea to take acertification on HANA.

3) What is the percentage of females working for this technology? Is it going to be a nice field for females as we hardly find in such technologies?I do not thing gender has to play any role here Work environment in almost all IT companies are quite good and lots of female colleagues are working here.

4) What is the difference between HANA development and implementation? Which one is more challenging and got more opportunities in near future?SAP HANA Development It is basically developer role where you will be responsible for developing modeling views, procedures, services etc.Check the course: http://saphanatutorial.com/sap-hana-online-training-sap-hana-advanced-modeling/

SAP HANA Implementation/Administration This is admin role you you will be responsible for HANA installation, support and maintenance. This job profile does not includedevelopment but rather support. Currently there are many companies looking for HANA administrator and you can easily grab a good opportunity.Check the course: http://saphanatutorial.com/sap-hana-administration-course/

The decision should be based on your interest. If you are interested in development then go for SAP HANA Development. But if you are interested in HANA Operation, supportand maintenance then go for SAP HANA Administration.

One last piece of information that might affect your decision currently job requirements for SAP HANA Administration are comparatively more. But there are still quite goodopportunity for HANA Developers.

Regards,Admin
