In addition to all the regular confusion around SAP issues might also stem form the fact that SAP used to have their own DBMS      It used to be called Adabas  marketed originally by Nixdorf and then by Software AG  and was a quite popular DBMS for smaller SAP  the ERP solution  installations in Germany  At some point  AFAIK around 2000  SAP started to co-develop support take over Adabas and marketed it as SAP DB and later MaxDB under commercial and open-source licenses  There also was is some agreement with MySQL   But when people talk about SAP  they usually refer to the ERP solution as the other posters have noted

I have worked with SAP since 1998  SAP is a type of software called ERP  Enterprise Resource Planning  that large companies use to manage their day to day affairs   On the macro  the software can be split into two categories  Technical and Functional  Let s go Technical first  as it answers the  What is ABAP  part of your question   Technical  There are two technical  stacks  within the SAP software  the first is the ABAP stack which is inclusive of all the original technology that SAP was   ABAP is the proprietary coding language for SAP to develop RICEFW objects  Reports  Interfaces  Conversions  Extensions  Forms and Workflows  within the ABAP stack   The ABAP stack is traditionally navigated via Transaction Codes  T-Codes  to take you to different screens within the SAP Environment   From a technical perspective  you will do all of your performance and tuning of the WORK PROCESSES in the SAP system here  as well as configuring all of the system RFCs  building user profiles and also doing the necessary interfacing between the OS  usually Windows or HPUX  and the Oracle Database  currently Enterprise 11g    The JAVA stack controls the  Netweaver  aspect of SAP which encapsulates SAP s ability to be accessed via the Internet via SAP Portal and it s ability to interface with other SAP and non-SAP legacy systems via Process Integration  PI    SAP also has extensive capabilities in the Business Intelligence Field  BI  by accessing information stored within the Business Warehouse  BW    Currently  there is a new technology called HANA 1 0 that compresses the time to run reports against these repositories   There are two primarily technologists that run ALL of these functions  they are called SAP Basis  Netweaver  Administrators and ABAP Developers   Functional  SAP has specific pre-populated functional packages for different business areas   For example  Exxon runs the  IS Oil  amp  Gas  package while Bank of America runs the  Banking  package  while further still Lockheed Martin runs the  Aerospace  amp  Defense  package   These packages were developed over time by the amalgamation of intelligent functional customizations that could be intelligently ported to the system via inclusion in dot releases   However  there are some vanilla functional modules that almost all entities run  regardless of their specific industry    HR   Human Resources PM   Project Management FI   Financial CO   Controllers MM   Materials Management SD   Sales and Distribution PP   Production Planning   and finally the biggie    MDM  Master Data Management which encapsulates the data for customer vendor material etc

See http   en wikipedia org wiki SAP AG   In short  SAP is a modular based application that sits on top of a database  as many applications do   Many people mistake SAP as being a database  but in fact it is just the application   By  modular based application  I mean that  SAP Netweaver  is a bit like  Microsoft Office  in that it is an application or set of applications that contains many components modules  With SAP you can add modules  such as Finance  HR  Banking  Logistics  etc   to meet your business requirements   ABAP is a bespoke programming language that is used within SAP  SAP also now has components that are purely ABAP based  purely JAVA based or a mixture of the two  SAP can also integrate with other technologies such as  net and PHP

SAP is a company and offers a full Enterprise Resource Planning  ERP  system  business platform  and the associated modules  financials  general ledger   amp c   ABAP is the primary programming language used to write SAP software and customizations   It would do it injustice to think of it as COBOL and SQL on steroids  but that gives you an idea   ABAP runs within the SAP system  SAP and ABAP abstract the DB and run atop various underlying DBMSs  SAP produces other things as well and even publicly says they dabble in Java and even produce a J2EE container  but tried-and-true SAP is ABAP through-and-through

Attempt to provide simplified explanation      SAP    Firstly it is a product  Owner company  derives its name with the product name  SAP  It is a management system  i e  referred as ERP   Which means  this is a tool used for  managing the system   domain specific - finance etc      Now  that SAP has created an environment around SAP  In order to operate in SAP environment  i e  for customisations etc    language-abstraction was required  Here comes ABAP      ABAP    It is a language  high level   which is used in the SAP environment for customisations or new feature implementations  It is high-level  because  it is known only in SAP environment    Therefore  any customisation on the basic version of SAP given to some customer of SAP would require ABAP usage  otherwise  just delivered SAP is good enough for usage  i e  no ABAP required    Now is another term HANA      HANA    This is an in-memory RDBMS  Another tool product by SAP  you would say  and its prime focus is to facilitate  analytics   The way  this is designed  gives high compression  column-wise storage  and hence is majorly used for  READ  operations  which is why it is associated with  analysis     SAP and HANA together abstracts the underlying complexity of database-access queries and UI  developed in java   together  to make the user experience good for the management system  used majorly in analytics  and so that the main focus stays in analytics   This very specific tool product  is said as  technology   as it has an environment of its own  terminologies etc    ABAP facilitates further development of the SAP-ERP   The underlying development is in C  C    and ABAP  for SAP
