 checkpoints is not only helpful for complying with strict regulatory frameworks, but also helps during development 
 and debugging of your Spark-based data processing.
 
+## Motivation
+
+Big Data strategy for a company usually includes data gathering and ingestion processes.
+That is the definition of how data from different systems operating inside a company
+are gathered and stored for further analysis and reporting. An ingestion processes can involve
+various transformations like:
+* Converting between data formats (XML, CSV, etc.)
+* Data type casting, for example converting XML strings to numeric values
+* Joining reference tables. For example this can include enriching existing
+  data with additional information available through dictionary mappings.
+  This constitutes a common ETL (Extract, Transform and Load) process.
+
+During such transformations, sometimes data can get corrupted (e.g. during casting), records can
+get added or lost. For instance, *outer joining* a table holding duplicate keys can result in records explosion.
+And *inner joining* a table which has no matching keys for some records will result in loss of records.
+
+In regulated industries it is crucial to ensure data integrity and accuracy. For instance, in the banking industry
+the BCBS set of regulations requires analysis and reporting to be based on data accuracy and integrity principles.
+Thus it is critical at the ingestion stage to preserve the accuracy and integrity of the data gathered from a
+source system.
+
+The purpose of Atum is to provide means of ensuring no critical fields have been modified during the processing and no 
+records are added or lost. To do this the library provides an ability to calculate *control numbers* of explicitly 
+specified columns using a selection of agregate function. We call the set of such measurements at a given time
+a *checkpoint* and each value - a result of the function computation - we call a *control measurement*. Checkpoints can 
+be calculated anytime between Spark transformations and actions, so as at the start of the process or after its end.
+
+We assume the data for ETL are processed in a series of batch jobs. Let's call each data set for a given batch
+job a *batch*. All checkpoints are calculated for a specific batch.
