ADABAS Data Structures

All standard data formats are supported: alphanumeric, binary, fixed point, floating point,

packed decimal, unpacked decimal, ... Supports two basic field types

Elementary fields “recurring fields” (MUs)

Consecutive fields may be grouped A group may be repeated - Periodic Groups (PEs) Periodic Groups may contain one or more Multiple-

Value Fields

9 TSI 4/05

ADABAS Data Structures continued

ADABAS has unique data structures:Multi-Valued Fields - “MUs” (array structure) Periodic-Groups - “PEs” (table structure) MUs in PEs (multi-dimensional structure)

ADABAS has some “difficult” data types IBM STCK-based Date and TimeStamp fields

EBCDIC to ASCIIPacked FieldsSign Byte Handling

10 TSI 4/05

ADABAS Extraction Facts FACT #1

NATURAL was developed by Software AG specifically to access ADABAS

FACT #2NATURAL represents the most widely used AND best understood solution for accessing ADABAS

FACT #3What NATURAL should not be used to do, ADABAS Utilities handle (with support from NATURAL)

FACT #4Extraction / CDC should be done in BATCH

11 TSI 4/05

ADABAS Extraction - Conclusions Natural allows flexible ADABAS Access Natural easily handles all ADABAS data

structures Natural easily handles all ADABAS data types Natural will always work with ADABAS

The NatQuery Extraction SolutionNatQuery works by acting as an on-demand Natural Programmer.

From a graphical user interface a User is enabled to:

Create Query Specifications Generate Natural Data Extraction programs from

these Specifications Submit Generated Extract programs for execution Remotely monitor execution status Download Extracted Data Load extracted data into MS Access, MS Excel or

convert data into XML (with optional XSL)

Generation Component

Internally, NatQuery can be thought of as having three components:

Administrative Component End-User Component Generation Component

18 TSI 4/05

The NatQuery Extraction Solution

Administration Component

NatQuery

Generation Component

The Administrative Component is used by an Administrator to capture information that is specific to the platform, environment, and ADABAS data files that NatQuery will be used against.

The Administration Component provides NatQuery with the ability to capture application-specific intelligence.

The NatQuery Extraction Solution

Better control of requests Request execution can be easily scheduled Impact on online production applications are controlled

More efficient execution environment over “online” Significantly Less overhead

NatQuery handles Job Control Language (JCL) Template approach provides easy set-up /

maintenance Dynamic substitution makes templates executable

Requests Execute in “batch”

ADABAS CDC (Change Data Capture)

PLOG contains all transactions against all Files PLOG is in compressed format

The same compression used by ADABAS PLOG data is stored in Variable-Length records

Different from file to file and within same file PLOG data requires “conversion”

EBCDIC to ASCII, date / time formats

Issues in accessing PLOG:

45 TSI 4/05

ADASEL utility (ADABAS 6): “Splits” PLOG transactions into separate files

– One File for each requested ADABAS File– Handles Expanded Files

Decompresses PLOG records ADACDC utility (ADABAS 7):

everything ADASEL does direct delivery of Delta changes

ADABAS CDC

ADABAS utilities solve most PLOG issues:

46 TSI 4/05

NatCDC converts variable-length to fixed-length User-Specified number of MU and PE occurrences PLOG Header converted

– IBM STCK time, Expanded File ISNs are normalized NatQuery generates all required objects
