12
12 tcACCESS SQL Engine More than 90 SQL functions supported Operators (+, -, *, /, ||) Conditional Operators (>, <, =, BETWEEN, LIKE) Logic Operators (AND, OR) INNER and OUTER JOINS GROUP BY, ORDER BY Security may be applied (RACF, ACF/2, Top Secret) Stored Procedure Support
13
13 tcACCESS SQL Engine Different data sources can be JOINed: SELECT IMS.NR, IMS.NAME, VSAM.ADDRESS FROM IMS, VSAM WHERE IMS.NR = VSAM.ID VIEWS can be created Control Options available (MAXIO, MAXROW, NOORDERBY, etc) Global SQL Exit available Field Level Exits available

20
20 Mainframe Change Data Capture Change Data Capture Efficient transfer of entire databases Analysis for data consistancy Best for Initial Load prior to log processing Best for periodic mass data transfer One step data transfer
21
21 Mainframe Change Data Capture Change Data Capture Comparison of data snapshots Efficient transfer of changed data since last processing IMS/DB, DL/I, VSAM, DB/2, ADABAS, CA-IDMS, DATACOM, sequential files Flexible processing options (SORT etc.) Automatic creation of deltas by tcVISION
22
22 Mainframe Change Data Capture Change Data Capture Usage of the DBMS logging capabilities IMS/DB, VSAM, DB/2, DL/I, ADABAS, IDMS, DATACOM Transfer of changed data in scheduled time frame Best for batch window Best for processing right after logfile creation
23
23 Mainframe Change Data Capture Change Data Capture Realtime capture of changed data Changes directly obtained from DBMS CA-IDMS, IMS/DB, VSAM, DB/2, DATACOM, ADABAS Secure data storage even across DBMS restart Flexible propagation methods
