"""
This abstract class DbFcts defines the interface for any function relating to any kind of a database-management.
It uses the following configuration
.a) COMP.conf->artifact->db->[table] : for structural attributes of the database, maybe specialized for tables \n
.b) COMP.conf->artifact->ddl : for structural attributes of the database-tables \n
.c) COMP.conf->conn->[db] : for connection-attributes and structural attributes, maybe specialized for the database
The attribute db.type resolves which technique is used, implemented in a specific tool-class:
* db2,mysql,pgsql,(s)hive ... for specific synchronous RDBs
* spark,shive,sfile ... using spark-technology
* csv,(s)file ... for data managed in files
The main tasks are: \n
.1. connecting to the datebase - with attributes
* conn.ip, host, port, user, password, ... for synchronous db-connection
* conn.root, ... for path-definitions for file-implementations (csv, )
.2. delete at the initialisation - with
* db.reset for the context testcase, testsuite or never, on which the content will be deleted - default: testcase
* db.character of the table if the content will be be deleted in a sequence of testcases
* db.tabname -- if the tablename is differs from the node-name of the table - default: not necessary
* db.filename -- if the filename is differs from the node-name of the table - default: not necessary
* par.dbwhere which rows will be deleted - default empty
.3. insert testdata at the initialisation
* ddl.[fields]
* db.tabname - if the tablename is differs from the node-name of the table - default: not necessary
* db.filename - if the filename is differs from the node-name of the table - default: not necessary
.4. select the data with
* db.tabname - if the tablename is differs from the node-name of the table - default: not necessary
* db.filename - if the filename is differs from the node-name of the table - default: not necessary
* ddl._data.[fields].order for an order-clause
* par.dbwhere which rows will be deleted - default empty
SPECIAL CASES:
* If the table is partitioned tables the functions delete/insert/select calls the callback-functions
COMP.nextTable() resp. COMP.nextTdata().
