How does TABEX4 save time?

  • The completely configurable TABEX4 table management system minimizes your programming efforts: if you have spent, for example, up to one full programming day for just one single DB2 table maintenance transaction, this effort can be avoided in the future and you benefit from all of TABEX4’s advantages, e.g. the high security standard.

  • The standardized table maintenance routines of TABEX4 minimize time needed for application programming and maintenance. Thus your employees have more time and energy to accomplish core activities.

Why do BOI customers use TABEX4?

Our customers use TABEX4 for high-performance table access and management and administration of their corporate tables.

  • TABEX4 allows high-performance access to table data using application programs, irrespective of the database where the data are stored. Application programs use TABEX4 access functions for billions of transactions per day.
  • TABEX4 is used for maintenance and administration of all corporate tables. Table sizes range from just a few records up to several thousand records - easy and comfortable
  • With TABEX4 you can manage table data, mostly from relational databases without programming. For example, one of our customers modifies 10,000 DB2 tables using the TABEX4 table manager without any own application.
  • TABEX4 is used for the unlimited transfer of data across platforms and databases.
  • TABEX4 replication technique synchronizes tables across platforms; thus all data are available identically in different IT environments. So tables can be copied from one relational database in one specific platform to another database in another platform.


How much time and effort is needed for a new installation?

Installation itself doesn't need mach time. The customer specific configuration – the customization of TABEX4 to the individual needs of the customer – depends on the size of the enterprise. BOI supports customers during configuration. Our goal is to achieve a successful and satisfying customer configuration.

Which advantages does TABEX4 offer?

TABEX4 offers better organized table management.

  • TABEX4 runs identically and stable in heterogeneous IT environments: ONE standard software for all platforms and all databases of your company.
  • TABEX4 offers comfortable and safe management of tables stored in DB2 and other relational databases (e.g. Oracle, MS SQL Server, IBM Informix, PostgreSQL, MySQL, …), without programming, but with easy-to-define check routines. Any checks e.g. for referential integrity may directly be inherited from the relational database.
  • TABEX4 fulfills all requirements of IT revision und compliance.
  • TABEX4 is multitenant: the TABEX4 instance concept (question 15 – What is the TABEX4 Instance Concept?) maps your organizational structures optimally: you can define instances for different departments or use instances to map different production levels, e.g. development, testing and production.
  • TABEX4 is fully configurable and thus can be optimally adapted to your specific requirements.
  • TABEX4 offers comprehensive options for data checks: check tables for complex checking rules, RI-checks (insert rules, update rules, delete rules), key-checks (check the uniqueness of a table key) and field check routines (check of value ranges).
  • TABEX4 runs independently of platform or database. Tables can thus be managed on various platforms and can be moved across different platforms.
  • TABEX4 offers an integrated authorization system. External authorization systems such as RACF or ACF2 can be integrated.
  • TABEX4 has an ergonomic browser interface of highest usability.

How does TABEX4 save resources?

High performance access to table data economizes resources: according to z/OS benchmarks, TABEX4 table access results in a performance improvement between 1:10 to 1:50 compared to direct DB2-access. This leads to tremendous license cost savings.


How does TABEX4 save money?

  • CPU-savings of up to 98% reduce license costs.
  • The standard software TABEX4 saves development costs and minimizes maintenance and administration costs.
  • TABEX4 works independent of platform or database and thus one single software solution can replace several backend systems or other table management systems with their respective license and maintenance costs.
  • TABEX has an excellent price-performance ratio.

Does TABEX4 fulfil revision requirements?

  • access protection by a comprehensive authorization system; other authorization systems can be integrated
  • release procedure with four-eyes principle
  • complete logging and documentation of any data change
  • extensive checks to guarantee consistency and plausibility
  • integrated table versioning allowing access to version-controlled data which is valid to a given date.


How much time and effort is needed to migrate from another system?

The magnitude of features available in TABEX4 allows a quick migration from other table management systems to TABEX4.  We have successfully carried out migration from other table management systems for our customers. As TABEX4 uses a compatibility interface, no changes in the existing application programs need to be made. The time and effort needed for migration is thus very small: for example, a migration from TABSYS to TABEX4 took only one day.

TABEX4 is multi-tenant. Besides the general configuration of TABEX4 at company level, you can configure so-called instances as sub-systems e.g. at department level or for a group of selected users, but also for different levels of production. An instance is a predefined “configuration-set” that restricts contents and available features to specific user-groups.
