The TECHShow 2022 is today and it’s happening at the Aix-en-Provence Congress Center.
Michel Payan and Séverine Payan are waiting for you on the dbSQWare stand to present our multi-DBMS operating and maintenance software.
A good day in perspective, made of meetings and exchanges, multiple and varied.

Good event to all!

A statistic (on a table, a column / a set of columns or on an index) provides information on:
– the table (number of lines, average size of a line, number of blocks/page, density),
– the distribution of values ​​for the column(s) (number of distinct values, number of duplicates, existence of null values, histogram of distribution of values),
– the composition of the index (depth, number of blocks, cluster ratio).

These statistics are used by the database optimizer to study the different execution plans that can be used for a query.
The optimizer (based on costs / CBO) chooses the best execution plan (least expensive) from the data calculated from these statistics on, in particular, the number of rows and blocks of data to be shuffled at each stage of these plans (access strategies).

Statistics are essential for the proper calculation of query execution plans. It is therefore essential that they are up to date to take into account changes to the data and therefore to the indexes, columns and tables.
Thanks to update statistics, the optimizer has reliable data to choose the best performing execution plan to serve data to applications.

Initially implemented exclusively in the Paris region, our software dbSQWare has since made its way.
It’s thanks to our users: their trust, loyalty and high standards.
The software is constantly evolving to meet customer needs.
This year, 6 patches have completed and enriched the 2022 version of dbSQWare.
The 7th will be released in a few days while waiting for the 2023 version…

Welcome to Alban Vassallo, our new database administrator!

Alban joined dbSQWare yesterday.
We are very happy with his arrival in the team.

An optimized database improves query performance, reduces processing times and reduces resource consumption (CPU, RAM, Storage, etc.). This is why it is essential to maintain an efficient organization of databases.

Hence the need for reorganization when this is not the case.
This task consists of physically reorganizing indexes and/or tables with the aim of optimizing the use of disk space and improving access to data (through their organization), recovering unused disk space, left by deleted records and/or data updates.

The operation to be carried out depends on the degree of dispersion of the index (or table) information in the database (called fragmentation):
– compaction (REORGANIZE or COMPACT) is often necessary for fragmentation between 10 and 30%
– beyond that, a reconstruction (REBUILD) must be carried out.
A “side effect” of rebuilding a table is rebuilding all of its indexes.

In any case, a successful database is a database that is monitored and maintained.

Welcome to Julien Cornand and Ewan Ducouet who started their new alternation yesterday!
Both are in Bachelor 3. Julien is training as a system and network administrator from CESI and Ewan is training as a computer and information systems expert from AIX YNOV CAMPUS.
We are delighted to welcome them to our team.

We also wish a good continuation to 2 of our work-study students, who after a year of apprenticeship at dbSQWare, are leaving for new horizons: Agnès Nagamany, on the international trade side and Ruben Ruiz, on the cybersecurity side.

Good way to all!

This evening, Festive Evening of the Club Informatique Provence Méditerranée – CIP, at the TheCamp innovation center, in Aix-en-Provence.

dbSQWare will participate with great pleasure in this annual event, expected by all.
Theme of the evening: “Summer Party”… Atmosphere assured!

Congratulations to the members of the CIP for the organization and good evening to all the participants!

The 31st edition of COTER-NUMERIQUE (the 1st for dbSQWare) has come to an end.

A big thank you to all the decision-makers who came to meet our team during this show.
Discussing the management of database engines is always a pleasure for Séverine Payan and Michel Payan.

Congratulations to Antoine Trillard and his entire team for the organization and the quality of the event.
Looking forward to the next edition, in 2023, in Deauville.

Thank you also to our colleagues and partners for their great sympathy.

– “The environment copy, what is it for?”

The environment copy allows you to duplicate an environment and thus have 2 identical environments (same structure, same tables, same data) on 2 different servers.

The interest is to have, for example, a development environment identical to that of production (in the case where the prod environment is copied in dev) and to provide developers with a working base reliable and up-to-date before they start coding (Caution, it may be necessary to anonymize the data!).
In other cases, the environment copy can make it possible to put a test environment into production, if it has successfully passed all the validation stages, or to set up a DRP (Disaster Recovery Plan) on D-1.

Finally, if the duplication is done through backups, this makes it possible to validate their viability.

This evening, afterwork “Incontournable Nice – Sophia Antipolis” organized by the Club Informatique Provence Méditerranée – CIP.

dbSQWare will be present during this unique event which will begin in Le Muy, with a visit to the company Mecatech, which specializes in the machining of industrial parts, and will continue in Les Arcs-sur-Argens with a visit to the Domaine de Font du Broc and its remarkable vineyard.

Exchanges, conviviality and networking will be there.
Good Indispensable to all the participants who will have the chance to be present and a big congratulations to the CIP for the organization of this exceptional event!
