Die Datenbank enthält Informationen zu Bau- und Kunstdenkmalen, zu Gartendenkmalen und technischen Denkmalen im Land Brandenburg. Der Datenbestand stellt einen Auszug aus der HiDA4-Fachdatenbank der Baudenkmalpflege des BLDAM dar. Er wird kontinuierlich ergänzt.

InfluxDB is a time series, metrics, and analytics database. It’s written in Go and has no external dependencies. That means once you install it there’s nothing else to manage (such as Redis, ZooKeeper, Cassandra, HBase, or anything else). InfluxDB is targeted at use cases for DevOps, metrics, sensor data, and real-time analytics. It arose from our need for a database like this on more than a few previous products we’ve built. You can read more about our journey from SaaS application to open source time series database.

UnQL means Unstructured Query Language. It's an open query language for JSON, semi-structured and document databases.

Über die Jahre verteilen sich E-Mails über unterschiedliche Programme und Postfächer, gehen durch defekte PST-Dateien oder unvollständige Datensicherungen verloren und können nur noch langsam durchsucht werden. Mit MailStore Home können Sie alle E-Mails zu einem sicheren Archiv zusammenführen, schnell durchsuchen und z. B. per Mausklick auf CDs oder DVDs brennen.

The goal of the project is to create a high-performance and easy to use tool for the SQL queries logging for JDBC applications.

Features include:

* can be attached on Connection, Driver or DataSource(XA,Pooling) levels
* can log bind parameters for PreparedStatement and CallableStatement calls
* can log result of queries from ResultSet objects
* can log queries execution time
* logging engine agnostic (thanks to SLF4J, you can use most of popular logging libraries like log4j, apache common logging, java logging or simple printing to System.out)

User agents need to store large numbers of objects locally in order to satisfy off-line data requirements of Web applications. [WebStorage] is useful for storing pairs of keys and their corresponding values. However, it does not provide in-order retrieval of keys, efficient searching over values, or storage of duplicate values for a key.

LiquiBase is an open source (LGPL), DBMS-independent library for tracking, managing and applying database changes. It is built on a simple premise: All database changes (structure and data) are stored in an XML-based descriptive manner and checked into so
