Databases at the HTBC
We support two main databases; A cheminformatics database originally from MDL/Accelrys (now Dassault Systemes Biovia) (ORACLE 9i) and an image storage and analysis database from Molecular Devices (ORACLE 11g).
HTS and Cheminformatics Database
1. The High-throughput Database stores all the information from the compound libraries and links this information together with the results from screening. The cheminformatics system we installed is originally from MDL Information systems and contains the following products:
(A) MDL ISIS Enterprise Edition (datasheet) including, ISIS/Draw (datasheet), ISIS/Base (datasheet), ISIS for Excel,(datasheet), ISIS/Host with Oracle Gateway, Chime Pro/Chemscape Server, developer tools, ISIS ADK Pro, ISIS/Host API, ISIS Open Gateway & Toolkit, Relational Chemistry Server, and MDL Draw Enterprise Edition.
High-Content Image Storage and Image Analysis Database
2. The Molecular Devices MetaXpress image acquisition software captures and stores image files from the ImageXpress Micro during high-content screens. The images are stored in the MDCStore database which can use either Oracle or Microsoft SQL Server database. MetaXpress is also used for image analysis, through the use of custom scripts or analysis application modules. Thus, these combined applications not only store the image files, but also the image analysis results.
The data is stored on 4 Dell PowerEdge Database Servers. Two are PowerEdge 2650 running Microsoft Windows Server 2003 and ORACLE 9.2 (HTS database) or ORACLE 10.2 (old Image Storage database). Each server is attached to external Powervault 220S RAID5 arrays (one with >3 TB of RAID5 SCSI storage for high-content image file backup). The two other servers are Dell Poweredge R810 servers running Windows Server 2008 and ORACLE 11.2. These servers are attached to external Powervault MD1220 RAID6 arrays (one with >10 TB of RAID6 SAS storage for high-content image files). A Dell Powervault TL4000 LTO-4 automated Tape Backup with 48 slots for 800GB LTO-4 tapes is utilized to backup all data and image files with Veritas Backup Exec 12.5.
