Digital asset management (DAM) consists of management tasks and decisions surrounding the ingestion, annotation, cataloguing, storage, retrieval and distribution of digital assets. Digital photographs, animations, videos and music exemplify the target-areas of media asset management (a sub-category of DAM).
Digital asset management systems (DAMS) include computer software and hardware systems that aid in the process of digital asset management.
The term "digital asset management" (DAM) also refers to the protocol for downloading, renaming, backing up, rating, grouping, archiving, optimizing, maintaining, thinning, and exporting files.
The "media asset management" (MAM) sub-category of digital asset management mainly addresses audio, video and other media content. The more recent concept of enterprise content management (ECM) often deals with solutions which address similar features but in a wider range of industries or applications.
Smaller DAM systems are easier to categorize as to content and usage since they normally operate in a particular operational context. This would hold true for systems attached to audio or video production systems. The key differentiators here are the type of decoders and I/O (input/output) used for the asset ingest, use and outgest. Since metadata describes the essence (and proxy copies), the metadata can serve as a guide to the playout decoders, transcoders, and channels as well as an input to access control rules. This means that the essence can be treated as a non-described storage object except when being accessed for viewing or editing. There is relevance to this when considering the overall design and use of larger implementations. The closer the asset is to the ingest/edit/playout tool, the greater the technical architecture needs to accommodate delivery requirements such as bandwidth, latency, capacity, access control, availability of resources, etc. The further the asset moves into a general storage architecture (e.g. hierarchical storage management ) the more it can be treated as a general blob (binary large object) that is typically held in the filesystem, not the database. The impact of this set of needs means that it is possible and reasonable to design larger systems using smaller, more expensive performance-systems at the edge of the network where the essence is being used in its intended form and less expensive systems further back for storage and archival. This type of design exemplifies Infrastructure Convergence Architecture, where the line-of-business operations technology and IT technologies depend on one another for functional and performance (non-functional) requirements.

Famous quotes containing the words asset and/or management:
“When ... did the word “temperament” come into fashion with us?... whatever it stands for, it long since became a great social asset for women, and a great social excuse for men. Perhaps it came in when we discovered that artists were human beings.”
—Katharine Fullerton Gerould (1879–1944)
“No officer should be required or permitted to take part in the management of political organizations, caucuses, conventions, or election campaigns. Their right to vote and to express their views on public questions, either orally or through the press, is not denied, provided it does not interfere with the discharge of their official duties. No assessment for political purposes on officers or subordinates should be allowed.”
—Rutherford Birchard Hayes (1822–1893)
