![]() I am now quite familiar with SQLite databases, their design, structure and how to write fairly complex queries. Obviously changing things is a whole different level of commitment than looking around.Ĭlick to expand.My LambTracker program is based on an SQLite Database so I have all sorts of tools I use. The other day I tried finding where the XMP/IPTC Date Created was, and finally just gave up - it's not stored consistently, and I could never find a query to give the same value all the time as Lightroom (notably its absence, my guess due to some defaulting). For example, I run a quick report each year showing all galleries with a certain word in the name, in the calendar year, as it represents trips to those locations for tax purposes. If you are looking for something simple it is easy. This is especially true in publishing related plugins, as I do not think the API provides a mechanism to extend the database, so they just stuff data tables inside of columns. You'll find some columns, for example, with metadata stored as XML and value pairs (and sometimes both) all stuffed in a single column, not normalized out at all. The areas where it becomes very confusing are those areas you can tell were added later, and someone said "screw normalization just stuff it in there". Things you might think of as the "original" Lightroom are really quite well structured. You can also see how it handles root file moves, etc. ![]() GUID's used in addition to integer keys, why?) but you can pretty quickly track through (as an example) the image to the folder to the root, to form the path name to a file. You have no documentation, so you have to read between the lines, and sometimes wonder (e.g. Our list includes free database design tools as well as advanced, more professional data management tools.Like most legacy databases, there is good and bad. We have created a list of tools that support the process of creating database structure and its content. With a user-friendly interface, browsing the structure is possible even for non-IT people. The tools allow users to edit the visual layout using simple drag-and-drop functions. This increases the risk of errors at the initial stage. Without proper software, development is based on raw code. ![]() Additionally, some of them allow the visual representation of data using ERD, makes it easier to visualize even more complex schemas.
