Spring Manually Rollback Transaction

First of all, there is no rollback of an exception, its a rollback of a transaction. If you throw your exception with ApplicationExceptionrollbacktrue, you dont.

There are multiple ways to model trajectory data. This post takes a closer look at the OGC Moving Features Encoding Extension Simple Comma Separated Values CSV. This standard has been published in 2. I havent been able to find any reviews of the standard in a GIS context or anywhere else. The following analysis is based on the official OGC trajcectory example at http docs. The header consists of two lines the first line provides some meta information while the second defines the CSV columns. The data model is segment based. That is, each line describes a trajectory segment with at least two coordinate pairs or triplets for 3. D trajectories. For each segment, there is a start and an end time which can be specified as absolute or relative offset values stboundedby,urn x ogc def crs EPSG 6. D,5. 0. 2. 3 9. 2.

My main issues with this approach are. They missed the chance to use WKT notation to make the CSV easily readable by existing GIS tools. As far as I can see, the data model requires a regular sampling interval because there is no way to store time stamps for intermediate positions along trajectory segments. Irregular intervals can be stored using segments for each pair of consecutive locations. In the common GIS simple feature data model which is point based, the same data would look something like this trajid,x,y,t,state,typecodea,1. T1. 2 3. 3 5. 1Z,walking,1a,1.

T1. 2 3. 6 5. 1Z,vehicle,1. The main issue here is that there has to be some application logic that knows how to translate from points to trajectory. Spring Manually Rollback Transaction' title='Spring Manually Rollback Transaction' />For example, trajectory a changes from walking. T1. 2 3. 6 1. 1Z but we have to decide whether to store the previous or the following state code for this individual point. An alternative to the common simple feature model is the Post. GIS trajectory data model which is Line. String. M based.  For this data model, we need to convert time stamps to numeric values, e. T1. 2 3. 3 4. 1Z is 1. Unix time. In this data model, the data looks like this trajid,trajectory,state,typecodea,LINESTRINGM1. LINESTRINGM1. 2. LINESTRINGM1. LINESTRINGM1. 2. This is very similar to the OGC data model, with the notable difference that every position is time stamped instead of just having segment start and end times. If one has movement data which is recorded at regular intervals, the OGC data model can be a bit more compact, but if the trajectories are sampled at irregular intervals, each point pair will have to be modeled as a separate segment. Since the Post. GIS data model is flexible, explicit, and comes with existing GIS tool support, its my clear favorite.
