The volume of data is increasing rapidly with increases of one to two orders of the magnitude expected in one or two years. The challenges and the costs of preserving and enabling access to these growing data sets are growing with time. The larger data volumes place increasing demands on developing tools for finding data and for extracting small subsets. Space research and practical applications increasingly require the integration of a wide variety of data sets, which are commonly stored in different data models and formats. Oracle is widely used by space research organisations for data storage and decision making. Oracle provide a common set of querying tools so that it becomes possible for users to integrate data across different space centers and to combine data from the active archives with data from long-term data centers in order to identify patterns (e. g. , environmental influences on galaxy evolution) and monitor long-term variations and trends (e. g. in land use or climate). .

Another approach is to focus more on learning one programming language well. Once you're proficient at one language, the next one will be easier (just like learning natural languages). Some programming fundamentals stick with you across languages. If you can't decide, go with the programming language approach. If you don't have a favorite language, go with JavaScript or Python. Don't worry too much about different fields or topics. For your first job, it's not very important what your background is. No one who is looking for an entry-level programming job has very much real-world experience. But the more programming time (in any language) you have under your belt the better.
