The data management system JAZELLE has been created as a successor to earlier HEP data managers such as YBOS and ZEBRA. While it has many similarities with these systems it also has many enhancements such as self-documenting data descriptions, mnemonic access to all data, relational data structures, powerful machine independent IO facilities including network IO, and many mechanisms for presenting data to the physicist in an intuitive manner. The emphasis has been on producing a powerful, use friendly, data management system which can be accessed from many languages as a natural extension of these languages. Within the SLD collaboration JAZELLE has been used to manage the experimental data all the way from the SLD online VAX to the end to the reconstruction chain and physics analysis. Beyond this, JAZELLE is also used to store calibration constants and correction factors, detector geometry, physics parameters (such as particles masses and branching ratios) and program control parameters. JAZELLE has also been interfaced to the interactive data analysis program IDA. The uniform usage of JAZELLE throughout SLD coupled with its interface to IDA has produced an environment in which rapid interactive access to data is greatly simplified. JAZELLE and IDA together provide an analysis environment greatly superior to any standard programming language.
